Telstra will upgrade the capacity of three of its ultra-long-haul subsea fibre optic cables spanning across from Australia into Asia and the United States.

The company announced overnight that it will upgrade the Infinera DTN-X platform to allow the telco to deploy 10G, 40G, and 100G Ethernet and optical transport network (OTN) services on its 9,000km Endeavour cable connecting Sydney and Hawaii; the 9,000km Reach North Asia Loop cable connecting Hong Kong, Korea, Taiwan and Japan; and the Asia America Gateway cable connecting Hawaii with California.

The DTN-X technology expands a cable's single-line capacity to 500Gbps, with future upgrades to allow for up to 1Tbps per line.

Telstra Global's chief operating officer Darrin Webb said that the upgrade would help Telstra meet the speed and capacity requirements of customers in this region.

"We are continually developing our network to meet customers' requirements, and this is just one of the projects we are working on to ensure our network is always growing, improving, and providing world-class services," Webb said in a statement.

In 2012, Telstra first upgraded the Reach cable to the DTN platform.

Infinera's chief technology officer and president David Welch said that the DTN-X was designed to allow for future upgrades to terabit super-channels and terabit Ethernet.

Last week, Infinera announced that the Australian-Japan Cable (AJC) would also be upgraded with the DTN-X technology.
