Recently, Japan’s NEC announced that it has successfully completed a long-distance field test of its subsea cable system using a new transmission device with the world’s highest transmission performance of 800 Gbps. The test used the largest telecommunications operator in Indonesia, PT Telekomunikasi Indonesia, for the subsea cable system. The latest transmission device, XF3200, was also used in the test. Through the trial, NEC implemented 800 Gbps light wavelength division multiplexing transmission, achieving the longest transmission distance of over 2,100 km in the world.
Officials said that during the trial, the transmission capacity of the XF3200 transmission device was improved by about 30%, making it an ideal device for meeting the growing demand for international communication. In addition, the adoption of new designs and technologies can save space, reduce energy consumption, and provide high scalability and flexibility in maintenance, helping to reduce the overall ownership cost.
This successful test flight will provide faster and more stable transmission for subsea cable systems, supporting the development of global communication. At the same time, it demonstrates NEC’s research and manufacturing capabilities in optical communication technology, laying the foundation for future communication technology.
