Resilience is the ability to provide and maintain an acceptable level of service in the face of faults and challenges to normal operation. In order to increase the resilience of a given communication network, the probable challenges and risks have to be identified and appropriate resilience metrics have to be defined for the service to be protected.
Most of the times, the GPON networks are only tested under “normal operation”, so once deployed, there are many events that cannot be identified as they have never seen before. Testing the behavior of the network under error conditions will tremendously benefit the operator to be prepared when these situations happen in real life.
GPONDoctor Whitepaper “The Road to the Deep Understanding of your FTTH Network-Proactive versus Reactive Network Management” explains the benefit to use an Error injection test gear to improve the resiliency of your FTTH GPON network.
