What is Gigabit Module

In the era of relative development of network data at the speed of light, there is a kind of network-related equipment: optical module is also developing rapidly to meet the progress of the market. The optical modules are divided into high and low speed ones. The low speed ones are generally 100G modules, gigabit modules and 10G modules, while the high speed ones are 100G modules, 200G modules and 400G modules. The price of optical modules also varies with the type of light speed. Modules are used differently in different scenarios. If they are used in gigabit Ethernet transceivers, gigabit optical modules need to be used for matching.

At present, our communication optical module/optical communication module/multimode optical fiber module are all our hot products. If you want to know more about the technical knowledge of the combination of modules and switches, please return to the home page and contact us!

The gigabit optical module mentioned above refers to the optical module with a transmission rate of 1.25Gbps, which generally has two packages: SFP and GBIC. The common package is SFP package. Because the volume is half smaller than GBIC module, other functions are basically the same as GBIC. It can be simply understood as the upgraded version of GBIC, and the transmission distance can also reach 80-160km. Gigabit optical module is used in Gigabit Ethernet transceiver, and is also the most widely used optical module in small and medium-sized data centers in the market.
