ONMSi (Optical Network Management System) is a system for remote management and monitoring of optical cable network. ONMSi allows you to check integrity of optical cables and detect and locate faults on them. It provides comprehensive monitoring that includes detection of attenuation, reflectance, fiber breakage and fiber elongation and further provides a clear graphical overview of monitored fiber performance.
ONMSi system can be composed of a large number of components, where different combinations provide a wide range of possibilities. ONMSi system primarily consists of a server with a reliable database and software for monitoring, alarming, reporting and geographic location and strategically deployed OTU (Optical Test Unit) units containing OTDR and optical switch.
ONMSi system works in such a way that OTUs perform cyclic OTDR trace measurements and send alarms to server via Ethernet / IP connection if the measured result on the trace deviates from the reference trace by an amount greater than a predefined thresholds. In case of interruption of communication between OTU and ONMSi server, OTU alarm is sent directly to the system administrator via e-mail or SMS.
