Optical Sub Assembly

Optical Modules are electronic components that convert an electrical signal to an optical signal simultaneously. Optical Modules are categorized into LD (Laser Diode) Modules and PD (Photo Diode) Modules. Optical Transceivers are packaged PD and LD Modules. These products are the core devices for any optical communication system such as an Optical Transponder and an ONU (Optical Network Unit).


Optical Modules are divided into two industry types. One type is known as Receptacle Modules. This type is represented by a TOSA (Transmitter Optical Sub-Assembly) and ROSA (Receiver Optical Sub-Assembly) Assemblies. The second types are known as Coaxial Modules which consists of Fiber Pigtails.
