The Japan-U.S. Cable Network completed a 200G trial over a segment of its network on the U.S. West Coast. The trial employed Ciena’s submarine solution and 16QAM (quadrature amplitude modulation) using the company’s 6500 Packet Optical platform and WaveLogic coherent optical technology. The trial was successfully conducted earlier this year on a 630 km submarine segment in California, and builds on the successful deployment in 2013 of Ciena’s 100G submarine solutions across the Japan-U.S. Cable Network.
Ciena said the trial demonstrates how 16QAM technology can be leveraged to double the number of bits per wavelength to support twice the amount of data compared to standard 100G technology.
“The Japan-U.S. Cable Network is a critical source of capacity for our consortium members. The goal of this trial was to ensure that the cable’s various segments can be equipped with appropriate future-proof technologies to scale network capacity in a cost-effective manner, as needed to meet rapidly increasing demand for bandwidth. This collaboration with Ciena is helping the network prepare for cost-effective growth.”
