Coherent Communication Market Forces and Network Evolution

Coherent communication has become the front runner of next generation optical networks. Already dominated long-haul networks, it is now competing with direct detection in short-reach applications. This talk addresses the following topics: • Coherent scaling trends from long-haul to data centers • Direct or coherent detection for short reach 800G and beyond • How to use technologies that have been used for long-haul for short-reach applications • Co-packaging optics and processors.
