Operation and Maintenance
Provide the Web based OMT software via Ethernet connection for the commissioning of DAS system. The MU and RU are communicated over the optical Fiber, hence, the RUs can be remotely controlled by connection
to MU locally or remotely Adjustable parameters include: On/off Switch, Uplink Gain Setting, Downlink Gain Setting, Output Power Adjust,
Alarm Threshold Setting, etc. Monitored parameters include: Downlink Output Power, Temperature, Optical Power, etc. Alarm parameters include: Power Supply, Optical Alarm, Door Open, Temperature, Software, Hardware, shutdown
etc. An optional Operations and Maintenance Center (OMC) software to monitor a large volume of DAS system remotely.
