Shenzhen Qianwanzai Communication Technology Co., Ltd.

Bezirk/Stadtteil: 51 F Hopewell Centre 183 Queens Road East Hongkong

It includes optical fiber connectors, optical fiber couplers, wavelength division multiplexers, optical attenuators and optical isolator, etc., which are the joints of optical transmission systems.
Optical connectors are the widely used and the numerous devices in optical passive devices, followed by couplers and wavelength division multiplexers, and other devices are used less. With the development of optical communication technologies, the demand for dense optical wavelength division multiplexers and large port number matrix optical switches will gradually
Optical passive devices are an important part of optical fiber communications equipment and are indispensable components for other optical fiber applications. With high return loss, low insertion loss, high reliability, stability, mechanical wear resistance and corrosion resistance, easy to operate, etc., which are widely used in long-distance communication, regional networks and fiber to the home, video transmission, optical fiber sense test and so on.
