Verizon and Nokia Siemens Networks Test 100 Gbps Transport

Verizon and Nokia Siemens Networks claimed a new optical transport record -- a 100 Gbps transmission on a single wavelength for more than 1,040 kilometers over field fiber. The test, conducted on optical fiber on the Verizon network in north Dallas, 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.


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 with significantly better chromatic dispersion and polarization-mode-dispersion tolerances than conventional systems.


"As a leader in pursuit of 100 Gbps technology, Verizon's goal is to drive optical networking to deliver greater capacities over longer distances to enhance the high performance and high bandwidth of our network," said Mark Wegleitner, Verizon senior vice president for technology. "Whether it's FiOS delivering HD channels and video on demand or business customers using database applications and online trading, we strive to provide the most advanced underlying network technology for our customers."


The technical details of this field trial were presented at the European Conference on Optical Communications (ECOC) by Verizon's Glenn Wellbrock, director of backbone network design, as an invited paper from Verizon Communications, Nokia Siemens Networks, Siemens PSE DE GmbH & Co. KG, Technical University of Eindhoven, and the University of the Federal Armed Forces.http://www.nokiasiemensnetworks.comhttp://www.verizon.com
