Record 3.2 Tbps Data Transmission

Tuesday, 10 April, 2001

Siemens has broken what it claims is a world record for data transmission capacity by transmitting 3.2 Terabits per second of traffic on standard optical fibre under real conditions.

The record breaking data transmission rate was achieved using DWDM (dense wavelength division multiplexing) technology across a standard optical fibre network of global telecommunications carrier Worldcom.

Previously, Siemens had set the world record of 7 Tbps under laboratory conditions.

However, this new world record is the fastest data transmission rate under live conditions and doubles the previous highest transmission rate achieved under live conditions by Siemens.

Using existing WorldCom fibre network routes in the Dallas, Texas, metropolitan area, the carrier deployed 80 wavelengths of 40 Gbits per wavelength for a total capacity of 3.2 Tbps, using the Siemens TransXpress Infinity DWDM platform.

Siemens has built one of the world's largest DWDM networks, stretching from Cairns to Perth, and spanning almost 6000 km.

This network supplies the transmission infrastructure that carries all Australian IP traffic and the vast majority of the nation's phonecalls.
