摘要：

The rapid increase in traffic flowing through data centers and mobile networks in recent years is making it increasingly important that the supporting optical trunk line networks have highspeed, high-capacity, long-distance, and high-reliability features. Various types of applications have been discussed for flexibly reconfiguring the optical trunk line networks, and it is agreed that flexibility and high availability are needed at the optical level. In its development of a re configurable optical add/drop multiplexer (ROADM) that serves as an optical-direction switch, Fujitsu focused on the implementation of "colorless, directionless, contentionless, and gridless (CDCG)" functions to meet the needs of telecom carriers for greater flexibility, remote operation, and higher capacity. This paper introduces the key devices and elemental technologies of CDCG-ROADMs, describes CDCG-ROADM functions, and touches upon the application of CDCG-ROADM technology to future optical trunk line networks.
