DWDM 100G ring for backbone Network using dark Fiber

This paper focuses on designing and analyzing a 100G DWDM backbone communication network under dark fiber for the ring topology. It aims to explore how organizations can leverage available dark fiber assets to deliver a multiprotocol label-switching-enabled optical transport network as bandwidth requirements for data transmission increase. The performance evaluation approach demonstrated is based on network design, simulation, and case study analysis. Measures like the ones discussed earlier, including throughput, latency, and fault tolerance, are discussed. The outcomes yield that a 100G DWDM ring greatly upgrades the bandwidth capability with low latency and network dependability. Dark fiber is economical, flexible, and can be added to future system requirements. It is also compared with other network architectures and designs to illustrate the benefits of the proposed system in terms of its performance and costs. The paper makes recommendations on the application of  DWDM 100G networks in metros and regional backhaul, and directions for future studies are provided in the conclusion.
