Optical Line Monitoring丨C-LIGHT

Optical Line Monitoring

C-LIGHT Optical Line Monitoring (OLM) is a critical monitoring technology for fiber-optic communication networks. It evaluates the health status of optical fiber lines by analyzing real-time optical signal parameters such as optical power, loss, and reflections. Typically utilizing tools like Optical Time Domain Reflectometers (OTDR), OLM accurately locates issues such as fiber breaks, bends, or connector failures, while providing early warnings and diagnostic functions. This enhances network reliability, reduces fault recovery time, and lowers maintenance costs. Widely applied in telecommunications, data centers, and industrial communications, OLM is an essential component of intelligent optical network management.

Product Details

CL-OTN-3900 optical cable monitoring system combines optical cable monitoring, alarm, fault analysis, positioning, fault management, line maintenance and line management to ensure the safe and efficient operation of the optical cable network. It can automatically monitor the communication optical cable 24 hours a day and automatically switch and protect the optical fiber. It can timely and accurately report the sudden optical cable fault, effectively shorten the fault duration, and It is necessary to find the potential faults that are hidden and not yet detected, but will cause communication interruption, and give accurate early warning, so as to achieve active maintenance and take preventive measures.
