It performs the electro-optical conversion and includes components such as the laser, MPD, TEC, isolator, Mux, and coupling lens. It comes in various packaging forms like TO-CAN, Gold-BOX, COC (chip on chip), and COB (chip on board). As an important part of the optical fiber communication system, the optical module plays the role of photoelectric conversion. CDR not only ensures signal integrity and stability but also plays a pivotal role in. Optical modules are devices used to connect network devices, transmit and receive data between network devices, and can be used to convert optical and electrical signals.
