New market players, security threats and growing demands for protection of privacy are changing the way telecom regulators and policy makers are governing the telecommunications space. What are these changes, what’s at stake and how can the industry adapt to these changes? 


The need for higher capacity, faster networking and lower costs of power per bit has created new challenges and opportunities for our optical networks. Addressing these issues will require innovative approaches at every layer of the network. In this segment, we take a look at these new challenges and assess the approaches that have been taken.

    • Assessing the feasibility of the space-division-multiplexing technique for submarine cable systems
    • The case for network disaggregation to create greater scalability and flexibility – what are the commercial implications for cable operators/owners?
  • Maximising the potential of virtualised networks  

Closing Q&A – All hands in: Enhancing industry collaboration to ensure network resiliency and reduce risk

  • Assessing past and present: how has the working relationship between government and the industry changed, and what’s left to be desired?
  • With increasingly crowded waters, what are some ways that governments are managing multiple seabed users and/or collaborating to ensure critical communications infrastructure are protected?
  • What are some of the future potential threats you foresee to our critical comms infrastructure, and how can the industry and policy makers collaborate on minimizing them?

Networking lunch and exhibition viewing

New Routes and how to finance them

With new routes being deployed to ensure diversity and resiliency, how does this change or affect the business case and financial criteria for investment? We invite various subsea infrastructure financiers to discuss how their considerations have changed, how project financing has changed and new models to consider when investing in some of the world’s newest cable projects


Keeping submarine cables free from any defects have become increasingly critical, with our networks reaching the stage of being “too big to fail”. How can cable owners ensure that their cables are kept in constant good health, and minimize downtime by early detection of faults?

Panel: Financing tomorrow’s cables

  • Financing now vs then: how has it changed and what are the new trends that have emerged?
    • How are today’s financial markets creating an environment to promote subsea investment?
    • Examining the renewed/emerging interest from new financiers – what’s in it for them?
  • (for financiers) What criteria are you evaluating before making an investment decision?
  • How have cable operators/owners improved in structuring their finances in order to achieve project success? What are the areas that can be improved or made easier?
  • Looking ahead: how will tomorrow’s cables be financed?

Overcoming challenges of commissioning, turning-up and troubleshooting 100G networks and best practices for transceiver validation in submarine networks

  • Applicable standards for Optical-Signal-to-Noise Ratio (OSNR) measurements at 100G/200G
  • Why old OSNR methods do not work for 100G+ signals
  • Fundamentals of Ethernet testing including Service Activation Methodologies such as iSAM
  • Demystify the different types of optical interfaces including CFP4, QSFP28, QSFP+ and other pluggable transceivers and how to best troubleshoot issues or failures

Case Study – Testing methods for OSNR in open systems

  • Acceptance testing – where to begin?
  • What are the metrics to be agreed on (OSNR, gain profile, bandwidth etc) and what are (or will be) the challenges in coming to an industry standard?

(cont'd) Panel: Financing tomorrow’s cables

Route Planning & Marine Surveying

As cable owners look at building on new routes in order to create diversity and redundancy for their network, the functions of route planning and marine surveying become ever more critical in affecting the cable’s lifetime and reliability. In this segment, we explore the new challenges that have emerged, technological advances to enable success and building for harsh environments

(cont'd) Panel: Financing tomorrow’s cables


Reducing risk through your cable route study

  • How can cable owners better plan to ensure optimal routing between landing points?
  • Minimising risk caused by natural and/or manmade influences
    • E.g. Regulatory, competing seabed users, unexploded ordinance (especially for new routes)

Data Centres

As our networks have evolved from a beach-to-beach model, to POP-to-POP and now from DC-to-DC, the role of data centres and their relationship with the subsea industry has become even more intertwined. In this segment, we discuss this evolving relationship and project what’s to come in the next 5 years.

Facilitating an off-the-shelf cable landing system & permit in Marseille

Faced with the growth of data traffic and the need for higher network performances, the demand for submarine cable systems is steadily increasing. In response to this trend, Interxion and GPMM share a common goal towards the development of cable landing facilities in Marseille. GPMM acts as a neutral facilitator towards a pre-equipped and pre-authorized landing stations in the Marseille harbor area. By doing so, operators or consortium members could benefit from a neutral “ready to equip” infrastructure, with a pre-authorized permit already provided by the French authorities. In addition to save time, this solution allows an easy implementation in a secure and reliable environment managed with highly operational excellence standards. Mrs Cabau, Port of Marseille Fos CEO and Fabrice Coquio, President of Interxion France, offer to make a presentation of this project and to explain how Marseille has now become a strategic gateway for cable system operators


Case Study: Building for harsh environments

  • Lessons from dealing with anomalous weather, unique burial conditions and non-traditional seabed locations 
  • Balancing safety vs latency vs projected risks
  • Expectations vs reality: how much did actual installation conditions differ from desktop study and how were they overcome

Panel discussion: The era of land and sea convergence

  • How are today’s demands for connectivity, resiliency and 24/7 availability affecting the way we build and locate data centres?
    • Where are the new data hubs or regional hubs of connectivity that are being developed today?
  • How does this affect the way today’s networks are designed and deployed?
    • How are technologies such as SDN changing the way bandwidth is consumed and in turn co-location pricing models?
    • What are the physical and/or commercial constraints of extending the submarine network further inland?
  • How can the subsea cable owners and data centre operators work cohesively in facilitating the new digital economy?
    • What are the foreseeable challenges (e.g. regulatory) and how can they be overcome?

Submarine cable maintenance market – the next 10 years

  • Overview of the current marine services market
  • Existing challenges and new opportunities
