Verizon, NEC claim fiber speed records
Verizon and NEC said they have successfully sent the highest-capacity transmissions for regional and long-haul distances over field fiber.
The two companies said tests showed that by expanding from one band to two bands, the C-band and the L-band, the two firms were able to transmit 40.5 terabits per second 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 achievement was accomplished by tightly packing optical channels in the two bands of the optical fiber spectrum, the two firms added.
Verizon and NEC also claimed to have set an industry record for the third consecutive year. 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, California.
The ability to use current field fiber to carry higher capacity rates enables carriers to avoid the need to deploy new fiber and, as a result, better utilize current network infrastructure, Verizon said.
Verizon added that increased capacity demands are driven by video services, wireless applications, real-time gaming, data storage and IP services – as well as network providers continue to look for ways to meet that demand without performing large scale infrastructure upgrades.
