ROSA Optical Component 1.25Gbps

ZKTel's 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 two 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 second types are known as Coaxial Modules which consists of Fiber Pigtails.
