Verizon and NEC reported a new record for optical transmission: the companies were able to transmit 40.5 terabits per second (Tbps) for a long-haul distance of more than 1,800 kilometers (1,118 miles) and 54.2 Tbps over a regional distance of more than 630 kilometers (391 miles), using Verizon’s fiber loop outside Dallas. The DWDM system used both the C-band and the L-band.
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.
“Successful scientific accomplishments such as this demonstrate that Verizon is taking major steps to advance the industry’s understanding of high-capacity optical technology,” said Ed Chan, vice president of network technology for Verizon. “Verizon continues to address the challenge of maximizing performance on our global network while providing lasting business value and best-in-class services for our customers.”
