Nokia shares its vision for cost-reduced coherent optics

Nokia explains why coherent optics will be key for high-speed short-reach links and shares some of its R&D activities. The latest in a series of articles addressing what next for coherent.

Part 3: Reducing cost, size and power 

  

Coherent optics will play a key role in the network evolution of the telecom and webscale players.

The modules will be used for ever-shorter links to enable future cloud services delivered over 5G and fixed-access networks.

Tod Sizer

The first uses will be to link data centres and support traffic growth at the network edge.

This will be followed with coherent optics being used within the data centre, once traffic growth requires solutions that 4-level pulse-amplitude modulation (PAM4) direct-detect optics can no longer address.
