Title: Verizon and Nokias Siemens Network: 100G field trial Post by: RealWire on September 16, 2008, 09:12:54 PM When: September 25, 2008 at 11:45 a.m. CEST
Where: ECOC 2008 - Brussels, Belgium Who: Glenn Wellbrock, Director, Optical Transport Network Architecture and Design, Verizon Background: A major milestone has been achieved with 111 Gbit/s Optical Networks deployed over a distance of 1,040 kilometers September 16, 2008 - At the European Conference on Optical Communication (ECOC) Verizon and Nokia Siemens Networks will present a common paper on 100 Gbit/s optical networking based on a field test in Verizon’s network. The test involved the transmission of wavelength channels carrying multiple data rates (10 Gbit/s, 40 Gbit/s, 100 Gbit/s) over 1,040 kilometers on deployed fibre -- an industry first. In March 2008, Verizon and Nokia Siemens Networks completed a successful field trial demonstrating the 111 Gbit/s approach. The test involved the insertion of 111 Gbit/s channels in spectral positions that are adjacent to other channels carrying 10 Gbit/s and 40 Gbit/s data rates, with a line system that had only been designed for 10 Gbit/s transmission. The 111 Gbit/s used advanced optical techniques allowing a 100 Gbit/s data channel to occupy a very narrow spectral width and to accommodate spacing between channels of only 50 GHz, resulting in a total useable capacity of 80 channels. The trial also demonstrated that 100 Gbit/s traffic can be simultaneously transported with any mix of 10 Gbit/s and 40 Gbit/s on a typical 80-channel system. As a result, current network configurations can support capacity upgrades to 100 Gbit/s on existing routes over similar distances without modification to the physical network, providing quicker and more cost effective implementation. Like Verizon’s previous 100 Gbit/s trial in late 2007, this trial also carried the 100 Gbit/s signal on a single wavelength, demonstrating true 100 Gbit/s in a serial configuration on just one transmission wavelength. (The paper was commonly written by Verizon, Nokia Siemens Networks, TU Eindhoven and the University of the German Federal Armed Forces in Munich) |
