AT&T, NEC, Corning test 32 Tbps connection

AT&T and vendor partners NEC America and Corning have worked together to test 32 Tbps transmission over a 580-km fiber link. The transmission was executed at 114 Gigabits per second over each of 320 separate optical channels on the single fiber to reach the aggregate bandwidth, according to an AT&T press release. The test originally was discussed at OFC/NFOEC in San Diego, Calif.

AT&T said the research was driven by the carrier's ongoing IP traffic growth rate of 45 percent annually. The test also is the latest step in efforts by a variety of carriers to demonstrate higher backbone bandwidth capabilities.
