FE for 100M GE for Gigabit.

FE stands for Fast Ethernet, also known as 100M Ethernet. Fast Ethernet, also known as 100 Gigabit Ethernet, is similar to GE (Gigabit Ethernet interface).

GE interface, refers to Gigabit Ethernet Gigabit Ethernet interface, the interface with the GE marking, indicating that it is a 1000M Ethernet network interface;

SFP is a 100Gigabit or Gigabit module, which is divided into multi-mode module and single-mode module, and in the single-mode module is divided into transmission distance of 10KM, 40KM, 80KM and other models;

FE means 100 Gigabit, GE means Gigabit, 10G means 10 Gigabit; FE and GE are SFP, 10G is XFP.

Extended Information:

Gigabit switches designed with GBIC interfaces have a large market share due to their interchangeability.SFP (Small Form-factor Pluggable) can be simply understood as an upgraded version of GBIC.

SFP (Small Form-factor Pluggables) can be simply understood as an upgraded version of GBIC. the SFP module (half the size of the GBIC module) can be configured with more than double the number of ports on the same panel. Since SFP modules are basically the same as GBICs in terms of functionality, they are also referred to as miniaturized GBICs (Mini-GBICs) by some switch vendors.

SFP modules, on the other hand, are even more compressed in size and power consumption by placing the CDR and electrical dispersion compensation on the outside of the module. Used for optical communication applications in telecom and datacom, SFP connects the motherboards of network devices such as switches and routers to fiber optic or UTP cables.SFP is an industry specification supported by a number of fiber optic device providers.

SFP supports SONET, Gigabit Ethernet, Fiber Channel, and a number of other communication standards. The standard was extended to SFP+, which supports 10.0 Gbit/s transmission rates, including 8 gigabit Fiber Channel and 10GbE.

Fiber and copper versions of the SFP+ module were introduced, and in contrast to the Xenpak, X2, or XFP versions of the module, the SFP+ module leaves some of the circuitry on the motherboard implementation instead of implementing it within the module.
