Question 2 (C4, CO,PO2) (a) Consider that the Logistic / Freight company plan to deploy Wide Area Netwodk (WAN) core optical network infrastructure and Clood Services (Data Centres) in which organization operation are throughout the branches. Table I shown the Nodes and Data Centres for company with data rates of 2006 bps is being setup for each links networks. Suppose Servers at Data Centre are connected to Disaster Recovery Data Centre (DRC) via optical networks for restoration and backup purposes. Assume a 10 dB power margin for losses in connectors. (i) Construct and illustrate the optical networks infrsstructure connectivity in Mesh topology by providing the nodes with Core Rociter, Optical Cross-conncet / WDM as in Table 1. (i) Evaluate the maximum length of the optical link from ingress to egress, assuming that there ars no amplificrs. (tii)If the link operates at a rate of 415 Gbps and an average dispersion limit of 1100 Gboskm. Rate the maximum length of the optical links from ingress to egress. 2 TARTE
