Commercial Deployment of 100 Gbps Service Is One Step Closer as Result of Successful Field Trial

BASKING RIDGE, N.J., Sept. 25 /PRNewswire/ -- Verizon and Nokia Siemens Networks have taken a step closer to being able to transmit commercial traffic at a speed of 100 gigabits per second (Gbps). The two companies carried out a successful 100 Gbps transmission on a single wavelength for more than 1,040 kilometers over field fiber, setting a new distance record and demonstrating better performance than conventional transmission.

The field trial, conducted on optical fiber on the Verizon network in north Dallas, successfully proved that 100 Gbps signals can be simultaneously transported with 10 Gbps and 40 Gbps signals on the same system with superior results by using advanced optical techniques.

The Nokia Siemens hiT 7500 ultra-long-haul, dense-wavelength-division-multiplexing platform -- combined with multi-level modulation, polarization multiplexing and coherent detection -- allowed the signal to be carried over ultra-long distances at high-data rates with significantly better chromatic dispersion and polarization-mode-dispersion tolerances than conventional systems.

The field trial also demonstrated that 100 Gbps traffic can be simultaneously transported with any mix of 10 Gbps and 40 Gbps on a typical 80-channel ULH DWDM system. As a result, current network configurations can support capacity upgrades to 100 Gbps per channel on existing routes over similar distances without modification to the physical network, providing quicker, cost-effective implementation.

Like Verizon's previous 100 Gbps trial in late 2007, this field trial also carried the 100 Gbps signal on a single wavelength, demonstrating true 100 Gbps throughput in a serial configuration. In this field trial, the modulation technology enabled an even higher total system capacity of 8 terabits per second. A terabit is one trillion bits.
