Field trial of all-optical 40 Gbps transmission system for next-generation networks

Abstract

The National Institute of Informatics (NII) has been conducting joint research with Japan-Telecom to develop a 40 Gbps optical transport system for the next-generation SuperSINET. We report on the recent results of field trials focused on automatic chromatic dispersion compensation and path protection/restoration applied to the future SuperSINET as key technologies required to maintain the quality of transmission, to reduce operational costs, and to facilitate the enhancement of network capabilities. From the results of the field trial, we have confirmed that an automatic optical path control system is essential in an all-optical wavelength path network.

Development and evaluation study on GMPLS peer model to realize optical quality control

“…The feasibility investigations are to realize the effective use of unified control plane for optical quality control of label path and to enable use of control equipments (dynamic CD compensator) to detect quality conditions inside of unified control plane. We evaluate the real-time compensation performance for optical quality control of label path and report of the results of the field trial has been made [5].…”

Recent Research Activities on GMPLS-based Full-Optical Networks

“…In [10], we reported the results of field trial focused on automatic CD compensation and path protection/ restoration of full-optical 40 Gbit/s transmission system. The network protection function was provided by a PXC using GMPLS signaling.…”
