Speaking of PON optical modules, let's first understand what PON is. Generally speaking, PON refers to a passive optical fiber network, which is an important way for broadband access network services to be carried. PON technology originated in 1995. Later, according to the difference between the data link layer and the physical layer, PON technology was gradually subdivided into APON, EPON, and GP...
