Nowadays, with the prevalence of 5G, optical modules are also developing rapidly, ranging from 155m, 1.25G, 8G, 10G, 25G, 40G to 100G. The higher the speed, the higher the price of the optical module, if only applied to Gigabit ethernet, there is no need to buy a higher rate. SFP optical module is widely used in Ethernet because of its small size, low cost and high density. So what are the types of common Gigabit SFP optical modules?

Four common Gigabit SFP dual-fiber modules:

In order to better distinguish 1.25G SX, 1.25G LX, 1.25G EX and 1.25G ZX optical modules, the comparison tables of these optical modules are listed in the following table.
