Optical sub-assembly is basic product for the fiber optic communications industry.
We can provide optical TOSA module and optical ROSA module, regarding the package different it has pigtail and receptacle.
Optical sub-assembly is a necessary component of fiber optics products, transmitter (TOSA) and receiver (ROSA) optical sub-assembly are included.
TOSA consists of a laser diode, optical interface, monitor photodiode, metal and/or plastic housing, and electrical interface. Depending upon the required functionality and application, other components may be present as well including filter elements and isolators. It is used to convert a signal into an optical signal coupled into an optical fiber cable.
ROSA consists of a photodiode, optical interface, metal and/or plastic housing, and electrical interface. Depending upon the required functionality and application, other components may be present as well including amplifiers. It is used to receive an optical signal from a fiber and convert it back into an electrical signal.
We have our own factory so that we can provide high-performance and high-quality optical sub-assembly. Our product is already approved by the U.S.A, Europe, Canada, Korea and Japan…etc.
