The OpTxA-Mk2 is a stand-alone measurement and monitoring device for active optical fibers. It contains an integrated optical coupler and a power meter. The thresholds for the optical power values are easily programmable with the built-in keys. The integrated display shows the measurement values and settings.

The sensor is equipped with dry output relay contacts to allow for remote alarming. Additionally it can be supplied with plug-in interface modules for the LANCIER Tx-Bus or CAN-Bus in order to integrate it into the Unified Monitoring System (UMS). Especially when combined with an OTDR-based monitoring system (refer to RTU) an all-inclusive surveillance of dark and active fibers can be realised very economically.
