NEC Trials 800G over 2100km on IGG Cable System

NEC Corporation has successfully completed a long-distance field trial of 800 Gpbs on Telin's Indonesia Global Gateway (IGG) submarine cable system, achieving wavelength division optical transmission of 800 Gbps optical signals over 2,100 km, the longest ever recorded.

The Indonesia Global Gateway (IGG) is a private subsea cable owned by PT Telkom Indonesia (Persero) Tbk (Telkom Indonesia) and its international subsidiary Telin, spanning 5,300 kilometers to connect the cities of Dumai, Batam, Jakarta, Madura, Bali, Makassar, Bilikpapan, Takaran and Manado with Tuas, Singapore. The IGG cable system consists of 4 fiber pairs, initially designed with 100Gbps x 80 wavelengths DWDM technology, ready for service in May 2018.

This record-breaking field trial was conducted using NEC's latest transponder, the XF3200. In the field trial, NEC conducted wavelength division optical transmission of 800 Gbps optical signals over 2,100 km, the longest 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.

Earlier in 2022, Nokia collaborated with Telin to trial 500Gbps per channel on the IGG cable system, over a distance of 3,551 km between Telin's data center in Jurong, Singapore to Manado in Indonesia. The trial recorded a fiber capacity of 11Tbps in the 2.2THz of optical fiber spectrum, equivalently 22Tbps per fiber pair.
