Many consumers are confused about the product of optical modules, because there are many opportunities for contact, although we usually come into contact with optical communication and optical networks; however, you have never seen optical modules. actually. Optical modules should be used in optical communication, data centers and other places. So, there are few places where we use optical modules in our daily life, so what is the role of optical module spoilers?

　　The optical module is composed of optoelectronic devices, functional circuits and optical interfaces. The optoelectronic devices include two parts: transmitting and receiving.

　　Simply put, the function of the optical module is photoelectric conversion. The transmitting end converts the electrical signal into an optical signal, and after transmission through the optical fiber, the receiving end converts the optical signal into an electrical signal.

　　And, according to the packaging classification, optical modules can be divided into:

　　1. The XFP optical module is a hot-swappable, communication protocol-independent optical transceiver for 10G bps Ethernet, SONET/SDH, and Fibre Channel.

　　2. SFP optical module, small pluggable transceiver module (SFP), is currently widely used.

　　3.GigacBiDi series single-fiber bidirectional optical modules use WDM technology to realize bidirectional signal transmission over a single fiber (point-to-point transmission. Especially when fiber resources are insufficient, one fiber is required to transmit bidirectional signals). GigacBiDi includes SFP single fiber bidirectional (BiDi), GBIC single fiber bidirectional (BiDi), SFP+ single fiber bidirectional (BiDi), XFP single fiber bidirectional (BiDi), SFF single fiber bidirectional (BiDi) and so on.

　　.Electrical port module, RJ45 electrical port small pluggable module, also known as electrical module or electrical port module.

　　5. SFF optical module, according to its pins is divided into 2x5, 2x10, etc.

　　6. GBIC optical module, Gigabit Ethernet interface converter (GBIC) module

　　7.PON optical module, passive optical network PON (A-PON, G-PON, GE-PON) optical module

　　8.40Gbs high-speed optical module.

　　9.SDH transmission module (OC3, OC12)

　　10. Storage modules, such as 4G, 8G, etc.
