What are SFP and XFP Connectors?

 

What is SFP?

SFP, short for Small Form-Factor Pluggable, is a compact, hot-pluggable optical module used in telecommunications and data communication applications. SFP optical modules can be seen as an upgraded version of GBIC modules. Unlike GBIC modules that have an SC fiber interface, SFP modules feature an LC interface and have a form factor roughly half the size of GBIC, allowing for space savings. SFP modules connect the motherboard of network devices such as routers, switches, media converters, or similar equipment to fiber or copper cables. Additionally, SFP is a widely adopted industrial specification supported by numerous networking equipment vendors. It is designed to support SONET, Gigabit Ethernet, fiber channel, and other communication standards.
It is designed for hot-plugging and is an internationally standardized interchangeable product. Gigabit Ethernet switches designed with GBIC interfaces have gained a significant market share due to their flexibility. SFP (Small Form-factor Pluggable) can be simply understood as an upgraded version of GBIC.
 

What is XFP?

XFP (10 Gigabit Small Form Factor Pluggable) is a hot-pluggable, protocol-independent optical transceiver typically operating at wavelengths of 850nm, 1310nm, or 1550nm, used in 10Gbps SONET/SDH, fiber channel, gigabit Ethernet, 10 gigabit Ethernet, and other applications, including DWDM links. XFP includes a digital diagnostics module similar to SFF-8472 but expanded to provide robust management tools.
XFP, short for 10 Gigabit Small Form Factor Pluggable, is a standard optical module used in high-speed computer networks and telecom links for communication over optical fibers. The XFP standard, as well as its interface with other electronic components, was defined by an industry group in 2002. XFP optical modules are hot-pluggable I/O devices that are inserted into 10 Gigabit ports. XFP modules connect system circuits to optical networks.
The XFP package is smaller than the earlier XENPAK and X2 packages but slightly larger than the original Small Form-Factor Pluggable (SFP) modules.
 

XFP vs SFP

Technical stuff really gives us a hard time understanding what they are. Though most of us are not tech savvy, we still try to understand the latest trends of our time. You think you want to get one yourself but didn’t know exactly why you needed one. This includes owning a computer. If you have noticed, the development and growth of computers has increased tremendously. Every day we hear a lot about computer updates. This may be through the television or even through the Internet. The generation of today seems like tech robots. We don’t know whether the minds of people today are now made of wires and plugs since they are able to catch up with the ongoing changes of the tech world.

Even in the line of telecommunications it has developed progressively. There are a lot of transceivers being produced to increase your signal. A transceiver is a package with a transmitter and a receiver. It all comes in one. Transceivers are essential for wireless communication devices. Our cellphones, cordless telephones, and handy, two-way radios have transceivers installed.

To be able to transmit data, we need transceivers. The most common way of transmitting data is to use light-based fiber optics. The use of electronic signals is the traditional and slower way of transmitting data. The best modules to use today are the XFP and SFP modules. These modules are your greatest solutions in having a greater quality signal delivered to your home. Aside from that, they are also cost-effective.
