Banverket and Nortel Trial 40G/100G on live fiber network

Banverket ICT says it has completed a successful live field trial, running 10G/40G/100G simultaneously on its existing fiber network between Sundsvall and Stockholm, using a Nortel optical solution. The trial, completed in April over a total fiber distance of 810 km, is the first live trial of its kind in the Nordic region, says the company.
Banverket ICT is one of Sweden’s largest suppliers of network service.
It is a subsidiary of Banverket, the authority responsible for Sweden’s
railways, which operate a transport and communications network running
alongside the country’s 13,000-km rail network. Banverket ICT provides
network services for Banverket and also sells extra capacity to major
service providers, government agencies and companies such as Sweden’s
largest cable TV operator, Com Hem.
The trial demonstrated that Nortel’s 10G/40G/100G scalable solution can
increase the variety and reach of Banverket ICT’s flexible capacity
network services. The company currently offers network bandwidth
ranging from 2Mb/s to 10Gb/s.
The live 100G trial used Nortel’s 40G/100G Adaptive Optics Engine to
test a mix of 10G, 40G and 100G wavelengths over an existing 10G
engineered link of five spans without regenerators or external fiber
compensators. The tests showed successful 100G operation under fiber
stress conditions that would occur under normal operations. Banverket
ICT already delivers 10G services in Sweden and the trial has shown
that their optical network can be scaled simply and cost effectively
from 10G to 40G and 100G.
