Value of Reach Extension in Long-Distance Networks

摘要

A long-distance traffic model for the USA network is used to analyze the fraction of traffic that could pass through the nodes transparently, eliminating the need for redundant regeneration in the pass-through channels. An economic analysis quantitatively demonstrates the value of extending the transparent reach length from 600 km to 2500 km in the USA long-distance network, achieving a cost-effective configurable network using optical switching technologies that route optical channels and bypass regeneration sites optically wherever possible.
