In-service, OTDR-based monitoring
Monitoring of PON networks is available today via OLT and ONT interaction. While this monitoring provides visibility into the operation of the network, it is based on the electronics in the OLT and ONT being operational. When there is a fiber problem such as a cut, traditional PON monitoring tools are unable to troubleshoot physical fiber plant issues and identify the true root cause and location of the fault. This limitation stems from their reliance on the network being active and operational. With our ALM in-service OTDR-based fiber monitoring solution, this issue is eliminated.
Adtran ALM advanced fiber monitoring solution
A critical component of troubleshooting any network interruption is quick and accurate root cause analysis. The use of in-service fiber monitoring provided by our ALM complements traditional PON management methods by providing direct physical fiber plant information about fiber health, including attenuation as well as fiber cuts. This capability enables network operators to take immediate, targeted action, while also preventing false alarms and unnecessary truck rolls. This shortens the repair cycle, improves the availability of a fiber link and also speeds up installation and commissioning of fiber services.
Benefits beyond live network monitoring
Traditionally, fiber monitoring has been viewed primarily as a tool for “post-network installation,” assisting in troubleshooting and restoring network service. Its primary purpose was to maintain the functionality of an existing, active network. However, the advantages of fiber monitoring extend well beyond addressing common live network issues.
Monitoring and certifying PON physical fiber plant is a challenge for network providers. Given the vast scope and rapid pace of service deployment for potentially thousands of residential subscribers, ensuring proper installation and certification of the fiber is crucial. Many companies use third-party contractors for their installation. However, inconsistencies in installation quality and incomplete documentation frequently arise, leading to issues when turning up services. ALM fiber monitoring is a valuable tool to aid in the construction of PON fiber plants to validate and document the fiber plant from a central location. In addition to monitoring and validating the passive fiber plant including feed-fibers and splitters, our ALM can also aid in the installation of the OLT and ONTs. With our innovative Deep PON assurance technology, our ALM provides visibility down to individual businesses and residences to ensure they are installed properly and seen by the network at turn up, aiding the OLT and associating the ONT with the proper fiber connection and OLT connectivity. Moreover, users can easily identify fiber versus electronics as the root cause of events.
