Telstra adds 800G to EAC-2A1 submarine cable via Infinera

Oct. 14, 2021
The dispersion managed undersea system runs 2,940 km between Hong Kong and Singapore and is now leveraging ICE6 800G capabilities implemented through Infinera’s GX Series Compact Modular Platform.

Infinera (NASDAQ: INFN) and Telstra say that the Australia-based carrier has deployed 800G capabilities on the EAC-2A1 submarine cable. The dispersion managed undersea system runs 2,940 km between Hong Kong and Singapore and is now leveraging ICE6 800G capabilities implemented through Infinera’s GX Series Compact Modular Platform (see "Infinera adds ICE6 to Groove (GX) Series").

The use of the 800G technology enables a 45% increase in capacity for a total capacity that is 20X the original design capacity, the two companies state.

“Telstra designed and deployed its dispersion-managed cable, EAC-2A1, long before coherent transmission was developed. The success of our ICE6 trial illustrates that we can successfully upgrade our existing cable systems to meet growing bandwidth demands,” said David Robertson, Executive International Networks & IT at Telstra. “This success was the driving force behind selecting ICE6. With Infinera’s 800G solution, we can significantly increase capacity on all segments of our network across our new modern and legacy cables globally. Building new cables is expensive, so getting the most out of them using the latest technology means we can meet our customers’ ever-increasing capacity and resilience needs at the right price point.”

“The success of this trial with Telstra and its decision to deploy ICE6 emphasize the innovative technology, capability, and value of ICE6, which demonstrated its ability to deliver scalable capacity across a challenging legacy cable,” said Nick Walden, senior vice president, worldwide sales, at Infinera. “As subsea operators look to protect their subsea network infrastructure investment, deploying proven solutions that quickly and cost-effectively enable accelerated service turn-up will be critical to meet increasing customer demands.”
