What is the difference between SFP optical module and GBIC optical modules?Where to buy sfp optical modules ?

In optical module market there are many different types, different types of optic module to meet the needs of different users, these modules demand collaboration with all kinds of transmitters and receivers. Therefore, in order to ensure that each link can be suitable for optical fiber type (single mode fiber or many optical fiber) supply reliable fiber channel, the user needs to choose the suitable optical module. In addition, according to different types of module interface, SFP and GBIC module also has many types, such as base - 1000 SX, base - 1000 LX/LH, bas - EX 1000 or 1000 base-t, etc.

GBIC and just an differences between SFP optical module that is smaller than light module GBIC SFP optical module. Due to the small size of SFP (volume is almost just half the GBIC module light), we can double port on the same panel equipment, increase the utilization rate of the switch/router. SFP optical modules and the fundamental function and the function module GBIC light are almost the same. Although there are still users use cannot be advanced to update using SFP optical module only support module GBIC light of old equipment, but these devices will gradually be selected and replaced by support the SFP optical module device.
