SEPTEMBER 2, 2008 -- Danish mobile and ISP service provider company Sonofon has improved its capacity and service offering with its first installation of 10G CWDM single-fiber equipment from Transmode (search for Transmode).
Sonofon, which has been a long-time customer of Transmode equipment, is owned by Telenor, one of the major telcos in Scandinavia, with mobile operations in 12 countries worldwide.
Sonofon says it began using Transmode's TM-Series of WDM equipment in 2005, when Transmode was awarded a Telenor contract in Norway, which was extended across the whole of Scandinavia. When Sonofon this year decided to increase network capacity to 10G, it selected Transmode's 10G CWDM equipment. Sonofon employs both single-fiber and fiber-pair configurations of Transmode's TM-Series, giving it the widest possible range of network topology options.
Â
Sonofon is one of the first customers to introduce and operate Transmode's bi-directional 10G CWDM single-fiber configuration--a key advantage of the Transmode TM-Series. The TM-Series is a family of carrier-grade optical transport products that provide the transport of any service between 100 Mbits/sec and 10 Gbits/sec in multi-reach transport applications, say Transmode representatives.
Â
Transmode claims to lead the industry in its use of pluggable optics. Prior to 2006, CWDM was restricted to a transmission rate of 2.5G, while 10G was only available over DWDM. In early 2006, Transmode says it was the first company to introduce CWDM optics operating at 4G and, in December 2007, 10G CWDM channels. As a result, it is now possible to upgrade a CWDM network to 4G or 10G by the addition of the relevant muxponder or transponder, say company representatives.
Â
"This development by Transmode enables the development of a network based on the most economical CWDM setup while still allowing an upgrade path to 10 Gbits/sec," explains Björn Andersson, vice president of sales at Transmode. "Previously, you would have needed to deploy a more expensive DWDM solution to have this upgrade path. So we believe this development is a real killer app."
 Â
"We are very pleased with the newly installed Transmode technology and dedicated network backbone," confirms Sonofon's operations manager Michael Danielsen. "Our choice of Transmode--and particularly for the new single-fiber 10G CWDM--reflects both Sonofon's and Telenor's confidence in Transmode as a forward-thinking and reliable supplier."
