Real–time adaptive coherent heterodyne detector for future optical netowrks (TCHATER) — ANR Télécommunications

Participant : Frédéric Cérou.

INRIA contract ALLOC 2801 — January 2008 to December 2010.

This ANR project is coordinated by Alcatel–Lucent. The other partners are E2V, TELECOM ParisTech, LIP (ENS Lyon).

The primary goal of the TCHATER project is to demonstrate a coherent terminal operating at 40Gb/s using real–time digital signal processing and efficient polarization division multiplexing. The terminal will benefit to next-generation high information-spectral density optical networks, while offering straightforward compatibility with current 10Gbit/s networks. It will require that advanced high–speed electronic components, especially analog–to–digital converters, are designed within the project. Specific algorithms for polarisation demultiplexing and forward error correction with soft decoding will also have to be developed.
