Abstract

A flexible semi-filterless architecture for metro DWDM networks with ring- or horseshoe topologies is presented. ROADM nodes are based on wavelength blockers. Coherent transmission enables filterless channel selection. Critical parameters are determined and a 4-span, 160-km horseshoe with 100Gbit/s DP-QPSK and 200Gbit/s DP-16QAM is demonstrated.

基于波长阻挡和相干传输的灵活城域网架构

提出了一种适用于环形或马蹄形拓扑的城域DWDM网络的柔性半无滤波器结构。ROADM节点基于波长阻断器。相干传输使无滤波器信道选择成为可能。确定了关键参数，并演示了具有100Gbit/s DP-QPSK和200Gbit/s DP-16QAM的4跨160 km马蹄铁。
