TOS1000E Optical Switch Module HFC Headend Optical Devices For Digital TV Signals
Overview
TOS1000E optical switch module can be used as an automatic switch in optical network and optical transmitter backup. When the main optical path signal fails or RF signal is interrupted,it can automatically switch to the standby one to maintain the optical signal transmission.This product is equip with the imported high-performance switching devices , With RF signal monitoring function at the same time, ensuring the normal network signal transmission. The built-in automatic monitoring system ensures superior performance.
