High Degree ROADM Cluster Node

Abstract

A low-cost ROADM cluster node with flexible add/drop and scalable to 100s of degree is proposed for next generation optical networks. It disaggregate line and add/drop functions of the cluster into different chassis. A proposed order-based connection management algorithm achieves better than 10−4 blocking despite less than 30% dilation in cluster design. © 2021 The Author(s)
