Optical Networks – Will they destroy the planet or save humanity?

Details are subject to change.

  • Organisers

    Chris Fludger, Infinera GmbH, Germany
    Fabrice Bourgart, Orange Labs, France

  • Subcommittee

    SC4 – Techniques for Digitally Enhancing Optical Communication

  • Day & Time

    18.09.2022, 14:00 – 17:30

  • Location

    Room San Francisco

  • Description

    Exponential growth is not sustainable, and the once long-term problems of climate change are becoming rapidly short-term problems affecting resource depletion, waste generation, general pollution and increasing prevalence of natural disasters. This workshop examines the green credentials of the optical communications industry, and looks at initiatives and directions towards a more sustainable future.

    Today’s networks focus on high-end performance and end-user experience. Tomorrow’s networks must also balance energy efficiency with varying traffic-load, and designs focused on sustainability.

    The workshop precedes the Nobel plenary talk of Didier Queloz on Exoplanet Discovery, and in contrast to traditional ECOC workshops, will be open to the general public. There will be plenty of opportunity for thought-provoking discussion and questions!

  • Posed Questions

    Introduction

    The Big-Picture, Klaus Grobe, Senior Director Global Sustainability, ADVA Optical Networking SE, Germany
     How long is exponential growth sustainable?
    An end-to-end view: Where should we focus our efforts for the biggest savings and improvements? Data-center, Access or Metro? FTTH?
    Does Greening-by-ICT make the Optical Telcom industry look good or bad?
     Who is doing what, and will it make a difference? 

    Re-use, Reduce, Re-cycle, Florian Doussot, Orange Sustainable and Circular Ambition for Recertification (OSCAR) Stream Leader, Orange, France
    What’s going on in improving product life-cycle?
    Are pluggable devices the answer to re-use and extending the lifetime of optics, or are we creating a landfill of disposable devices?
    Are our efforts for a circular economy running in circles?
    Should we be using Indium-Berylium-cyano-non-recyclium?

    Give me Moore for less!, Kishore Kota, Associate Vice President Engineering, Coherent DSP Group, Marvell, USA
    What progress have we made in reducing power consumption for optical transceivers and ASICs?
    Will Moore’s law save us? What’s the limit?
    How can we optimize power through design? How much power remains in the optics? What can we save?
     Optimising power depending on traffic load?
     Game-changers?

    Power consumption is Over-The-Top
    What are the power-hungry applications and services? IOT? Streaming? Machine learning? What is the traffic characteristics? Latency? Burstiness? Throughput?
     Is disaggregation beneficial for cost or power?
     Bandwidth as a limited resource?
     PON = Power-efficient Optical Networks?
     What are the game changers ? Will Optical switching make a dramatic difference?
     Network architecture for lower power rather than higher performance?

    A disruption in the network, Johan Bäck, Sr. Director, Business Development, Infinera, Sweden
    The need for a simpler more intelligent network.
    Lowering power with lower traffic-load?

    Big-Data vs Intelligent Data, Dan Kilper, Professor of Future Communication Networks, CONNECT centre, Trinity College Dublin, Ireland
    Optimising networks for lower energy rather than higher performance. Are they mutually exclusive?
    Does network disaggregation spread the flames?
    Big Data & centralized AI, or limited data & Distributed AI?
    Are we a slave to legacy IP? Kill off transcoding?
    Today’s networks seem less-and-less aware of the end-to-end application.
     Any game-changers?

    Are Optical Networks the Solution for Energy Hungry Data Centers?, Chongjin Xie, Senior Director, Chief Communication Scientist, Alibaba Cloud, USA
    Moving towards bandwidth/power on demand – energy optimisation for traffic loads
    Designing the network to lower the impact of power hungry applications
    Designing for resilience in an energy constrained environment
    Data-center architectures focused on lower energy rather than higher processing
    Key technologies
    Life-time and re-use of pluggable devices in a data-center

    Are we willing participants or do we need to be dragged screaming to the table?, Jean-Luc Lemmens, Director, Media and Telecom, IDATE, France
    Do we as end-users / service-providers / manufacturers have enough incentive to lower energy usage?
    Who will set the goal to be achieved?
    What sacrifices will we have to make?
    How to achieve awareness and co-operation across different segments?
