    Internal Structure of the Optical Module

    The optical module is usually composed of Transmitter Optical Subassembly (TOSA, containing a laser LD Chip), Receiver Optical Subassembly (ROSA, containing a photodetector PD Chip), a driving circuit, and an optical and electrical interface. Its schematic is shown in Figure 1. The internal structure of an optical module is complex but can be divided into several main parts. The transmitting interface inputs electrical signals of a certain bit rate, which are then processed by internal driver chips. TOSA and ROSA in Common Optical Transceiver Modules For ordinary optical transceiver modules, there are two optical devices, TOSA and ROSA, which have opposite effects. It is the core device for connecting communication equipment with optical fibers.
