Abstract

Abstract: With the construction of ultra-high voltage (UHV) transmission network, the ultra-long distance optical fiber communication technology has found increasing applications, and the 10 Gb/s ultra-long distance optical fiber communication has been applied in many UHV projects. According to the main factors that influence the 10 Gb/s transmission system and the application of available technologies in domestic and overseas ultra-long distance optical fiber communication, the paper proposes a construction scheme of experimental circuit for ultra-long distance optical fiber communication based on a multi-terminal HVDC project of China Southern Power Grid. The transmission distance reaches 470 km in the experimental circuit by using ultra-long span optical transmission technology combined with second-order Raman amplify and first-order ROPA. The equipment configuration and software calculation conclusions are presented in the paper. The experiment results will provide valuable experiences for similar projects in the future.

Key words: ultra-long span optical transmission system, ultra-high voltage, ROPA, Raman amplify, ultra-low loss optical fiber
