Abstract: There is proposed a mechanism for monitoring optical fibers (1) in an optical backhaul network that connects nodes (10, 20) of a distributed radio base station system. The nodes carry data streams using the Common Public Radio Interface (CPRI) protocol. The method includes: receiving from at least one node a CPRI alarm indicative of a transmission failure in a CPRI data stream, and triggering fault analysis of an optical fiber identified as carrying the CPRI data stream. Using CPRI alarms that are generated by transmission failures between nodes as a trigger for monitoring the physical fiber carrying the CPRI streams provides a targeted mechanism for determining fiber failures, which had a low response time and thus enables rapid repair of any fault and minimal disruption to the network.
