Morning refreshments & exhibition viewing


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 and 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.  

New systems, new players: how will they be regulated?

  • Emerging regulatory issues on the horizon
    • Lessons from the Jones Act – how can the industry take a more proactive stance in addressing such “threats”
    • What are the potential pitfalls or challenges for the industry with today’s governments increasingly implementing protectionism measures?
  • Commercial issues with open cables
    • What are the possible issues that regulators will be concerned over, and how can we minimise potential red tape?

With greater capacity comes great(er) costs? - Managing cost limitations with increments in capacity

  • What are the existing challenges that come with increasing capacity limits of today’s subsea networks? (e.g. maintaining power efficiency)
  • Takeaways from Nokia-Facebook PCS trial
    • How will this drive down pressure on overall operations and construction cost?
  • What do you hope to see from supplier offerings?

ICPC Update: Competition & co-existence with other seabed users

  • How are developments in subsea mining, renewable energy use and MPA growth affecting the way we use the seabed?
  • How will this affect the way we plan for new submarine cable builds and maintain our cables?
  • Updates on BBNJ Prep Com

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?

Panel discussion: The changing geopolitics of submarine cable builds

  • How are current geopolitical relationships affecting the laws of the sea, and in turn, how we build cables?
  • Coping with political risk – how does this affect project timelines and financing? What can cable owners do to mitigate this risk?
  • How can the industry address this issue together?

Panel: Going beyond today’s capacity limits for tomorrow’s Internet

  • Evaluating what we have vs what we need – how are today’s hardware capabilities holding up?
  • Programming smarter, more agile and flexible networks – what are the existing challenges?
    • Next-gen coherent technology – what can we expect (or hope for) with advancements in technology?
  • Maximising the potential of virtualised networks

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?

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

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


Health check – considerations and challenges for cable health monitoring

  • Understanding the challenges that can affect the health of the cable
  • Capturing timely data in order to understand the state of the cable
  • Developing and implementing a proper mechanism to check the health of the cable in order to avoid cable failure

Applications of Machine learning, big data and AI in performance monitoring

  • What are the key challenges facing undersea network monitoring systems today?
  • How will emerging technologies help to ease the burden of performance monitoring?
  • With optical networks becoming more complex, what’s the way forward in deployment of these technologies for the subsea network?

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.

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

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)

Critical factors for data centre resiliency

  • With data centres increasingly serving as landing points, what new considerations must be given to ensure 24/7 reliability?
    • Security, power, what else?
  • What are the existing challenges and how can they be overcome?
  • Building and designing data centres of the future: what we can expect?

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?
