Build long - span optical fiber communication system without repeaters is of great significance for the use of UHV power grid transmission power system information . This article describes the relay optical fiber communication technology and its research status of the power system , both dispersion compensation fiber and chirped fiber grating dispersion compensation technology , and research and analysis to determine chirped fiber Bragg grating dispersion system solutions compensation ; repeater optical transmission system introduced by stimulated Brillouin scattering threshold changes in fiber Raman amplifiers provide a reference for the optimal allocation ; Finally, 2.5Gbit / s single- channel 380km long span relay optical fiber communication system program for the future practical application configuration .
