Affordable 10G SFP+ Switches for SMB Hyper-Converged Appliance Expansion

Hyper-converged infrastructure (HCI) has been earning a good reputation in data centers, whether it is of the entire branch offices, the IT duties of small and medium businesses (SMBs) or the virtual desktop infrastructure deployments. HCI offers numerous integrated services such as backup, data protection and solid-state drive storage, and allows seamless management and expansion of various compute, storage and network devices, i.e., users can scale the network flexibly by adding a new appliance to the hyper-converged cluster. For SMBs, the requirements for network switches is not the same as large enterprises when adding a 10G appliance. This post is to suggest some affordable 10G SFP+ switches for SMBs during hyper-converged appliance (HCA) expansion.

10G SFP+ Switches Requirements for SMB HCA Expansion

In today’s SMBs, applications are requiring higher data rate and some management features. For a SMB with a considerable size, the core switches might be required to a fully-managed switch with strong capacity, high bandwidth and high port count. The switches for the connectivity of the cluster (compute, storage and network devices) may also have many ports. But when adding new appliance to the cluster, the switch usually needs not to be high port count or with high data rate. A 8-12 ports 10G SFP+ switch is generally enough for hyper-converged appliance expansion, which is rational considering the expenditure for expansion as well. The following table gives some 8-12 ports 10G SFP+ switches in the market for your reference.

Switch Model Ports Switching Capacity Fowarding Rate Switching Layer Price
Dell X4012 12 x 10G SFP+ 240 Gbps 178.6 Mpps L2+ $1,063.54
Netgear M4300-8X8F 8 x 10G SFP+ and 8 x 10GBASE-T 320 Gbps 238.1 Mpps L3 $1,719.00
Cisco SG500XG-8F8T 8 x 10G SFP+ and 8 x 10GBASE-T 320 Gbps 238.1 Mpps L3 $2,146.59
FS S5800-8TF12S 12 x 10G SFP+ and 8 x 1GBASE-T/SFP Combo 240 Gbps 178.6 Mpps L3 $1,699.00
D-link DXS-1210-12SC 10 x 10G SFP+ and 2 x 10GBASE-T/SFP+ Combo 240 Gbps 178.6 Mpps L3 $1,055.00

According to the information available, these switches can be got online well under $3K in brand new condition. Suppose that a SMB has a core switch which has a fabric capacity of 960 Gbps, and now it needs to add 5 nodes of 10G speed to the cluster for downstream, an 8-12 ports 10G SFP+ switch will not only give enough ports for current nodes and for uplink to the core, but also gives the SMB space to grow.

These switches have some features in common. These common features are very helpful in SMB network managing and ensuring data quality.

Management and Functionality Services

For all the switches mentioned above, some of them are fully managed switches while some are smart managed switches. But all of them are not limited to web interface management. They also support Command Line Interface (CLI), Telnet (multi-session support), SSH and SNMP (simple network management protocol). The most functions that a SMB might need are all equipped, such as VLAN, port mirroring, LACP (link aggregation control protocol) and RMON (remote network control).

QoS and Security Features

The QoS (Quality of Service) features include ARP (Address Resolution Protocol) inspection, ACLs (Access Control Lists), DSCP remark, etc. These features can contribute a lot in securing the SMB network, for example, with the help of ARP inspection and ACLs, the switch can block fake ARP entries outside the system, so that data frames will not be easily sniffed or modified. Broadcast Storm Control is also supported in order to avoid traffic disorder caused by malicious attack from intruders.

How to Connect These 10G SFP+ Switches?

Although these 10G SFP+ switches chosen for SMB hyper-converged appliance expansion are relatively low-priced, but the OEM 10G SFP+ fiber transceivers can overburden a SMB if bought in large quantity. Four OEM 10G SFP+ transceivers can cost as much as a 10G SFP+ switch we have found above. Fortunately, there is way to release the SMBs from expensive OEM optics. That is cost-effective 10G SFP+ compatible modules. So the total cost for the HCA expansion will not exceed $3k either. In addition, most OEM switches support third party transceiver modules and DAC cables from third party transceiver vendors.

Summary

In sum, for SMB hyper-converged appliance expansion, the 10G SFP+ switches used to connect the core switch and the cluster need not to be high port count, but should be equipped with enough management functions for SMB applications.

What’s the Difference: FET-10G vs. SFP-10G-SR

You must be puzzled by the two different short reach optical transceivers for a long time: FET-10G vs. SFP-10G-SR. What’s their difference? Does the connection work if we connect Cisco Nexus switches with FET-10G on one end and SFP-10G-SR on the other end? With these questions in mind, I’d like to invite you to keep reading the article.

FET-10G vs. SFP-10G-SR Difference

FET-10G vs. SFP-10G-SR are Cisco brand for building short network. FET is short for “Fabric Extender”. Just as its name implies, this module can only support fabric links from a Nexus 2000 to a Cisco parent switch. Fabric Extender transceiver can support link lengths up to 100m over OM3 or OM4 multimode fiber cable. SFP-10G-SR transceiver supports link lengths of 26m on standard fiber distributed data interface-grade multimode fiber cable. The link lengths can reach up to 300m over OM3 fiber cable and 400m over OM4 fiber optic jumpers. You can learn some small differences from the following table.

Can We Connect FET-10G With SFP-10G-SR

In Cisco Nexus switch, do the transceivers have t ends in order for the connection to work? Does FET module have to be linked with another FET module? Now there is a FET-10G module in Cisco Nexus 2000 series fabric extender and SFP-10G-SR in a Nexus 5000 series switch. Can this connection work normally? Before making a judgement, let’s first compare the power of FET-10G and SFP-10G-SR.

SFP+ Module Transmit Power (dBm) Receive Power (dBm)
Max. Min. Max. Min.
FET-10G -1.3 -8 -1 -9.9
SFP-10G-SR -1.2 -7.3 -1.0 -9.9

From the above chart, transmit power and receiver power are different. And it has mentioned before that FET-10G vs. SFP-10G-SR support different network distance over the same fiber cable. Therefore, we can get a conclusion that FET-10G transceiver have to be connected with another FET-10G module. If we build a connection with SFP-10G-SR into the Nexus 5000 and FET-10G in Nexus 2000, it won’t work.

For better connection, when using FET-10G fabric extender transceiver, you should follow these rules:
1. FET-10G only supports fabric links, for instance, fabric links from a Nexus 2000 series to a Cisco parent switch.
2. Cisco fabric extender transceiver must be connected to another fabric extender transceiver, FET-10G to FET-10G.
3. FET-10G can be used for Nexus Cisco 2200 uplinks.
4. FET-10G can support fabric links on Cisco 5000, 6000, 7000 series switch.

Can We Replace FET-10G with SFP-10G-SR Modules?

FET-10G transceiver is designed to connect Cisco Nuplink ports (fabric interfaces) with the upstream parent Cisco Nexus switch. We already know that we can’t intermix FET-10G with SFP-10G-SR modules. How about plugging SFP-10G-SR transceivers into the fabric ports to connect Cisco Nexus switches? That is to say, can we replace FET-10G with SFP-10G-SR?

The answer is yes. However, it’s more expensive compared with original Cisco SFP-10G-SR transceiver. FET-10G is to provide an uplink to a Fabric Extender and save you money. If you already have them, then use them. If you making a purchasing decision, buy the FET-10G or third-party SFP-10G-SR.

FET-10G vs. SFP-10G-SR

Conclusion

From this article, you can find FET-10G vs. SFP-1T-10G is specially designed for Cisco Nexus series switches. To make sure the right connection, bear in mind that use the sane transceivers on both sides, either FET or 10G-SR. You can replace FET-10G with SFP-10G-SR while you can’t do that in turn.

Tunable SFP+ VS. Fixed Wavelength DWDM SFP+ Transceiver

Dense wavelength division multiplexing (DWDM) is one of most important technologies to increase network transmission capacity. Early DWDM systems applied fixed wavelength DWDM transceivers and performance is good. However, as the demand for great traffic capacity keeps growing, more optical transceivers of different wavelengths are needed, leading to high cost. So how to deal with that? Tunable SFP+ arises your attention.

Tunable-SFP+

What Is Tunable SFP+

Conventional DWDM SFP+ transceivers use fixed-wavelength lasers as light sources. It means that many optical transceivers are needed for the wavelength channels in a DWDM system. While tunable SFP+ is different from fixed wavelengths modules because it applies tunable laser, which can operate at any channel wavelength, means that only one kind of transceiver is needed. Tunable lasers are now widely used as light sources in DWDM systems. Tunable SFP+ modules are only available in DWDM since CWDM grid is too wide. Tunable SFP+ optics are for the C-Band 50GHz. About 88 different channels can be set with intervals of 0.4nm, which is the 50GHz band.

For better understanding, I’ll show you a tunable module. This is a Cisco Compatible 10G DWDM C-band tunable SFP+ 50GHz Transceiver. It’s hot swappable, can support 10.3Gbps data rate up to the distance of 80km over single mode LC duplex fiber patch cable. Support 1563.86nm-1528.77nm C-band tunable wavelengths.

Cisco-tunable-SFP+ optics

What you should note is that wavelengths of tunable SFP+ can be tuned only when your Cisco/Juniper/Arista/etc switch supports. If your switch only support common fixed-wavelength DWDM SFP+, you need external software to change tunable optics into certain wavelength before putting into use.

Why Tunable SFP+ Is Better Than Fixed Wavelength SFP+?

Fixed wavelength SFP+ are still in the market and not too many problems found in use. So you may feel puzzled about choosing tunable SFP+ or fixed wavelength SFP+ as tunable SFP+ is more expensive. The following will tell you why you need tunable optics.

First, save you cost. With the development of optical communication systems, the shortages of fixed-wavelength laser gradually revealed. Conventional DWDM SFP+ can lead high costs. The number of wavelengths in DWDM 50GHz has reached the hundreds. Then spare modules of each laser should be prepared for protection of the system because you don’t know which module will break down and it’s difficult to predict the number of stock in specific channels. Therefore you have to buy large quantity of DWDM SFP+ modules with fixed wavelengths. While the tunable optics are configured with different DWDM wavelengths in one module. You can select the right wavelength you need based on your optical fiber communication environment. Tunable SFP+ are typically used as “spare-optics” to save you cost.

Second, flexible network management. When running a DWDM network with lots of nodes, for instance, up to 80 different wavelengths, management could be a nightmare. You have to prepare couple of DWDM SFP+ optics of each wavelength and possibly in different locations. Field engineers may not access network nodes as quickly as you wish. Thus tunable optics would be a good choice. Tunable optics could be configured for a specific wavelength to support bandwidth changes as needed in optical network.

Third, suitable for large network capacity. As the development of increasing network transport, 400G or 1T would be the trend. Then 400G and 1T transmission formats are expected to be bulky and not fit within 50GHz spacing. These future new data rate formats require that channel spacing is flexible, that your OTN system can adapt to new rates and can re-arrange channel spacing to find place for new rates in it. Tunable optics will double the number of channels supported in this transceiver module. Upgrading to 50GHz channel spacing doubles the capacity potential in Enterprise and Metro networks.

Choose Tunable SFP+ in the Long Run

Tunable SFP+ are high-performance optics which can be tuned to the appropriate wavelength in seconds. The ability to function on various wavelengths has set these optics apart from fixed-wavelength DWDM SFP+. Tunable SFP+ will become popular among DWDM systems due to their ease of spare use and flexibility. Tunable SFP+ would be a powerful and invaluable transmission tool in high-speed network. At present, many engineers are using fixed wavelengths SFP+ transceivers. Some may be stopped by the tunable SFP+ price. But in the long run, you are suggested to consider tunable SFP+.

Core Switch & Edge Switch: How to Make a Decision?

When considering buying a new switch for your small business, you need to ask yourself a few questions: How many devices will the switch need to support? What kinds of devices will I be connecting? Has our network grown to the point where we need a switch with more advanced management capabilities? And here is an important decision you are going to make: whether core or edge for your network.

What Is A Core Switch?

A core switch, is also known as a backbone switch. It is a high-capacity switch generally positioned within the backbone or physical core of a network. Core switches serve as the gateway to a wide area network (WAN) or the Internet—they provide the final aggregation point for the network and allow multiple aggregation modules to work together. You use it to connect to servers, your Internet service provider (ISP) via a router, and to aggregate all switches that your company uses to connect crucial pieces of equipment that your company can’t afford to lose to downtime. As a result, your core switch should always be a fast, full-featured managed switch.

What Is An Edge Switch?

An edge switch also is called an access node or a service node. It is a switch located at the meeting point of two networks. These switches connect end-user local area networks (LANs) to Internet service provider (ISP) networks. Edge switches can be routers, routing switches, integrated access devices (IADs), multiplexers and a variety of MAN and WAN devices that provide entry points into enterprise or service provider core networks. Edge switches can directly connect client devices, such as laptops, desktops, security cameras, and wireless access points, to your network.

what is edge switch

Core Switch vs. Edge Switch

Generally speaking, a core switch would have more up-market features such as higher backplane speed, layer 3 including routing protocols such as OSPF, and physical redundancy features such as removable PSUs. They might not have any copper presentation at all. A core switch will typically have deeper buffers, such that multiple connections can be experiencing congestion.

Edge switches are what your desktops and phones plug directly into (at the “edge of the network”). Typically they are lighter on features and more about copper port count and some form of fibre interface into the backbone / core.

How Should I Make A Choice?

A small company with fewer than 100 employees should function well with one core switch. However, as your business—and your network—grow, you might need to expand the number of core switches to two or more. In this case, you might want to consider stackable switches, which further simplify management.

Edge switches generally are considered less crucial than core switches to a network’s smooth operation. If there are areas of the office such as a conference room where you don’t need the features of a fully managed switch, your company can save some money by installing smart switches. But if you can’t tolerate any downtime whatsoever, want to maintain tight security throughout your office, or have the infrastructure to be able to add multiple different types of applications in the future, you should consider outfitting your entire network with managed switches.

Conclusion

Fortunately, managed switches are no longer out of reach for small businesses. Not long ago the price gap between managed and smart switches was as much as 40 percent. Today, though, that difference has shrunk to 10-20 percent.

Wireless Network vs. Wired Network: Which One to Choose?

Our home networks rely on either wired (Ethernet) or wireless technology. Sometimes, we use both of them, especially when multiple Internet capable devices are set up in homes. Wireless networks enable multiple devices to use the same internet connection remotely, as well as share files and other resources. But it’s still hard to say wireless is better than wired, since each one has advantages and drawbacks. This article is meant to compare wireless and wired technology from three primary factors: mobility, reliability, and security.

wireless network anywhere

Wireless Network vs. Wired Network

wired network vs wireless network

Mobility

A wired LAN (Local Area Network) uses Ethernet cables to connect computers together directly or more commonly, through a hub, switch, or router. Wired connections typically cost much less and reduce battery drain on laptops and other mobile devices because Wi-Fi adapters use more power.

As for wireless network, users can move around freely within the area of the network with their laptops, handheld devices etc and get an internet connection. The popularity of Wi-Fi has also increased due to increased smartphone and tablet sales. Many of these devices are not capable of wired Ethernet connections and rely on wireless signals for Internet connectivity.

Reliability

Ethernet-based(wired) networks tend to be much more reliable than wireless networks. The backbone of any network relies on an Ethernet connection. The most common problem with wired network is loose cable connections. Because you have to lay lots of cables and put them through walls etc. A bundle of tangled wires can result in damage and performance degradation. Using Zip-Ties is an excellent way to keep cables out of the way and tangle-free.

For the most part, wireless technology is reliable. There are some concerns about interference from home appliances such as microwaves and cordless phones, but most wireless routers provide multiple channels that can mitigate this concern relatively easily.

Security

The security of a home-based Ethernet network is almost primarily dependent upon a firewall. Most broadband routers include a firewall already and software firewalls can also be installed on individual machines. Unlike wireless networks that broadcast data through the air, all data packets in a wired network safely travel through Ethernet cables. As long as the router is protected from intrusion using a firewall, your wired home network is safe.

The mobility of wireless networks is overshadowed in some respects by the lower security inherent to wireless. An unsecured wireless network can easily be compromised by a hacker or identity thief looking to intercept private information traveling through your wireless network. Although these risks are very real, many of them can be avoided with proper network installation. For example, using a secure password for logging into the wireless network. Although this does not make a wireless router completely safe, it certainly reduces the likelihood of unwanted guests gaining access to your information.

Summary of The Advantages and Disadvantages

Activity/Category Wireless Network Wired Network
Freedom of movement for users Users can access network from anywhere within range Users location limited by need to use cable and/or connect to a port
Sharing Files Easier with wireless network as you do not need to be cabled to network, though transfer speeds may be slower Generally less convenient as you have to be cabled in, but transfer speeds often faster
Cables Far less complicated, disruptive, and untidy cabling needed Lots of cables and ports needed which can be a headache
Business For businesses dealing with public, customers like and often expect wireless, so wireless can increase income Wired networks are not convenient for public use, but sometimes acceptable for a traditional office
Connection speeds Usually slower than wired Usually faster than wireless
Security Less secure than wired. Both bandwidth and information can sometimes be accessed More secure than wireless
Set up Upgrading to a wireless network can be difficult and expensive Can also be difficult and expensive to set up

Conclusion

Here, we do not mean to abandon one over the other. A good home network will often have both wireless and wired components. Ethernet connections are great for high-speed transfers on desktops or other devices that do not move. Your smart phone, tablet, or laptop will benefit from a wireless network that has been properly configured to ensure a secure browsing experience. Whether you choose a wired or wireless network, or a combination of the two, take time to configure it properly and add a firewall to protect your privacy and the integrity of your network while enjoying the benefits afforded by both technologies. If you need any Ethernet cables for wired network, or cost-effective Ethernet switches for wireless network, just give FS.COM a shot. For more information, please visit www.fs.com.

Why Should Choose Managed Switch Over Unmanged Switch?

Before we talk about managed and unmanaged switch, we should first and foremost figure out what a switch is. Switches are boxes that connect a number of other devices together on a Local Area Network (LAN) and utilize what is called packet switching to effectively forward data to and from connections. Generally, There are two types of switch—managed and unmanaged switch. Here we will discuss the differences between the two types and why managed switch is recommended.

What Is the Difference Between Manged Switch and Unmanaged Switch?

An unmanaged switch on the other hand behaves like a “plug and play” device. It cannot be configured and simply allows the devices to communicate with one another. They tend to be less expensive than managed switches, as they have lower capacity and less flexibility. Generally, they don’t see much use outside of smaller and less intensive networking environments. Managed switches are fully configurable, and can be monitored and adjusted at your discretion. Although the management method and degree of configuration varies, they are typically more expensive than unmanaged switches, but offer much greater flexibility.

difference between managed switch and unmanaged switch

Why Should Choose Managed Switch Over Unmanged Switch?

There are several reasons why a managed switch is recommended.

48 Ports Managed Business Gigabit PoE+ Switch

Remote Access/Control

Managed switches give you better control over your LAN traffic and offer advanced features to control the traffic. Managed switches have all the features of an unmanaged switch and additionally have the ability to configure, manage, and monitor your LAN. So this helps you to monitor and decide who should have access to your network and gives you greater control over data flow through your network.

Security

With a managed switch you can secure your network connections and also protect any unused ports on your switch. For example, if there is an unused port on your managed switch, you can disable that port or even apply MAC address filtering so as not to allow unauthorised users or devices to access the network by just plugging in. Managed switches also require additional authentication through password protection of the network.

Redundancy

Redundancy means to provide an alternate data path to network traffic to safeguard a network in case a connection or cable fails. Managed switches incorporate Spanning Tree Protocol or STP to provide path redundancy in the network. This provides redundant paths but prevents loops that are created by multiple active paths between switches. STP allows one active path at a time between two network devices, prevents loops, and establishes redundant links as backups so that there is lesser downtime. This makes job for a network administrator easier and also proves more profitable for a business.

Quality of Service (QoS)

The Quality of Service (QoS) feature of a managed switch also allows you to prioritize your network traffic by assigning a higher priority to the critical traffic. This helps to improve network performance and helps in better transmission of delay-sensitive data such as real-time voice. So by assigning highest priority to voice data you can ensure the voice packets don’t get dropped or delayed and mangled during transmission and you can hear crystal clear voice during a conversation.

Port Mirroring

Port mirroring is a feature used on managed switches which helps to diagnose network problems. A Managed Switch allows you to configure Port Mirroring to send copies of traffic to a single port on the same switch for analysis by a network analyser. The network analyser then allows you to diagnose and fix problems without taking the network out of service, reducing downtime.

Conclusion

A managed switch is more intelligent and offers more control, flexibility, and features, some you may not even know you need. So if you are still undecided between an unmanaged and a managed switch, then please do not hesitate in getting in touch with FS.COM. We will be more than happy to help with your networking needs.

Layer 3 Switch VS. Router: Which to Choose?

Speaking of layer 3 switch and router, everyone may be confused about the two terms, because they both take IP packets, examine the destination address and pass the packet according to routing rules. It seems that layer 3 switch is identical to a router in this way. Actually, they do have some difference not only in function, but also other aspects. This article will explain how they differ from each other and a better option will be suggested for your reference.

Basics About Layer 3 Switch and Router

In general, a Layer 3 switch (routing switch) is primarily a switch (a Layer-2 device) that has been enhanced or taught some routing (Layer 3) capabilities and it was conceived as a technology to improve on the performance of routers used in large local area networks (LANs) like corporate intranets.

A router is a Layer-3 device that simply does routing only. In the case of a switching router, it is primarily a router that may use switching technology (high-speed ASICs) for speed and performance (as well as also supporting Layer-2 bridging functions).

Comparison Between Layer 3 Switch and Router

Layer 3 Switch VS. Router

Performance versus cost—Layer 3 switches are much more cost effective than routers for delivering high-speed interVLAN routing. High performance routers are typically much more expensive than Layer 3 switches.

Port density—Layer 3 switches, have more higher port count. Routers on the other hand typically have a much lower port density.

Flexibility—Layer 3 switches allow you to mix and match Layer 2 and Layer 3 switching, which means that you can configure a Layer 3 switch to operate as a normal Layer 2 switch, or enable Layer 3 switching as required.

WAN technologies support—Layer 3 Switch is limited to usage over LAN environment where Inter VLAN routing can be performed. However, when it comes to working on WAN and edge technologies, Layer 3 Switch lags behind. Router is the front runner in such scenario where WAN technologies such as Frame Relay or ATM need to be fostered.

Hardware/Software decision making—The key difference between Layer 3 switches and routers lies in the hardware technology used to build the unit. The hardware inside a Layer 3 switch merges that of traditional switches and routers, replacing some of a router’s software logic with hardware to offer better performance in some situations.

Layer 3 Switch & Router: When and Where to Use

Now let’s look into the scenarios when should Layer 3 switch or router be used.

When A Layer 3 Switch is needed?

1. If you need to connect your Hub rooms and make a L3 decision and more Ethernet interfaces are required for direct server form connectivity, then you can use a switch.

2. If you need to connect your inter-offices via l2 circuits by the ISP you can directly terminate the link on the switch and configure routing on the same.

3. If you need more through-put and direct access and interVLAN communication, switch is the best option.

When A Router is Needed?

1. If you are connecting an ISP directly to provide internet, then router is the box you need to deploy.

2. If you need to build tunnels between your offices (connecting 2 offices over public internet securely ), then you need a router.

3. If you are a CE participating in MPLS configuration, then you need a router.

Conclusion

Having explained the mechanism of both a router and a Layer 3 switch, I guess you’ve already have an understanding of them. Simply put, they perform the same function but each have pro’s and con’s as to limitations. Generally, Layer 3 switches are primarily used in the LAN environment, where you need routing. Routers are used in the WAN environment. These days lots of people have started using layer 3 switches in WAN environment, like MPLS.

What Kind of Switches and Patch Cables Should I Choose for SFP Transceiver?

Gigabit Ethernet has supplanted Fast Ethernet in wired local networks and becomes ubiquitous throughout the world, serving as one of the most prevalent enterprise communication standard. The Gigabit Ethernet standard supports a maximum data rate of 1 gigabit per second (Gbps)(1000 Mbps), 10 times faster than Fast Ethernet, yet is compatible with existing Ethernet. To link your switches and routers to a Gigabit Ethernet network, you need a Gigabit Ethernet transceiver as a transmission medium. This article intends to introduce the most commonly used one—SFP transceivers.

sfp

What Is SFP Transceiver?

SFP, short for small form-factor pluggable is a compact, hot-pluggable transceiver used for both telecommunication and data communications applications. SFP transceiver can be regarded as the upgrade version of GBIC module. Unlike GBIC with SC fiber optic interface, SFP module is with LC interface and the main body size of SFP is only about half of GBIC so that it can save more space. SFP interfaces a network device mother board (for a router, switch, media converter or similar devices) to a fiber optic or copper networking cable. It is designed to support SONET, Gigabit Ethernet, Fibre Channel, and other communications standards.

Types & Applications of SFP transceivers

SFP transceivers are available with various transmitter and receiver types, which facilitates users to select the appropriate optical transceiver for different optical reach and optical fiber type (single-mode fiber or multimode fiber) required by different link. SFP transceiver modules can be divided into several different categories:

Types Transmission Medium Wavelength Distance
1000BASE-T SFP Twisted-pair cabling / 100 m
1000BASE-SX SFP Multimode fiber 770-860 nm OM1-275 m/OM2-550 m
1000BASE-LX/LH SFP SMF & MMF 1270-1355 nm MMF-550 m/SMF-5 km
1000BASE-ZX SFP Single mode fiber 1550 nm 70 km
1000BASE-EX SFP Single mode fiber 1310 nm 40 km
1000BASE-BX10 SFP Single mode fiber 1480-1500 nm downstream, 1260-1,360 nm upstream 10 km
CWDM and DWDM SFP Single optical fiber various wavelengths various maximum distances

SFP transceivers are found in Ethernet switches, routers, firewalls and network interface cards. Storage interface cards, also called HBAs or Fibre Channel storage switches, also make use of these modules. Because of their low cost, low profile, and ability to provide a connection to different types of optical fiber, SFP transceiver provides such equipment with enhanced flexibility.
