XFP Module VS SFP Module


Technical stuff really gives us a hard time understanding what they are. Though most of us are not technician, we still want to understand the latest trends of our time. 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. 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.
XFP module also called XFP transceiver and what is an XFP module? "XFP" stands for "10 Gigabit Small Form Factor Pluggable." With XFP you will surely experience a fast transmission of data in your computer network including your telecommunication links.
According to Wikipedia, XFP is a hot-swappable and protocol independent module. It means that you can replace the component without shutting down the whole system. XFP can replaced without interrupting the operation of your system. Its usual operation is at optical wavelengths of 850nm, 1310nm, or 1550nm. To be able to install this module in your computer, you should have one of these: 10 Gigabit Ethernet, 10 Gbit/s Fibre Channel, Synchronous Optical Networking at OC-192 rates, Synchronous Optical Networking STM-64, 10 Gbit/s Optical Transport Network OTU-2, and parallel optics links. XFP modules are able to function with just a single wavelength or dense wavelength division multiplexing techniques.
“SFP” stands for “Small Form-factor Pluggable.” It is a compact, hot-pluggable transceiver used for both telecommunication and data communication applications. It interfaces a network device mother board (for a switch, router, media converter or similar device) to a fiber optic orcopper networking cable. It is a popular industry format jointly developed and supported by many network component vendors. SFP transceivers are designed to support SONET, Gigabit Ethernet, Fibre Channel, and other communications standards. Due to its smaller size, SFP obsoletes the formerly ubiquitous Gigabit interface converter (GBIC); the SFP is sometimes, erroneously, referred to as a ‘Mini-GBIC’ (although no such device has ever been defined in the MSAs).
