Equipment Configuration And Optical Amplifier Module Analysis For Long-span Unrepeatered Optical-fiber Communication Systems

It is of great significance for the security operation of ultra-high voltage power grid to construct long-span unrepeatered optical-fiber communication systems combined with ultra-high voltage power grid.After summarizing the inside and outside research status and the key technology of the unrepeatered optical communication system,the following items are researched:Based on the simple principle of the power budget,the required equipment schemes for different spans of unrepeatered transmission systems operating at different bit-rate are given;Based on the semi-analytical modeling of fiber Raman-amplification(FRA), the relationship between the configuration parameters and performance parameters of FRA is simulated and analyzed;Based on the numerical computation modeling of the Erbium-doped fiber amplifier(EDFA),the relationship between the configuration parameter and performance parameter of the Remote pump amplifier(ROPA) is simulated and analyzed.The results of the equipment schemes for different unrepeatered systems provide reference for the practical deployments of the long-span unrepeatered electric power optical-fiber transmission systems. The simulation and analysis results of the FRA and ROPA modules provide theory for the performance optimization of the long-span unrepeatered electric power optical-fiber transmission systems.
