Optical passive components don't need extra energy drive work of optoelectronic devices.


Including optical fiber connector, fiber coupler, WDM, optical attenuator and optical isolator, optical transmission system is of the joints.

Optical connector is the most widely used in optical passive components, the largest number of devices, coupler and wavelength division multiplexer times, few other device. With the development of optical communication technology, the dense wavelength division multiplex, big port number matrix optical switch demand will gradually increase.
