NEC Corporation has completed a long-distance field trial of an optical submarine cable system using a new transponder with the highest level of transmission performance in the world, 800 gigabits per second (Gbps), according to NEC research.

This record-breaking field trial was conducted using the Indonesia Global Gateway (IGG) optical submarine cable owned by PT Telkom Indonesia (Persero) Tbk (Telkom), Indonesia's largest telecommunications carrier, and using NEC's latest transponder, the XF3200. NEC conducted the longest wavelength division optical transmission of 800 Gbps optical signals over 2,100 km in the field trial.

The XF3200 transponder supported approximately 30% more transmission capacity than NEC products currently in use during the trial, making it the ideal device to meet ever-increasing international communications demand. A new design and the use of cutting-edge technologies also allow for space savings, low power consumption, high scalability and flexible serviceability, all of which contribute to a lower total cost of ownership.

"We thank Telkom Indonesia for their full support in obtaining this kind of result for the first time in the world," Senior Director, Submarine Network Division at NEC Corporation, Yoshihisa Inada, said. "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."

Executive General Manager, Infrastructure Planning Division at Telkom, Toto Sugiharto, said, "NEC has been an important partner for us 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."

For more than 50 years, NEC has been a leading global vendor in the submarine cable system business, constructing over 400,000 km of cable that spans the globe nearly ten times. NEC is well-known in the submarine cable industry as a dependable partner that provides all aspects of submarine cable operations, such as the manufacture and installation of optical submarine cables and repeaters, ocean surveys and route designs, training and delivery testing. NEC subsidiary OCC Corporation manufactures submarine cables, and NEC Platforms, Ltd. manufactures submarine repeaters.
