NEC Achieves Longest 800 Gbps Optical Transmission

Japan-based NEC Corporation in a press release on September 28 has announced the successful completion of a long-distance field trial on an optical submarine cable system owned by PT Telkom. According to the NEC, the new submarine cable system uses a new transponder that has the world's highest level of transmission performance of 800 Gbps.

The trial was conducted using the Indonesia Global Gateway (IGG) optical submarine cable owned by PT Telkom Indonesia , (Telkom), which is Indonesia's largest telecommunications carrier.The trial used NEC's latest transponder, the XF3200. NEC used WDM technology to transmit optical signals of 800 Gbps over 2,100 kilometers, which is the longest distance ever recorded.

During the trial, the XF3200 transponder supported approximately 30% higher transmission capacity than NEC products currently in use, making it the ideal device to meet ever-expanding international communications demand. Also, a new design and the adoption of the latest technologies enable space saving, low power consumption, high scalability, and flexible serviceability, which contribute to lower total cost of ownership.

Yoshihisa Inada, Senior Director, Submarine Network Division, NEC Corporation said that NEC thank Telkom Indonesia for their full support in obtaining the kind of result for the first time in the world. He also added that this achievement is a confirmation of NEC's leadership in ultra-high optical transmission systems and we will continue to explore the limits of even greater subsea capacity, flexibility and cost-effectiveness.

Toto Sugiharto, Executive General Manager, Infrastructure Planning Division, Telkom, commented that NEC has been an important partner for PT Telkom in submarine cable systems for many years. This field trial proves that NEC's high-quality submarine optical transmission technology has further evolved, thereby helping to meet the increasing traffic demands throughout Indonesia.

NEC is a leading global vendor in the submarine cable system business for more than 50 years. NEC has built more than 400,000 km of cable. NEC is well-established as a reliable partner in the submarine cable field as a system integrator that provides all aspects of submarine cable operations, including the manufacture and installation of optical submarine cables and repeaters, provision of ocean surveys and route designs, training and delivery testing. Submarine cables are manufactured by NEC subsidiary OCC Corporation, and submarine repeaters are manufactured by NEC Platforms, Ltd.

800 Gbps has been announed earlier too. This might be the first time to achieve such a long distance. Interesting!
