Modulation instability (MI) is the main limitation factor of the maximum optical power in long-haul phase-sensitive optical time domain reflectometry (Φ-OTDR), and induces signal fading and serious phase noise. In this paper, a method of coherent seed injection is proposed to suppress the MI-induced phase noise in long-haul Φ-OTDR. The spontaneous MI is suppressed by stimulating induced MI in an optical fiber. The visibility of the signal in Φ-OTDR is enhanced and the phase noise is suppressed significantly. This paper offers an effective method to increase the maximum input power with the MI-induced phase noise suppressed in the long-haul Φ-OTDR system. As a result, the maximum input power and sensing distance can be potentially increased, which is greatly beneficial to the enhancement of the performance of long-haul Φ-OTDR.

“…To reduce the destruction and avoid accident, Integrity monitoring of oil and gas pipelines requires that a safety surveillance system be able to quickly identify oil stolen by drilling hole or third party intrusion event, and those behavior will lead to great property loss and even environmental pollution problems. Distributed optical fiber sensing technology provides an incomparable pipeline safety management system that is more and more popular in the whole world [1,2].…”
