OBP 2X2B optical bypass protection module
Description:
OBP-2X2B optical bypass protection module is an automatic switch for optical path failures. The module is generally used to connect multiple optical transceiver devices in series in an optical fiber optical path. Each transceiver is at a different base station. When a base station of an optical transceiver is powered off or there is no optical signal at the transmitting end of the transceiver, the optical bypass protection module will automatically identify that the base station is faulty. At this time, the optical path automatically switches to bypass the base station at the fault point, thereby achieving normal operation of other base stations.
Features:
- Low insertion loss and high reliability
- Real-time monitoring of the optical signal at the transmitter
- Automatic switching of power and light failure signals
- LED indicator light status display
