Infinera claims new optical platform could halve telcos' electricity bills

Infinera released a new optical switching platform designed to help network operators deal with growing bandwidth demands, and revealed that it is being trialled by pan-European network operator Interoute.

Speaking to Total Telecom ahead of the announcement, Interoute highlighted the need for cheaper networking solutions as bandwidth consumption continues to grow.

"The end user is fickle, [and] is always coming up with new ways to use bandwidth," said Robin Tero, service provider and services development director at Interoute.

"[There is] not much margin on [selling bandwidth] so we'll sell volume," he added, noting that a growing trend for service providers to outsource backhaul to companies like Interoute is adding to demand. "We cannot build network fast enough to meet demand when [each channel] is 10 gig," he said.

However, Interoute has yet to commit to buying the new Infinera platform. Tero said the company is awaiting the results of trials with the new technology, which "[if] the price is right... [is] one of the platforms we're considering."

"We've done some early trials," Tero mentioned, referring to a demonstration of Infinera's 500-Gbps PICs between London and Amsterdam in March. "That was with live traffic," Tero added. "[We'll now] start trials with this new platform."

However, the unit price is not Interoute's main concern. "[Operational cost], that's the hardest to control," Tero said. Power, space, and employees are all recurrent costs every year. Any saving makes expanding the network more affordable, he said.

Meanwhile, Geoff Bennett, director of solutions and technology at Infinera, explained how the new hardware can create these savings.

The DTN-X is a network switch, which can also convert electrical and optical signals. "[We] do not trade off transition capacity for switching capacity," he said.

Infinera's DTN-X has 10 slots, each containing 5 channels that utilise its 100-Gbps PICs, a tenfold improvement on the standard 10-Gbps channels Tero referred to earlier. That means that in total the DTN-X can operate at 5 Tbps.

With the DTN-X network providers can "use less power, [and] take up less rack space," Bennett said. "[It] makes the conversion between optical and electric a lot more cost effective."

The new hardware will also scale in the future, Bennett added. "We can double PIC capacity every three years," he said, noting that by doubling the capacity of the PICs the DTN-X could operate at 10 Tbps. In fact, this next iteration of the technology is already under development, Bennett said.
