Panel IV: Evolution to Coherent WDM Integration in Routers

Wednesday, 09 June 15:30 – 17:00

Moderator: Helen Xenos, Ciena, Canada

Panel Description:

The miniaturization of electro-optics and advancements in CMOS that enable lower power / footprint are enabling the deployment of coherent optics in smaller pluggable form factors and across new areas of the network. These advancements bring with them new opportunities in deploying switches/routers with integrated or coherent pluggable optics, also known as IPoDWDM architecture. In particular, emerging 400G pluggables are expected to bring significant CAPEX and OPEX savings for DCI networks.

In planning of network and architecture evolution, the following questions arise:

  • Do coherent pluggables eliminate the need for optical transport equipment from the network?

  • Which applications are better served by switches/routers and which by optical transport platforms?

  • What are the power vs performance tradeoffs in using coherent pluggables?

  • Does the role and architecture of the photonic layer change with IPoWDM networks?

  • How important is line interworking versus higher performance bookended coherent pluggables?

  • What have we learned as part of the standardization efforts led by ITU, OIF, IEEE, OpenROADM, and CableLabs?

  • Beyond the optics, are there additional operational aspects, such as interaction with the photonic layer, that are required for viable deployment across a wider range of applications?

  • How will the new architecture impact optical SDN controllers? Would they be managed by router controllers, or will a combination of both be used for connecting to a co-existing network of optical platforms?
