NEC Corporation announced about a new record for communication using 1.15-Tb/s ultra-long haul optical transmission over 10,000 kilometers using optical superchannel technology. In total, four lasers were used simultaneously to transmit 4Tbps down a single optic fiber.

According to The Verge, NEC's network reached speeds of 1.15Tbps and traveled over 10,000 kilometers; multiple superchannels were also combined for a total speed of 4Tbps.

The Verge also added that Superchannels have been in the works for a few years, and NEC's work doesn't look revolutionary — experiments by other groups have been able to reach terabit speeds at up to 10,000 km.
