Alcatel-Lucent completes 400G field trial with Australia's Nextgen

Alcatel-Lucent (Euronext Paris and NYSE: ALU) has completed a successful field trial of 400-Gbps data transmission over an existing optical link carrying live network traffic belonging to Australian network services provider Nextgen.

Alcatel-Lucent (Euronext Paris and NYSE: ALU) has completed a successful field trial of 400-Gbps data transmission over an existing optical link carrying live network traffic belonging to Australian network services provider Nextgen.

The trial was conducted over a 350-km route between Sydney and Canberra using Nextgen’s newly commissioned high-capacity 100G optical transport network delivering services up to 100 Gbps. The technology behind the trial was based on Alcatel-Lucent’s 1830 Photonic Service Switch PSS with the 400G Photonic Service Engine (PSE).

“It was our first 400G DWDM demo in the Asia-Pacific region and, unlike those of our competitors, it was carried out over a live network,” said Sean O’Halloran, Alcatel-Lucent Australia president and managing director.

Using Alcatel-Lucent’s 400G technology, the trial demonstrated the ability of an existing fiber-optic network link to transmit up to 17.6 Tbps. The trial demonstrated wavelength transmission rates roughly double those possible over an existing 100G coherent network, demonstrating the capability to double the transmission capacity in the future.

Nextgen is currently undertaking a major upgrade to its high-capacity optical network, which is optimized for services at 100G (see "Alcatel-Lucent, Nextgen Networks demonstrate 100 Gbps connectivity"), while it explores technologies to meet significant new service and customer capacity demand anticipated in coming years. Alcatel-Lucent says the ability to simultaneously support 100G and 400G services over a live network demonstrates how network operators can successfully manage the transitions required to support these future demands.

“This successful 400G trial over a live network is another indication of our commitment to stay at the leading edge of optical transmission technology and our confidence in the equipment we have chosen,” said Phil Martell, CTO, Nextgen Group. “Nextgen is in the midst of a major network upgrade to all Australian capital cities with a high-speed optical network optimized for services at 100G and higher, and providing increased flexibility and manageability. The trial is an important step on the path to offering our customers the differentiated services they want in the fastest and most economical way.”

Alcatel-Lucent’s adds that the trial also successfully demonstrated Agile Optical Networking with adaptive 100G/200G/400G optical transmission on a live network showing that the live optical channel successfully adapted to different speeds, distances and spectrum.

Alcatel-Lucent says its success with Nextgen is the latest in a series of successful 400G trials conducted this year in Europe and North America. Earlier this year, those field trials led to what the vendor claims is the first commercial deployment of 400G in live network with Orange for French research and education network operator RENATER (see “Orange, Alcatel-Lucent provide live 400G link to RENATER”). In September the vendor carried out a live field trial with Canadian operator SaskTel (see “SaskTel trials 400-Gbps optical transport on live fiber link with Alcatel-Lucent”).
