Simulation of Information Transmission System for Seafloor Observation Platform

Abstract

This paper presents a scheme of information transmission system for undersea observation platform based on all-optical network. Through flexible using of WDM, OADM, EDFA, RFA, DCF and other technology, it effectively compensates chromatic dispersion, restrains nonlinear effects and noise problems. Fibers in primary nodes are directly assigned to ensure mutual independence between different transmission links. Dual-fiber bidirectional transmission mode that wavelength of one fiber drops to the node by OADM, then return to the same transmission station in the other fiber, increases the reliability of the transmission system. The simulation results show that this scheme can ensure information transmission quality and effectively achieve wavelength adding and dropping, further verify the feasibility of the scheme.
