COHDEQ40 Project
Project COHDEQ 40 intends to demonstrate the potential of coherent detection associated 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.
