Abstract
To address the difficulty of effectively increasing the input power for fiber optic hydrophone repeaterless transmission,fiber nonlinearity hindering the power enhancement is analyzed,and a solution is proposed by using negative dispersion fiber to suppress the modulation instability,which is the main obstacle for the system.By combining low-loss fiber and distributed Raman amplification,the transmission link loss performance is further optimized,and the noise reduction effect is verified in the repeaterless transmission experi-ment.The offshore distance of the fiber optic hydrophone array reaches 130 kilometers,and the transmission noise is-97 dB,providing good technical support for building high-reliable underwater sensing applications.关键词
