NEC successfully achieves world-leading 800 Gbps long-distance transmission with submarine optical cable

NEC has successfully conducted a long-distance field trial of an undersea optical cable system using a new transmitter with the world's highest level of 800 Gbps transmission performance.

Field test implementation route

The field test was conducted using the Indonesia Global Gateway (IGG) submarine optical cable of PT Telekomunikasi Indonesia, tbk (hereinafter referred to as PT Telkom), the largest telecommunications operator in Indonesia, and NEC's latest transmission device XF3200. Through the field test, NEC implemented 800 Gbps optical wavelength division multiplexing transmission and successfully achieved the world's longest long-distance transmission of more than 2,100 kilometers.

During the trial, the XF3200 transmitter was used to increase transmission capacity by approximately 30% compared to the NEC products currently in use, making it an ideal device for meeting the expanding needs of international communications. In addition, the adoption of new designs and technologies can save space, reduce energy consumption, and provide high scalability and flexible maintenance, helping to reduce total cost of ownership.

"We would like to thank PT Telkom for their full support in achieving this world-first result," said Yoshihisa Inada, General Manager of NEC's Marine Development Division. "This achievement demonstrates NEC's leadership in ultra-high-speed optical transmission systems. We will continue to challenge ourselves to achieve greater capacity, greater flexibility, and greater cost-effectiveness in submarine communications."

Toto Sugiharto, Senior General Manager of PT Telkom, said: “NEC has been a key partner in our submarine cable systems for many years. This field trial demonstrates that NEC’s high-quality submarine optical transmission technology has been further developed to meet Indonesia’s growing communications needs.”

As the world's leading supplier of submarine optical cable systems, NEC has laid more than 400,000 kilometers of cables over the past 50 years, enough to circle the earth 10 times. As a reliable system integrator, NEC provides all services including manufacturing of submarine optical cables, submarine repeaters, and land transmission equipment, ocean surveys and route design, installation and laying construction, training, and delivery testing. The submarine optical cables are provided by OCC Co., Ltd., a subsidiary of NEC, and the submarine repeaters are manufactured by NEC Platform Co., Ltd.
