The optical switch unit launched by Sino-Telecom is used for monitoring multiple channels of optical signals, automatic switching between LAN multiple light source and the detector, as well as optical sensing of multi-point dynamic monitoring system. Real-time monitoring of multiple optical channels by only one unit of device can be realized, so as to save the investment on devices.

Two working modes--manual routing and custom duration routing are provided for option. The insertion loss is less than 1.1dB, and the switching time between adjacent channels is less than 10ms. A variety of management modes such heartbeat protocol management and local console are supported. Moreover, LED display and buttons are designed, which enable users to manually check the device status with easy operation and without any extra tool.
