Reliance Globalcom 
completed an upgrade of its FNAL submarine network using Ciena’s coherent 40G optical networking solution. The enhanced network brings massive capacity increases to two key routes that each span approximately 5,000 kilometers to connect Japan, Taiwan, South Korea and Hong Kong. The first project is described as the first coherent 40G submarine network in Asia, adding approximately 4 terabits of aggregate capacity. THE upgrade is also believed to be the first submarine deployment with reconfigurable optical add-drop multiplexers (ROADM), which provide flexibility to add or drop select wavelengths at intermediate sites
Ciena provided its 6500 Packet-Optical Platform with 40G ultra long haul interfaces, which are designed to significantly increase submarine network capacity without disrupting existing customer traffic or adding cost and complexity to the network. Ciena also provided Deployment Services and quickly turned up the system with in-service traffic migration from existing 10G to coherent 40G.
