Telstra and Infinera go over a mile for Hawaii-California submarines
Infinera's indium phosphide (InP) PICs have crossed 4,200 km across the Pacific
Infinera has successfully demonstrated a 100 Gigabit per second (Gb/s) optical signal enhanced with Soft Decision Forward Error Correction (SD-FEC) across Telstra Global's dedicated fibre pair within Segment S5 of AAG Hawaii to California submarine cable.
Infinera says this D-FEC technology has the potential to double the transmission capacity of existing submarine cables. This trial demonstrates the power of SD-FEC in concert with Infinera's long haul FlexCoherent super-channel technology and how it can optimise both reach and capacity on submarine cables worldwide.
The subsea trial was performed over Telstra Global's fibre pair within Segment 5 of the AAG cable, connecting San Luis Obispo in Southern California to the island of Oahu in Hawaii and spanning 4,200 km across the Pacific.
The trial was staged using Infinera's DTN-X platform and a prototype super-channel line card enabled with Infinera's 3rd generation FlexCoherent Processor for real time SD-FEC processing combined with the InP based 500 Gb/s Photonic Integrated Circuits (PICs).
Using the additional error recovery capability enabled by the SD-FEC, multiple Infinera FlexCoherent modulation formats were able to close this link with no bit errors detected. The SD-FEC enabled higher order modulation formats to be used which could allow Telstra to increase the available capacity on this link increasing the commercial life of the cable in the face of aggressive increases in internet demand.
A key characteristic of Infinera's FlexCoherent technology is that the line card can be configured for a specific modulation format via simple software controls, increasing flexibility and maximising capacity and reach while lowering operational and inventory sparing costs.
Telstra Global is a part of Telstra Corporation Limited, one of Australia's leading telecommunications and media services company and owner of one of the most technologically advanced IP backbone networks in the world.
Telstra's dedicated fibre pair within Segment S5 of the AAG submarine cable is part of a system of cables linking the powerhouse economies of Australia and the Far East to the West Coast of the United States. Telstra Global forecasts more than 60 percent annual growth in its trans-Pacific submarine cable traffic over the next three years.
Telstra Global Managing Director, Martijn Blanken says, “We are delighted by the results of this field trial and this shows further increased capacity potential for Telstra Global's leading submarine cable plant. Our continuing focus on cutting edge technologies will enable us to continue to deliver new services to our customers and meet their future capacity needs with a long term, reliable offering.”
Infinera co-founder and Chief Strategy Officer, David Welch adds, “We are pleased to see that our 3rd generation FlexCoherent Processor along with 500 Gb/s PICs, is performing exceptionally in real world environments."
"Over the past few months we've shown that a PIC-based long haul super-channel implementation can deal with record-breaking levels of PMD impairments in fibre; deliver a full 8Tb/s of capacity on Dispersion Shifted Fibre that service providers might have written off as useless, and now with Telstra's help we've shown that with the addition of SD-FEC, this technology is capable of being deployed on some of the longest and most challenging cable routes in the world.”
