COHDEQ40

COHerent DEtection for QPSK 40Gb/s systems
Project COHDEQ 40 intends to demonstrate the potential of coherent detection, multi-level modulation format and the association with Digital Signal Processing for next generation high density 40Gb/s WDM systems optimized for transparency and flexibility. Key integrated optoelectronics components and specific algorithms will be developed and system evaluation performed

Coherent detection field has been an extremely active topic during the last 4 years. Demontrations have almost unlimited amount of chromatic dispersion, of PMD, and detection of polarization multiplexed format have been demonstrated thanks to advance digital signal processing algorithms. Transmission at 40Gb/s and 100Gb/s have been demonstrated over transoceanic distance. High performance optoelectronic components have been realized and evaluated in long distance transmissions.
