Australia Japan Cable trials Infinera's advanced coherent algorithms for next-gen optical engines

SAN JOSE, Calif. – Infinera (NASDAQ: INFN), announced today Australia Japan Cable (AJC) is the first to trial Infinera's advanced coherent algorithms for next-generation optical engines. The evolution of advanced signal processing algorithms is critical to continuing to drive down the cost and power per bit of transmission as well as increasing capacity per fiber. The trial was conducted over a 7,289-km segment of the AJC cable system between Paddington, New South Wales, Australia and Tumon Bay, Guam. The trial delivered a 17% increase in total fiber pair capacity compared to the current generation of optical engine deployed in AJC's network.

The AJC cable system was brought into service in 2001 with a design life of greater than 25 years. Its design predates the introduction of coherent transponders by almost a decade. Capacity growth in the Pacific region is around 35-40% per year, making the increase of capacity on submarine cables more critical than ever.

This trial leveraged Infinera's advanced development testbed used for comparative algorithm testing, which included a high-performance arbitrary waveform generator-based transmitter, a receiver based on high-performance photodiodes, and a real-time oscilloscope. The trial tested advanced modulation, forward error correction (FEC), and nonlinear compensation algorithms.
