Construction Principle of Optical Module
An optical module works at the physical layer of the OSI model and is one of the core components in the fiber communication system. It mainly consists of optoelectronic devices (optical transmitter and optical receiver), functional circuits, and optical bores. Among various optical module form factors, SFP (Small Form-Factor Pluggable). As an important part of fiber-optic communication, an optical module is a photoelectric converter which converts electrical signals into optical signals and vice versa.
