The optical module is one of the core accessories of network communication, the role of photoelectric conversion, the transmitter side of the electrical signal into optical signals, through the optical fiber transmission, the receiver side and then convert the optical signal into electrical signals. Simply put, where optical fibers are used, optical modules are used. So what are the application equipment and scope of optical modules?

1, Switch: in the enterprise network deployment, data centre construction are inseparable from the optical module and switch, optical module is mainly used for the transmission of electrical signals and optical signals, while the switch is the optical and electrical signals to play a forwarding role, the switch will use GBIC, 1 * 9, SFP, SFP +, XFP optical modules, etc..

2, Server: the server is generally used with the switch, with the switch using optical modules corresponding to

3, Fiber optic transceiver: fiber optic transceiver is mainly used in the long-distance network due to the network cable can not cover, need to use fiber to extend the signal transmission, commonly used in fiber to the home, security monitoring, community network construction and radio and television transmission and other fields. Fiber optic transceiver using 1 * 9 and SFP optical modules

4, Fiber optic router: fiber optic router network port is the use of optical fiber, can be used to resolve the optical signal in the incoming fiber. Fiber optic routers generally use SFP optical modules

5, Fiber optic network card: fiber optic network card can provide a reliable fiber optic connection for the user‘s computer on the Fast Ethernet network, providing users with a reliable fiber to the home and fiber to the desktop solution. Fiber optic NICs use 1*9 optical modules, SFP optical modules, SFP+ optical modules, etc.

6, Video optical transceiver: whether analog optical transceiver or digital optical transceiver, optical modules are needed. The optical module integrates the drive circuit and laser, photodetector and amplifier together modularly, making the digital optical transceiver a debugging-free product, which greatly improves the stability of field applications. Generally use 1 * 9 single-mode optical module, some high-definition class optical transceiver will also use SFP optical module, such as fiber optic high-speed dome machine.

7, Base station: in the mobile communication system, mobile communication base stations need optical modules to achieve interconnection between equipment, connecting the fixed part and the wireless part, and through the air wireless transmission and mobile stations connected to the equipment .  Communication base stations often use SFP, XFP optical module.
