摘要：

In this paper, a long-range phase-sensitive optical time-domain reflectometer (f-OTDR) system is proposed, which is based on the direct detection type f-OTDR system, combined with the first-order forward Raman distributed amplification technology and remote pump amplification technology, to achieve 130km vibration monitoring range and 20m spatial resolution. Compared with relay EDFA amplification technology and bidirectional distributed amplification technology, the system eliminates the necessity of a remote power supply, which is of great significance in the monitoring application of long-distance OPGW optical cable.
