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). We manufacture and provide the components that are used in Optical Modules and Assemblies. We have the ability to design and provide products from a trial sample basis up to a mass production level. Optical Modules are divided into several industry types. One type are known as Receptacle Modules. This type is represented by a TOSA (Transmitter Optical Sub-Assembly) and ROSA (Receiver Optical Sub-Assembly) Assemblies. The other types are known as Coaxial Modules which consists of Fiber Pigtails, and Butterfly Modules. We manufacture and provide Fiber Stubs, Receptacle Assembly and Transceiver Housings for Receptacle Module Components. In addition, we manufacture and provide Metal Ferrule Assemblies, Pigtail Fiber Assemblies, Lensed Fiber Assemblies, Metallized Fibers, Lens Assemblies, Optical Isolator and others for Coaxial Modules and Butterfly Modules as well.
