Verizon & NEC Claim Fiber Record

NEW YORK -- For the third consecutive year, Verizon and NEC Corporation of America announced they have set an industry record, this time by successfully sending the highest-capacity transmissions for regional and long-haul distances over field fiber.The achievement was accomplished by tightly packing optical channels in two bands of the optical fiber spectrum. Previous field transmission trials used a single optical band. By expanding from one band to two bands -- the C-band and the L-band -- Verizon and NEC were able to transmit 40.5 terabits per second (1 terabit equals 1,000 gigabits) for a long-haul distance of more than 1,800 kilometers (1,118 miles) and 54.2 Tb/s over a regional distance of more than 630 kilometers (391 miles), using Verizon’s fiber loop outside Dallas.The results of the latest trial, performed in late 2012, were accepted and presented as a post-deadline paper at the OFC/NFOEC Conference and Expo last month in Anaheim, Calif.Verizon Communications Inc.
