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.

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.

Selection Guide on PoE Switch

Currently IP cameras are widely used for video surveillance due to the high requirements for security. Typically, the IP cameras are with PoE functions, then PoE switch is needed for the connection. But some users feel confused about the PoE switch and don’t know how to choose a suitable PoE switch. This article is going to introduce you some guides on PoE switch selection.

What Is PoE and PoE Switch?

PoE is short for power over Ethernet. With PoE technology, data and power can be transmitted over a single Cat5e cable. A PoE switch is a device that contains multiple Ethernet ports to provide power and network communications to IP cameras. PoE switch is an economical and reliable solution for small business networks to deploy wireless access points and IP surveillance cameras.

Considerations for PoE Switch Selection
Numbers of Ports

The most important is to check whether the numbers of ports on PoE switch are enough to connect all your devices. Fiberstore offers PoE switches including 8 ports, 24 ports, and 48 ports. PoE ports are flexible to connect with Cat5e cable without additional settings. All of our PoE switches have 2 Gigabit uplink SFP ports or 4 SFP+ ports. Uplink ports allow long distance data transmission between switches. With these ports, you can easily expand your networks. (Check news about PoE switch from FS.COM: Build and Expand Your Network with FS.COM New Introduced PoE Switches) So if you need to link multiple switches, you need to select switches with enough Gigabit ports.

Power Supplies for Powered Device

PoE switch applies two standards: IEEE802.3af and 802.3at. Each one can offer power for IP cameras. Due to the different standards, the output power of PoE switch is also different. IEEE802.3af can provide 15.4watts DC power on each port. As some power dissipates in the cable, only 12.95watts power at most can be supplied to powered devices. This standard is enough to power VoIP phones, wireless access points and some cameras over standard Ethernet cabling. While, IEEE802.3at is updated PoE standard known as PoE+. It can provide up to 25.5watts power available for powered device which is nearly twice as many as that 802.3af supplies. The updated standard can support more devices with high-power functionality such as door controllers, cameras with zoom capacity, or wireless access points supporting 802.11n.

Total Power

PoE switch has a total power. As described before, under IEEE802.3af standard, each port on the PoE switch can get 15.4watts power. Thus, the total power of a 24-port switch must reach 370watts so that it can make sure each port get sufficient power. And make sure there is additional power beyond that required for PoE for its switching functions. As to the IEE802.3at standard, each port supports 30watts. Under this condition, the PoE switch with total power of 370watts can only provide power supply to 12 ports.

Cable Requirements

The DC power of IEEE 802.3af standard is 15.4watts. It can support 10BASE-T and 100BASE-T. Two of four twisted pairs of Cat3 cable or higher can support the power and data transmission. The PoE+ standard delivers power up to 30watts and supports 1000BASE-T. Cat5e or Cat6 cable is able to support the power transmission. Connecting PoE switch to the router or cameras with Cat5e or Cat6 cable, the maximum transmission length is up to 100 meters.

When buying Ethernet cables, find a reliable vendor who provides standard network cable meeting the strict requirement. PoE power supply must use oxygen-free copper material—standard network cable. Non-standard cable utilizes other materials such as copper clad steel, copper clad aluminum, copper coated iron, etc. These cables are not suitable for PoE power supply because of the big resistance.

Conclusion

PoE switch is a cost-effective solution to increase the reliability and security of networks by providing centralized backup power to all connected IP surveillance devices. Before purchasing PoE switches, try to know as more details about the switch specifications as possible and also your own needs. To get good quality PoE switches, please come to FS.COM.

Which Ethernet Cable Should You Choose?

Ethernet cable is one of the media transmitting signals to a home or business network place. Although the world is going wireless today, Ethernet cable is still used in many situations due to its advantages of fast speed, high reliability and security. But when you decide to buy the Ethernet cables, you will get confused about which category to choose. This article will discuss how to make your decision among these Ethernet cables like Cat5, Cat5e, Cat6 and Cat7.

Ethernet Cables Types
Cat5 Cable

Cat5 cable can handle 10/100 Mbps speed (Fast Ethernet) at the bandwidth up to 100 MHz. Cat5 cable is the oldest of these three kinds of cables. Over the years, Cat5 cable was used majorly in networking especially when pairing older routers, switches and other myriad networking devices. Nowadays it’s not used for too many installations. But it can support gigabit speeds if the cable is shorter sometimes.

The letter “e” means “enhanced”. As the name says, Cat5e is an improvement on Cat5 cable. Currently it’s the most popular cable used in new installations. It’s designed to support 1000 Mbps or gigabit speed. It can also greatly reduce the crosstalk. The crosstalk is the interference existing sometimes between wires that are sealed inside a cable. With this feature, Cat5e can better keep signals on different circuits or channels from interfering with each other. In a word, Cat5e cable can provide a faster, more reliable and steady network than Cat5. And Cat5e is also compatible with Cat5 cable.

Cat6 is an improvement over Cat5e. It has more sophisticated constructure and can support the speed up to 10 gigabit and the bandwidth up to 550 MHz over long distances. Cat6 is a good choice for those who want to install future-proof network. But Cat6 cable is not very good for the applications at home. This kind of cable is recommended for large organizations which deal with pretty bulk files.

cat6

Cat7 cable is designed to be used in Gigabit Ethernet and can support bandwidth up to 600 MHz. It greatly improves the capacity and reliability of Cat6. Another big advantage of Cat7 is the shielding of its twisted pairs, which significantly improves noise resistance. Cat7 is thought as the most durable and has a longer lifespan than Cat 5 and Cat 6. It’s the best choice for future use. But it’s comparatively expensive.

Which One Should You Choose?

First, you need to think about the question seriously how you like your current network speed. If you are satisfied with the current network speed, you don’t need to upgrade it. But if your hardware can handle 1 Gigabit and you are still using Cat5 cable, then you should better upgrade your Ethernet cables. You may choose Cat5e cable which is enough for your network needs. Or you can select Cat6 cable.

Second, you should know that network speed is not the same to internet speed. There is a chance that even though you upgrade your Ethernet cable, your internet speed won’t change too much. As it’s affected by many other factors. However, upgrading networking cables have a tremendous effect on file transfer speeds between computers. So to emphasize, when buying Ethernet cable, you should also consider your hardware compatibility.

Conclusion

From this article, you can find it’s not very hard to decide which kind of Ethernet cable to use. To make the right decision, it depends on your situations. Usually Cat5 or Cat5e cable is enough for home network use. If you transfer lots of data over your network, then you can upgrade your network cables from Cat5 to Cat5e or Cat6 to guarantee your network speed. But if you are satisfied with your current network speed, you don’t need to replace Cat5 with other cables. Of course, the cost is also an important factor. So if budget allows, Cat7 is a nice choice. At last, no matter what kind of cable, please notice that the Ethernet cable should be less than 100 meters in length to achieve higher efficiency.
