The PSE chip was developed in Alcatel-Lucent's Bell Labs research facility. According to the company, the PSE is designed to be the building block that can add capacity to networks without laying more fibre-optic cable in the ground. Indeed, the PSE enables more than 23 terabits of traffic to be transmitted among one optical cable compared to 8.8 terabits in a 100Gb network.

The 400Gb chip, unveiled on Tuesday, comes just 20 months after the 100Gb transport semiconductor arrived from Alcatel-Lucent. The PSE can be deployed in metro, regional and ultra-long haul networks.
