I believe this question will stump many people, why? Although we are usually exposed to optical communication and optical networks; But you haven't seen the optical module before, have you. Actually. The optical module should be located in places such as optical communication and data centers. So, what exactly is an optical module?
The optical module consists of optoelectronic devices, functional circuits, and optical interfaces. The optoelectronic devices include two parts: emission and reception.
Simply put, the function of an optical module is photoelectric conversion. The transmitting end converts electrical signals into optical signals, which are transmitted through optical fibers. The receiving end then converts the optical signals into electrical signals. And according to packaging classification, optical modules can be divided into XFP optical modules, which are hot swappable, independent of communication protocols, optical transceivers used for 10G bps Ethernet, SONET/SDH, and fiber channel.
