10GbE SFP Switch vs 10GBASE-T Switch: Which Is the Best 10G Network Solution?

As the basis of upgrading network, 10G network has been omnipresent in data center, enterprise network and even home networking. As for two different 10G network solutions: 10GbE SFP switch vs 10GBASE-T switch, which one would be better?

  • Price

The cost reduction of 10GBASE-T technology in the past years has made the usage of SFP+ become an additional expense of adapters for the servers. By contrast, the cost of 10GBASE-T ToR switch is 20% to 40% less than that of SFP+ ToR switch. So 10GBASE-T is much cheaper and provides the most economical solution than SFP+ solution.

  • Backwards Compatibility

10GBASE-T owns the advantage of being an interoperable and standards-based technology that uses the familiar RJ45 connector. It provides backwards compatibility with legacy networks. While SFP switch is limited with little or no backwards compatibility.

  • Power Consumption and Latency

The power consumption of 10GBASE-T switch is 1.5 to 4 Watts per port depending on the distance, while SFP switch uses less power consumption which is typically less than 1 Watts per port. What is more, SFP switch offers better latency with about 0.3 microseconds per link. 10GBASE-T latency is about 2.6 microseconds per link due to more complex encoding schemes within the equipment. With lower power consumption and latency, 10GbE SFP switch is fitted well for large high-speed super-computing applications where latency is a critical factor and high port counts can benefit significant power savings.

Conclusion

When you have to choose between 10GbE SFP switch vs 10GBASE-T switch for the best 10G network solution, the decision should be based on your real need. In general, for equipment that power consumption and lower latency are crucial, a 10Gb SFP switch might be more suitable. However, if cost, flexibility and compatibility are more vital, you may consider a 10GBASE-T switch. Both of them should find an appropriate place in the future of network design and practice.

Understanding Combo SFP Port on Ethernet Switch

For new comers who are not familiar with the structure and functionality of Ethernet switch, they are apt to get confused with different ports built in for different connection. Except for those common ports on SFP switch, such as SFP port , there is another port called “combo SFP port”. Do you know what is it and what is the difference between SFP port and combo SFP port? In this article we aim to give you comprehensive understanding of combo SFP port on Ethernet switch.

What Is Combo SFP Port on Ethernet Switch?

In a nutshell, a combo SFP port is regarded as a single interface with dual front ends, i.e. an RJ-45 connector and an SFP (Small Form Pluggable) module (also called Mini-GBIC) connector. In other words, this is a compound port which can share the same switch fabric, port number and allow the users to configure their SFP switch according to different applications. But the two different physical ports can not be used simultaneously. It means that you can either plug a cable into copper 10/100/1000 interface, or plug the cable into SFP slot.

A combo SFP port is a way to provide different types of connectivity and give users the power and flexibility to configure SFP switch for unique application requirements. Below is the demonstration of 4 combo SFP ports on FS SFP switch.

What Is the Difference Between SFP Port and Combo Port?

Combo interface, also known as optoelectronic multiplexing interface which is a switch device panel with two Ethernet ports: an optical port and an electrical port. Combo electrical port and its corresponding optical port are logically multiplexed, and the user can choose which one to use according to the actual network demand. But when one of the ports is activated, the other port is automatically blocked since they can not be used at the same time.

While SFP port (mini-GBIC port), a small form-factor hot pluggable interface, is designed for high speed and density SFP connection. SFP ports on SFP switch support both copper and optical links. When SFP ports on SFP switch are inserted into SFP modules with electrical ports, Ethernet copper cables are needed for data transmission. If SFP ports are plugged by SFP optical modules with optical ports, then fiber patch cables are required.

Introduction to FS.COM 24 Port Switch With 4 Combo SFP Ports

There are many SFP switches with combo SFP ports, but today we are going to take FS S3800-24F4S: 24 port switch with 4 combo SFP ports as an example to illustrate the usage of combo SFP ports on a SFP switch.

S3800-24F4S 24-port Gigabit switch comes with 20x 100/1000Base SFP, 4x 1GE combo and 4x 10GE SFP+ slots which offers up to 128Gbps switching capacity to synchronously process the traffic on all ports without any packet loss. The 4 combo SFP ports on switch facilitate the application of different connectivity, making it more flexible to configure the switch. In addition, this diversiform port combination form provides a high bandwidth aggregation connectivity for multiple switches to enhance network capacity. All in all, this 24-port Gigabit managed switch is fit for enterprise network operators who pursue high performance and low power processor to provide full speed forwarding and line-dormant capacity.

Conclusion

From the above introduction, we have known that combo SFP port on SFP switch is a port type to carry out different connection applications. For combo SFP ports on Ethernet switch, only one of the twisted pair port or SFP slot can be used. For SFP ports on SFP switch, it can be either plugged into Ethernet copper cable with RJ45 SFP module, or optical fiber cable with fiber SFP module to achieve short and long reach distance transmission. What is more, FS S3800-24F4S is a good example of combo SFP ports on switch. If you have any need, FS would be a choice.

How to Connect Ethernet Switch, Router and Modem

In the computer networking world, the three most ubiquitous pieces of equipment are Ethernet switch, router and modem. These are applied everywhere from data center to network connections in your own home. However, despite the importance of these three pieces of equipment, some people are oblivious or confused to their internal functions and connection mode. So in this article, we will attempt to explain the difference between each piece of equipment and introduce the common way to connect Ethernet switch, router and modem.

What Is the Difference Between Ethernet Switch, Router and Modem

From a physical perspective, a modem, router and Ethernet switch look very similar. Nevertheless, there are key differences between them internally and functionally with relevant purposes on a network.

  • Switch: Bridge Your Devices in a Network

An Ethernet switch is commonly referred to as a multi-port network bridge that processes and routes data on a data link layer (layer 2) and sometimes network layer (layer 3) of the OSI model. An Ethernet switch is an intelligent device which transmits data to specific MAC addresses within the LAN. It has the capability to learn and distinguish between specific addresses by accessing them from a CAM table.

Switch-Bridge Your Devices in a Network

  • Router: Connect You with the Internet

A router is the ”traffic director” of a network. It takes information provided by the modem or ONT and routes it to the various devices that are connected. Router uses protocols such as ICMP (Internet Control Message Protocol) to communicate with each other and configures the best route between any two hosts.

  • Modem: Connect Internet with ISP

A modem is the short way of saying “modulator, demodulator”, which is a hardware device that allows a computer to send and receive data over a telephone line or a cable or satellite connection. The main purpose of a modem when used in a home networking environment is to establish a connection between your home network and ISP.

Connection Between Ethernet Switch, Router and Modem

There are a handful of ways to set up a shareable home network connection, but the safest and most reliable way is to use a router and switch in combination. Once the switch is behind a router (which in most cases uses NAT), all devices connected to either the switch or the router can access the internet simultaneously. Placing the router between modem and Ethernet switch creates an extra layer of protection from threats on the Internet.

Here are the detailed steps for connection:

Step 1: Unplug the power supplies of cable modem, switch and wireless router. Unplug any Ethernet cables that are plugged into any of them.

Step2: Connect telephone wire with modem, and then connect an Ethernet cable to the Ethernet port on the back of the cable modem.

Step3: Plug the other end of Ethernet cable connected with modem into WAN port of router.

Step4: Connect another Ethernet cable to numbered Ethernet port on the switch and plug the other end into the LAN port on the wireless router.

Step5: Plug the power supplies of the modem, Ethernet switch and router in. After two minutes, the network and Internet connection is ready to go.

Connection Between Ethernet Switch, Router and Modem

Conclusion

As you read this, you may be clear about the knowledge of Ethernet switch, router and modem and the proper way to connect them in a network. For suitable Ethernet switch and gigabit switch of good quality, FS would be your great choice.
