SFP (which is half the size of the GBIC module and can be configured with more than double the number of ports on the same panel. Since the SFP is basically the same as the GBIC function, SFP it is also known by some switch manufacturers as miniaturized GBIC (Mini-GBIC ).
SFP compresses the size and power consumption by placing CDR and electro-dispersion compensation outside the module. For optical communications applications in telecommunications and data communications. SFP network equipment such as switches, routers and other equipment, SFP motherboards and fiber or UTP cable. SFP is an industrial specification SFP + fiber module supported by some fiber device vendors, (10 Gigabit Small Form Factor Pluggable
) Is a hot-swappable optical transceiver independent of the communication protocol. Usually the wavelength of the transmitted light is 850 nm, 1310 nm or 1550 nm, for SONG / SDH of 10 G bps
Fiber Channel, gigabit Ethernet, 10 gigabit Ethernet, and other applications also include DWDM links. The XFP contains a digital diagnostic module similar to SFF-8472, SFP but has been extended to provide a powerful diagnostic tool.
SFP type SFP + supports SONET, Gigabit Ethernet, Fiber Channel, and some other communication standards. This standard extends to SFP + and supports 10.0 Gbit / s transfer rates, SFP including 8 gigabit Fiber Channel and 10GbE. Introduced the fiber and copper version of the SFP + module version, with the module Xenpak, X2
Or XFP version, the SFP + module will be part of the circuit to stay on the motherboard implementation, rather than within the module.
SFP is an abbreviation for Small Form-Factor Pluggable and can be easily understood as an upgraded version of GBIC. SFP volume is less than half the GBIC module, SFP and more than twice the number of ports can be configured on the same panel. SFP's other features are basically the same as GBIC. Some switch manufacturers said SFP for small GBIC (MINI-GBIC), support SX, LX, TX, LH, take 1000M.
SFP: is the interface device that converts gigabit electrical signals into optical signals.
Designed for hot swap. Is an interchangeable product that conforms to international standards. Gigabit switch with GBIC interface design because of the exchange of flexible, SFP in the market occupies a larger market share. SFP (Small Form-factor Pluggable) can be easily understood as an upgraded version of GBIC.
