GBIC modules are divided into two categories: first, GBIC modules that are commonly used in cascading to achieve common connections with other switches; The second is to stack dedicated GBIC modules to achieve redundant connections with other switches.
GBIC has been basically replaced by SFP for the following reasons:
SFP (Small Form Pluggable) can be simply understood as an upgraded version of GBIC.
SFP modules (with a volume reduced by half compared to GBIC modules) can be configured with more than twice the number of ports on the same panel.
Due to the basic consistency between SFP modules and GBIC in terms of functionality, it is also referred to as Mini-GBIC by some switch manufacturers.
The SFP module compresses size and power consumption by placing CDR and electrical dispersion compensation outside the module. Used for optical communication applications in telecommunications and data communication. SFP connects the motherboard and fiber optic or UTP cables of network devices such as switches and routers. SFP is an industrial specification supported by some fiber optic device providers
SFP supports SONET, Gigabit Ethernet, Fiber Channel, and some other communication standards. This standard extends to SFP+and can support a transmission rate of 10.0 Gbit/s, including 8 gigabit fiber channel and 10GbE. The SFP+module version introduces fiber optic and copper core versions. Compared to the Xenpak, X2, or XFP versions of the module, the SFP+module leaves some of the circuits implemented on the motherboard rather than within the module.
