Bell Labs Demonstrates 606Gbps Transmission Using Optical OFDM

Bell Labs, research division of Alcatel-Lucent, used an optical orthogonal frequency division multiplexing (OFDM) to demonstrate a 606 Gbps line rate transmission. The demonstration was mentioned in a paper that was presented at the European Conference and Exhibition on Optical Communication (ECOC). The conference was conducted last month in Turin, Italy.

The optical orthogonal frequency division multiplexing transmission covered a distance of more than 1,600 km of fiber. According to Alcatel-Lucent, the system utilizes OFDM and PDM 32-QAM subcarriers and identifies the overall 606 Gbps multiplex in one-detection step.

The head of Alcatel-Lucent’s Bell Labs Research Center, Gee Rittenhouse stated that the next-generation optical transmission record will transform the communication network, which will allow the company to keep up with the future demands.
