Bell Labs, the research and development arm of Lucent Technologies, has announced the first transmission of 10 channels of 107 Gigabit per second (Gb/s) data over 2000 kilometers of fiber, which the company says is a significant enough distance to prove the technology’s viability for the majority of networks where 100 Gigabit Ethernet is a sought-after technology.

The findings will be contained in a paper to be presented to the European Conference and Exhibition on Optical Communication (ECOC) in Cannes, France this week.

In it, researchers also announce the successful transmission and reception of electronically multiplexed and demultiplexed 107 Gb/s traffic using hardware similar to that used in today’s 40 Gb/s networks.

“An enormous amount of (our) research is focused on providing carriers with broadband network technologies that enable their metro area networks and backbones to support the dramatic increase in IP traffic by enterprise applications and consumer services such as IP-based video on demand,” said Martin Zirngibl, director of Bell Labs.

Data traffic is currently carried over the WDM backbone at rates of 10 Gb/s and occasionally 40 Gb/s using SONET/SDH or OTN connections.

The Bell Labs research is aimed at developing the technologies and architectures to enable carrier-grade wide area transport and switching of 107 Gigabit Ethernet data streams (100 gigabit of data plus additional 7% overhead for error correction).
