Telstra International takes 40G plunge with Infinera

Tools

Telstra International (ASX: TLS.AX) has put Infinera's (Nasdaq: INFN) 40G DTN solution to work in its optical subsea network in Asia, making it the optical vendor's hundredth customer.

The 9,000 km deployment spans four countries, including Hong Kong, Taiwan, Japan and South Korea.

A key point of this deployment, explained Martijn Blanken, Telstra International Group chief operating officer, is about flexibility to scale the existing network beyond 40G as needed.

"We are confident we have invested in a network that will accommodate the needs of our customers now and into the future," Blanken said. 

The DTN will allow Telstra International to upgrade its existing submarine cables with both coherent 40G wavelengths supporting its software-based FlexCoherent technology. FlexCoherent enables service providers to choose between coherent polarization-multiplexed binary phase-shift keying (PM-BPSK) and quadrature phase-shift keying (PM-BPSK) and quadrature phase-shift keying (PM-QPSK) when deploying 40 and 100 G links.  

Later, Telstra could upgrade the submarine cables to 100G FlexCoherent, including Soft Decision Forward Error Correction, which will deliver 7.3 Tbps of capacity over Telstra's Reach North Asia Loop (RNAL) fiber plant when capacity demands dictate such a move.

Having the flexibility to migrate to 100G optical on existing fiber networks is a key element for service providers like Telstra International who are trying to stay ahead of a growing set of multinational business and wholesale customers whose bandwidth needs aren't showing any signs of slowing down.
