Infinera says Unity Submarine Cable System, which spans across the Pacific is using the vendor’s ICE6 800G coherent optical solution modernise and increase capacity on the 9,620 kilometre transpacific route linking Japan and the U.S. Infinera’s ICE6 solution will double the capacity of the cable system.

The Unity Submarine Cable System is a subsea consortium representing Bharti Airtel Limited, Global Transit Limited (a wholly-owned subsidiary of TIME), Google, KDDI Corp., Telstra and Singtel. Infinera says that by upgrading the network to ICE6, the consortium will be able to increase the life span of the cable by nearly 25% and deliver up to 7.4 Tbps per fibre pair. This modernisation with Infinera’s ICE6-powered GX Series solution also enables operators to get the most out of the subsea cable by minimising cost per bit while maximising the spectral efficiency and fibre capacity. This level of performance is achieved by leveraging Infinera’s solution features that include Nyquist subcarriers, forward error correction gain sharing and photonic integrated circuit-based technology.

“Infinera’s innovative ICE6 technology was selected to upgrade our system because it enables us to extend the life of the Unity Submarine Cable System while providing the highest level of quality for our customers,” said the Unity consortium. “The Unity Submarine Cable System is a critical connection between two continents with the fastest growing bandwidth needs. We needed an industry-leading solution that would enable us to be competitive now and in the future.”

“The Unity Submarine Cable System is one of the highest capacity underwater fiber optic cables ever built between Asia and North America, and Infinera is proud to power it with our latest optical engine technology,” said Nick Walden, Senior Vice President of Worldwide Sales at Infinera. “The increased capacity will help operators in Asia and the U.S. meet the increasing bandwidth demands on both sides of the Pacific.”
