What Is QSFP56 and QSFP56-DD Transceiver Module?

Optical transceiver is one of the most important elements in data centres. Currently, QSFP28 transceiver module is the leading product on the market that supports 40 and 100 Gigabit Ethernet application. However, the world is constantly changing and evolving, new applications such as 4K HD video, webcast, VR and cloud computing have driven a sharp growth of network traffic. Therefore, today, QSFP56 and QSFP56-DD are developed to provide 200G or 400G applications, in order to satisfy people’s higher transmission speed.

Introduction of QSFP

In order to have a good understanding of QSFP56 and QSFP56-DD, we’d better know what QSFP is first. QSFP means Quad Small Form-Factor Pluggable, which is a compact, hot-pluggable transceiver. It’s an industry format that is developed and supported by many network component vendors, and it’s widely used to connect network switch, computer, server, video and some other communication systems. QSFP, QSFP56 and QSFP56-DD transceivers share the same package form, but their transmitting rates are different. This has lead to some other differences such as functions and applications, which will be explained in the following parts.

What Is QSFP56 Transceiver Module?

QSFP56 optical transceiver is the solution for 200G applications. It’s a pluggable transceiver module that has the same size as QSFP. However, this 200G transceiver can provide the top data rate of 50Gb/s of each channel. In addition, products of the transceiver will be compatible with previous QSFP standards. Therefore, the data centres are able to reuse and easily refresh their systems designs and cost in an effective way. Communication specialists forecast that QSFP56 transceivers may accelerate the upgrade of the next generation network switches that the density of their front panel would be doubled, which will create more network throughput. QSFP56 will be the most competitive product due to its powerful processing capacity.


Figure 1: Example of QSFP56 Transceiver Connection

What Is QSFP56-DD Transceiver Module?

QSFP56-DD refers to a double-density QSFP optical transceiver that supports 200Gbps and 400Gbps Ethernet applications. It’s designed to employ eight lanes that operate up to 25Gb/s NRZ modulation or 50Gb/s PAM4 modulation. This means the new 400Gbps optical transceiver will increase the bandwidth and panel density by several times compared to the similarly sized QSFP transceivers. It’s based on the widely applied QSFP interconnection system, which is particularly suitable in data centres and HPC centres. In addition, this transceiver provides backward compatibility to lower-speed QSFP forms, so that when the technicians need to upgrade their networks to a higher speed, they could continue to use the other existing cabling infrastructure.


Figure 2: QSFP-DD vs QSFP


Traffic growth for data centres operators and service suppliers requires the adoption of 200G and 400G optical interfaces in the next generation of network devices. QSFP56 and QSFP56-DD transceiver modules are the best innovations to support customers with high speed and reliable connections. With these optical transceivers, technicians are able to achieve a breakthrough in network transmitting capability. We believe that the applications of QSFP56 and QSFP56-DD are the general trend in the future.

VPLS vs VPWS—How Much Do You Know?

Recently, network virtualisation technology is the most popular and advanced technology both in our daily life and professional fields. There is a wide range of VPN technology available, such as VPLS and VPWS. Based on the use of Ethernet transport, VPLS and VPWS provide high-speed communications. But many business users who are seeking the most cost-efficient and efficient solutions for their network are confused when they face the two technologies VPLS and VPWS. Here focus on VPLS vs VPWS, to unveil their mysteries.

What Is VPLS

Virtual private LAN service (VPLS) is a Layer 2 technology that uses MPLS and VPN to connect different LANs over the Internet. It’s a point to multipoint service that enables geographically isolated sites to be connected through a MAN or a WAN. And all services in a VPLS are on the same LAN. CE and PE are the two basic concepts used in VPLS. CE stands for custom edge, which is the device like a router or a 10gbe switch at the customer premises. PE, the provider edge, is defined as the router at the network of the service provider. It’s typically connected with the CE and responsible for VPN access.

How VPLS Works?

Now let’s look at how VPLS works. In VPLS, first, the packet from a service provider network is sent to a CE device (for example, a 48 port 10gbe switch ). Then, the packet is sent to a PE router. It goes through the service provider network via the MPLS label-switched path. At last, when the packet arrives at the exist PE router, it will forward the traffic to the CE device at the destination customer site. For people who implement VPLS on a data switch, they will enjoy a fast, secure and homogeneous network with lower latency.


Figure 1: Example of VPLS

What Is VPWS?

Virtual private wire service or VPWS is built on MPLS network and provides point to point connections that connect end customer sites in a VPN. It’s also a Layer 2 technology that consists of three main elements, PE routers, Label Distribution Protocol (LDP) and Label Switched Path Tunnel. Unlike the traditional VPNs over Layer 2 circuits, which needs extra separate networks for IP and VPN services, VPWS can share the provider’s core network infrastructure between IP and Layer 2 VPN services. Thus, the cost of these services will be reduced. In addition, a VPWS Layer 2 VPN can be a full mesh or a hub and spoke topology. And MPLS is the tunneling in the core network. But other tunneling protocols like GRE also can be used in VPWS.


Figure 2: Example of VPWS

VPLS vs VPWS: What Are the Differences?

From the above, we can see clearly that the biggest difference of VPLS vs VPWS is that the VPLS provides a point to multipoint servers, while the VPWS provides a point to point service. It means that the CE devices of VPLS and VPWS are different. For VPLS, the CE routers just send all traffic to the PE devices. In contrast, in VPWS, CE routers are used to carry out Layer 2 switching and have to decide which virtual wire could be used to send data to another customer site.


As regard with VPLS vs VPWS, we know they both can build a Layer 2 VPN service to meet today’s high speed network requirement. So don’t be hesitated, use your data switches or routers to set up a safety and efficient VPLS or VPWS service to optimise your network.

What Is DHCP and How It Works

To transmit data back and forth across the Internet, an IP address that administrators have to accomplish and configure on a router or Lay3 fibre switch is the essential cornerstone of a host. Besides, when you want to communicate with other networks, you need to know the default gateway address and subnet mask for the local network, as well as the DNS server. DHCP can help you get all the information dynamically. So what is DHCP and how it works?

What Is DHCP?

DHCP wiki defines the term dynamic host configuration protocol as a network management protocol used on UDP/IP networks. It assigns an IP address and some other configuration parameters to each network device automatically, so that the device will be authorized to communicate with other IP networks. This means users don’t need to configure the network, just plug the wire into your computer or connect to the WiFi, your computer will automatically receive the IP address, subnet mask, default gateway and DNS server. Then how to enable DHCP? DHCP can be installed on a single server or integrated in most network equipment like a Gigabit PoE switch, a router or even the firewall. The following are some related terms we should know.

  • DHCP Client—It obtains an IP address and other parameters from a DHCP server. It is the initiator of an IP address allocation.

  • DHCP Server—It assigns IP address and other parameters to the DHCP client.

  • DHCP Repeater—It forwards DHCP messages between a DHCP server and DHCP clients.

  • DHCP Snooping—It records the users’information that has applied for IP address through the layer 2 equipment.

What Are the Advantages of DHCP?

DHCP protocol reduces the complexity and numbers of administrative work by using automatic TCP/IP configuration. This is the greatest benefit. Today, no matter in the data centre or at home, more and more devices are being networked from printers and fax machines to TV and fridges. Often times, these devices are placed in different locations, without DHCP, you have to get up out of your comfy chair and find the device and configure each manually. But assisted by DHCP protocol, all you need to do is changing the settings on the server or may be a 10gbe switch. As addresses are assigned automatically, there is no need to keep a record of the used and free ones. Besides, DHCP snooping can detect unauthorized DHCP server on the network.

How DHCP Works?

As the title mentions what is DHCP and how it works, now we have learned what DHCP is, let’s turn to its operation. In essence, DHCP leases IP address and other parameters to the specific clients for a period of time. The following picture shows how DHCP works.

What Is DHCP and How It Works

Step one: When a new client wants to join a network, it will broadcast a DHCP discover packet to the servers.

Step two: To answer the request, DHCP servers will send the free DHCP offer packet to the client.

Step three: The client takes the first DHCP offer message from different serves. Then it will send a DHCP request to the Internet to indicate which IP address it has taken.

Step four: DHCP server sends an acknowledge message to make sure the IP address has been used that will not assign to any other client. And now the client can participate on the network.


With regard to the question, what is DHCP and how it works, I think you have found the answer. Any questions of DHCP or network switch supporting DHCP, you can visit FS.COM or contact via

What Is IGMP Snooping

With the development of Internet technology, traditional network unicast mode can’t meet today’s data transmission requirement. On the contrary, this mode increases network load and consuming network bandwidth greatly. IGMP snooping is developed to solve the problem. So what is IGMP snooping?

Introduction of IGMP Snooping

IGMP (Internet Group Management Protocol) is a communications protocol. So what is IGMP used for? Commonly, it’s used to establish membership in a multicast group. And each member host of an IP multicast is a transmitter or receiver.

As for IGMP snooping, which sounds like an obscure hacker technique that may break into one’s network, is actually an advanced option available on most switches or routers. Wiki defines it as the process of listening to IGMP network traffic. It is a multicast constraint mechanism running on the two-layer device, which is used to manage and control the multicast group. If there are plenty of multicast traffic in your network, the whole performance may be affected due to the excessive false flooding. At this moment, the IGMP snooping switch can help to optimize your network. It enables the Gigabit Ethernet switch configured with IGMP snooping decides which devices will receive the applicable multicast traffic, thus the others won’t receive the message. This means the broadcast packet on layer 2 has been reduced so that the network bandwidth will be conserved. Besides, IGMP snooping helps improve message information.

IGMP Snooping Process

After knowing what is IGMP snooping, let’s see how it works. Once a device joined the multicast group, the router or fiber switch will notice this. Then the message cab forwarded to the devices that have joined the multicast group. Look at Figure 1, when the switch runs without IGMP snooping, the multicast packet will be transmitted to host A, B, and C. But when the switch has set up IGMP snooping, only multicast group members host A and C can receive the multicast packet. This is the main IGMP snooping tutorial.

What Is IGMP Snooping

Figure 1: The picture shows how IGMP works.

Using FS.COM Switch to Build IGMP Snooping 

To keep pace with technology development, FS.COM releases a set of switches to help customers establish IGMP snooping. Here is a 24 port switch named S3900-24T4S. The fanless 24-port 10/100/1000BASE-T Gigabit stackable managed switch provides an affordable solution for business of all sizes requiring switches with essential L2 switching features like VLAN and IGMP snooping, along with a simple and intuitive management interface.

Ethernet switch

Figure 2: S3900-24T4S 24 Port Switch


Now I think you know the answer to the question we posed at first, what is IGMP snooping. When IGMP snooping is enabled, the bandwidth consumption will be reduced in a multi-access LAN environment so as to avoid flooding the entire VLAN. Any question about IGMP snooping configuration, please contact us via

How to Use a PoE Injector to Install an IP Camera?

Are you looking for a solution to easily power your IP cameras? It’s no doubt to use a PoE injector or Gigabit PoE switch to complete the installation. Once your system is established, you can view your home circumstance from your computer or smartphone from anywhere. Here focus on how to use a PoE injector to install an IP camera.

What Does a PoE Injector Do?

Power over Ethernet is commonly regarded as PoE for short. It’s a technology that can transfer both power and data over twisted pair Ethernet cables such as Cat5e, Cat6, etc. A Poe injector is a device that is commonly known as the “midspan”. It supplies power to a camera by delivering power into the Ethernet cable. Usually, a power over Ethernet injector converts the alternating current into direct current so it can be the power supplier for low voltage IP camera.

What Does an IP Camera Do?

Unlike the traditional cameras, IP cameras can send and receive data over a LAN or the Internet. It’s a separated unit with its own IP address that needs nothing but a network connection like WiFi or PoE injector switch. IP cameras capture images just like a digital camera, and compress the files for transmission over the network. So these images can be viewed anywhere in the world. Also, this camera can be controlled remotely.

How to Use a PoE Injector to Install an IP Camera


Before the installation, we should prepare a PoE injector, IP camera and Cat5e cables. Here, we will choose the products, single port 10/100/1000M Gigabit PoE injector, 3MP indoor/outdoor dome IP camera with infrared from FS.COM as an example.

  • Single port 10/100/1000M Gigabit PoE injector fully complies with IEEE 802.3af. It has two RJ45Ethernet ports, one is labeled Data In and one is labeled PoE/Data Out. With a power supply of 15.4W, this PoE injector for IP camera delivers power up to 100 meters. No configuration is required, just plug and play.

PoE injector

Figure 1: Example of PoE injector

  • 3MP indoor/outdoor dome IP camera with infrared is a professional surveillance and security solution for houses and enterprises. It provides video resolution of 2065×1553 pixels over a digital signal using Cat5e or Cat6, and observe high quality footage with the advanced SONY starvis back-illuminated CMOS sensor.

IP camera

Figure 2: Example of IP camera


First, check the equipment, make sure the PoE injector and IP camera are in good condition. Besides, turn off the devices’ power for safe installation.

Second, plug one end of Cat5e cable into the PoE injector’s PoE/Data out port, and the other end into IP camera’s PoE port.

Third, choose a place to mount IP camera. Usually, the dome IP camera is installed on the roof corner that is adequate to capture the faces of subjects of different heights.

Fourth, use another Cat5e cable to connect PoE injector and a fibre switch.

Last, make sure all connection is correct. Then plug in power to ensure all connections are working normally.


The installation just requires several devices, a PoE injector, an IP camera, a non-PoE switch and some cables, or you can use a PoE switch like 24 port PoE switch to replace the PoE injector. Well, no matter which way you will choose to install your IP cameras, FS.COM is the one-stop shopping base when you need to buy these network devices.

Understanding the Two Terms: EVPN vs VXLAN

EVPN vs VXLAN is one of the most popular network technology. They were developed because enterprises need to deliver data and share resources at different geographical locations. Therefore, the efficient, reliable and high speed interconnection is required for the different sites. EVPN vs VXLAN are born as the new upcoming technology to meet today’s network demands.

Introduction of EVPN vs VXLAN

What Is EVPN

EVPN or Ethernet VPN, is regarded as a next generation all-in-one VPN technology. It offers Ethernet multipoint services over MPLS (multiple protocol label switching) or IP networks. Using EVPN service and with the help of MPLS core network, users can connect the offices located in different areas via the lay 2 network for sending messages. This is similar to the work that extends LAN to WAN. Also, it greatly reduces the difficulty of network deployment and maintenance. In addition, EVPN supports MPLS, VXLAN, and other data plane encapsulations.


Figure 1: Example of EVPN


VXLAN is short for Virtual Extensible LAN. As the name implies, we know this technology is designed to provide the same transmission service for Ethernet connection that VLAN do today, but in a more extensible way. Technologically, VXLAN is a MAC in IP/UDP encapsulation technique with a 24 bit segment identifier in the form of a VXLAN ID, which is larger than the LAN with 12 bit segment ID. Also, it supplies a way to span Layer 3 network by VXLAN tunnel that is established between VETP (VXLAN Tunnel End Point). Thus it has a higher scalability to address more Layer segments.


Figure 2: Example of VXLAN

Route VXLAN with EVPN

EVPN vs VXLAN are both virtual technology. VXLAN explained that EVPN could be the control plane of VXLAN, which uses the BGP (Border Gateway Protocol) to provide high scale, multi-tenant separation and fast convergence for host and VM mobility. So EVPN helps us to deploy VXLAN tunnels without controllers. Routing VXLAN is available in two architectures—centralized or distributed. Compare these two approaches, it’s clear that the distributed architecture will simplify the traffic flow. And here is the place for routing VXLAN with EVPN according to VXLAN tutorial.

For the distributed architecture, asymmetric IRB (integrated routing and bridging) and symmetric IRB are the two models to achieve inter-subnet routing with EVPN. Both of them are valuable, so choose the suitable model for your legacy network system.

FS.COM Solution for EVPN vs VXLAN

FS.COM S5850 series switches are designed for hardware based VXLAN function. The following is a 10gb Ethernet switch from FS.COM.

This S5850-48S6Q is a Layer 3 switch. This fibre switch has an advanced architectural design with 48 port 10G SFP+ and 6 port 40G QSFP+ in a compact 1U form factor. It can provide extensive data centre service features and switching capacity of 1.44Tbps. Besides, the wind direction of the switch is front-to-back, or you can change it to back-to-front. With support for advanced features, including MLAG, VXLAN, IPv4/IPv6, SFLOW and so on, this switch can help enterprises to build a scalable data centre network platform in the cloud computing era.


Figure 3: S5850-48S6Q Switch


From the above, we have a better understanding of EVPN vs VXLAN. FS.COM, as an excellent provider of enterprises solutions, offers different kinds of switch such as PoE network switch, SDN switch to satisfy customers’ various network demand.

How to Choose 24 Port Patch Panel

And all the patch panels can provide a simple, neat and easily managed solution for IT technicians. Today, we’ll focus on 24 port patch panel buying guide.

Why We Use 24 Port Patch Panel

As we know, using a patch panel can enjoy many benefits. It can reduce cable congestion, improve flexibility and scalability and save the valuable space in a sever rack. These contribute to the simplification of manual monitoring, testing, routing and other maintenance on cables. Besides, the  24 port patch panel price is more favorable than other patch panel types. And designed in the same size, the ports distances of 24 port type is not as compact as the 48 port or 96 port ones, which is better for cable connections and cable cooling. This encourages people to choose 24 port type instead of the others.

24 Port Patch Panel: Copper or Fibre

As the backbone of a structured cabling solution, patch panels are available in copper and fibre versions. They are designed to connect different cables. Copper patch panel are used to connect the specific cables like Cat5, Cat5e or Cat6, while fibre patch panel is only applicable for single mode or multimode fibre cables with LC, SC connectors. Thus, before we buy 24 port patch panel, we must know what type of cables that used in our network.

What Is Open Frame Rack and How to Use It?

There are many different types of server racks on the market, like open frame rack, server cabinet, and rack mount and wall mount enclosures. Open frame rack, thanks to its reasonable price, and material saving, has attracted more and more customers. It is more convenient to ship and be packed. To help you better understand the open frame rack, this article will introduce it in three aspects.

Brief Introduction of Open Frame Rack

The open frame rack is an equipment to mount your servers and other network equipment. When you deploy equipment and organize cables in a computer room or data centre,it is important to make proper and reasonable space utilization. Therefore, open frame server racks come at a right time to help stay organized in a cost-effective manner. Here I list four benefits of open frame server racks and why you should consider them for you equipment storage needs.

2-post open frame rack

Benefits of Open Frame Rack

Better Cable Management

The fact that you may run the cables with obstacles from doors and panels won’t frustrate you when using an open frame rack. It is just formed by 2-post racks or 4-post racks with no limitations to each orientation. With this rack, you will not consider whether it can contain all your applications within the space any more.


The enclosed racks are not easy for ventilation. Open frame server racks, on the other hand, allow for unrestricted airflow, preventing heat build-up. The proper cooling is conducive to the running of the whole system.

Easy Access

Without barriers, you can access to every equipment and route cables freely in every direction you want. And all the organs and working status are visible to you for real-time monitoring.


Open frame server racks are a cost-effective way to manage equipment, compared to enclosed racks. For example, the 45U 4 post open frame server rack sells at $300 and 2 post one $210, much cheaper than the 45U server cabinet selling at $650. The cost of producing and shipping is less than those of closed cabinet or server racks.

How to Use Open Frame Rack?

Take the FS.COM 45U 2 post open frame rack as an example, there are many mounting holes on the two posts on which you can attach different devices like cable organizer and patch panel rack in 19’’ standard. You’d better put it on the flat ground lest it fall down.

SDN vs NFV: What Is the Difference?

SDN and NFV that have emerged in recent years, are the most aggressive technology in the networking industry. SDN NFV are born to provide new ways to design, build and operate networks. What is SDN? What is NFV? SDN vs NFV, what’s the difference? Here talks about SDN and NFV.


Figure 1: SDN and NFV

SDN vs NFV—Definition

What Is SDN

SDN, software defined networking, started from the campus network. It developed to solve the network issue that people had to change the software of their devices when they tried to deploy a new protocol. SDN is a telecommunication revolution that separates the control plane of a network from the data plane that forwards one’s network traffic, aiming at creating a centrally managed and programmable network. As an innovative architecture of new network, it provides a way to implement network virtualisation.

What Is NFV

NFV, network function virtualisation, is developed by dozens of large telecommunication service providers. Often times, it’s difficult for them to accelerate the implement of new network services due to the restrictions of hardware-based appliances. Thus, the goal of NFV is to virtualize the network services such as DNS, caching, etc., and abstract them from the hardware on which they run, and hence they can run in software. NFV is a disruptive technological reform that offers a more open and flexible service deployment for telecom operators’ network architecture.

SDN vs NFV—Difference

From the above, we know SDN and NFV rely on virtualisation so that the network design and infrastructure can be abstracted in software. But do you know the difference of SDN vs NFV?

SDN vs NFV example

Figure 2: SDN vs NFV

Basically, SDN abstracts physical devices like data switch or router and makes the controller process to a virtual network control plane. In this way, the virtual control plane will decide the locations for sending traffic. By contrast, NFV is designed to use the standard x86 server to replace the dedicated network devices like the firewall. As a result, the network function is independent from the dedicated devices, which enables the network to develop without extra devices. The table below shows the differences between SDN and NFV.

Basic idea
Separate control and data.
Transfer network functions from dedicated applications to generic servers.
Initial application target
Cloud orchestration and networking
Firewalls, gateways, WAN, CDN, etc.
Open flow


Supporting organisation
Open networking foundation
ETSI NFV working group

SDN vs NFV—Future Outlook

Since SDN and NFV share the same aims that improve software-based  approaches to create more flexible, scalable and perfect networks to support the increasing business demand, they have become popular in the network industry. And there’s no doubt that SDN and NFV will work together with traditional switches or some other optical equipment in the future. To follow the technological trend, FS.COM has developed SDN switches to satisfy customers’ various needs.

The N5850-48S6Q SDN switch offers 48 SFP+ 10GbE ports and 6 QSFP+ 40GbE ports that support non-blocking exchange. It adopts 1.44Tbps full-duplex switch capability with the operating system of broadcom ICOS, creating a more open installation environment for users. Compared with the traditional switch, this SDN switch separates the data path from the control path, which helps to make a high-level routing decision.

Figure 3: SDN Switch


As regard to SDN vs NFV, we have learned the basic information of them. Also, we recognize that SDN and NFV will make a difference in the future. FS.COM, the supplier of switches such as 10gb switch, 40GbE switch and even 100GbE switch, will keep pace with the innovations of network world.

How to Choose a 48 Port Patch Panel?

Patch panel, the critical component in the data centre, comes in various types. The port density of a patch panel may not be your primary consideration, but it indeed matters as the ports directly affects the cable management needs either at present or in the future. The number of these ports vary from 12, 24, 48, 64, 72, 96 to 288 and even more. Actually there is no limit to the number of ports on a patch panel. In this article, I’d like to share a buying guide about 48 port patch panel.

48 Port Patch Panel: Copper VS. Fibre

No matter how many ports they have, patch panels can be deployed in fibre and copper cabling system to organize and distribute cables. The 48 port patch panel is no exception. There is no practical difference in performance as the role of patch panels is to direct signal traffic rather than send the signal. However, there is indeed a difference between the cables they will wire. Fibre patch panel is mainly used in fibre optic cable management, while copper patch panel is designed for both shielded and unshielded copper cables like Cat5e, Cat6, Cat6a, and Cat7.

Copper 48 Port Patch Panel Recommendation

As for the copper patch panel, it is designed according to the copper cable types. Sometimes, Cat5e, Cat6 or other Ethernet cables need to be managed in a single panel. In this situation, the blank keystone patch panels can support mixed cabling with installation of different rj45 insert modules. The 48 ports blank keystone/multimedia patch panel, manufactured by FS.COM, is made of SPCC CRS material. It can accommodate all keystone jacks, including RJ45 Ethernet, HDMI audio/video, voice and USB applications. In addition, the high density 19in wide, 1U High, panel design will save valuable space in the rack. With it, you can customize your patch panel according to your specific application.

copper 48 port patch panel

Fibre 48 Port Patch Panel Recommendation

When it comes to 48 port fibre patch panel, you can choose it based on your fibre core, single mode or multimode. 1U 19″ high-density fibre patch panel(ID:69082) can accommodate up to 96 fibres with 48 ports on it. As a fibre patch panel, it supports the OM3/OM4 multimode fibre mode. Designed with LC duplex on both sides, it saves much cost as being fully loaded with fibre couplers. Specifically, FS.COM comes up with an innovative design and cable management. The 1U detachable horizontal cable management panel can protect and organize fibre optic cable in your network.

fiber 48 port patch panel

Roughly the same with the former fibre patch panel, this one, 96 fibres, 48 ports LC 9/125 single mode adapters, 1U 19″ high-density fibre patch panel, supports OS2 9/125μm single mode fibre.
