PON OTDR is designed for testing modern FTTx and passive optical networks, helping technicians locate fiber faults, measure optical loss, and verify network performance in PON environments.

With the increasing deployment of GPON, EPON and XG(S)-PON networks, traditional OTDR testing methods may not meet the requirements of live fiber environments. PON OTDR supports advanced testing functions for access networks, including live fiber testing, PON network troubleshooting and accurate fault location.

3S Telecom provides PON OTDR solutions for telecom operators, installers and maintenance teams, helping improve installation efficiency and reduce network downtime.
