The optical module, known as Optical Transceiver in English, is a general term for various module categories, including optical receiver modules, optical transmitter modules, optical transceiver modules, and optical forwarding modules. As an essential component of optical fiber communication, optical modules are optoelectronic devices that facilitate the conversion between optical and electrical signals during the transmission process. An optical module usually consists of an optical transmitting device (TOSA, including a laser), an optical receiving device (ROSA, including a photodetector). Everything you need to build an optical network from end-to-end. Thin-film filter and PLC based AWG for multiplexing, a full suite of components for optical amplification use, optomechanical or MEMS-based switches for protection or surveillance application, Tap PD for power monitoring and VOA for. That is, metal medium communication represented by coaxial cables and network cables is gradually being replaced by optical fiber media.
