Xtera Communications, Inc. will be very active at SubOptic 2016 Conference to be held in the Conrad Hotel in Dubai, UAE (18-21 April 2016), with a large delegation (including executives and technical experts) and a strong presence in the technical conference program (the program can be downloadedhere). SubOptic 2016 event is hosted by E-marine PJSC and is the “must attend” event for the undersea communications community.
SubOptic 2016 Conference Masterclass Tutorial
Tony Frisch (SVP Repeater and BU, Product Line Management) will moderate the masterclass tutorial about optical Power Budgets, on Monday between 14:30 and 16:00. Optical power budgets are key to the supply or upgrade of any submarine system, yet they sometimes appear – or are made to appear? – complex and difficult to understand. In reality, the essential principles are not that difficult to understand, even if deriving some of the numbers requires sophisticated tools and experience. The objective of the tutorial is demystify the essential processes, explain what the numbers mean and to show when it is necessary to go beyond approximations that are often used.
SubOptic 2016 Conference Workshop
Tony will participate in the workshop about the extension of the life of submarine cable systems as well.
The move from regenerated submarine cable systems to optically amplified systems initiated a technologically dramatic paradigm shift as the dream to upgrade capacity from the landing stations (without touching the submerged cable and repeaters) became a reality. With this, and the advent of coherent technology, came unforeseen economical capacity growth on existing cables already well into their predicted operational life. This unexpected and competitive capacity potential initiated the tantalizing prospect of not only continual upgrades, but also of extending the economic, technical and operational life of systems beyond initial design intentions.
This “Extending the Life of Submarine Cable Systems – Addressing Issues and Challenges” workshop will take place on Thursday 21 April morning, between 09:00 and 10:00.
SubOptic 2016 Conference Oral Presentations
Xtera will present the following peer-reviewed/selected papers during SubOptic 2016 conference:
Ultra-Long Haul Unrepeatered Systems – At 13:00 on Tuesday 19 April 2016, Do-il Chang (Principal Engineer & Manager of Unrepeatered Systems) will report on the longest 100G unrepeatered transmission without any in-line active elements. The unrepeatered transmission is achieved by using a commercial distributed Raman system with coherent 100G transceivers (PM-QPSK) and ultra-low loss fiber with large effective area to support handling of high optical power levels. An enhanced ROPA configuration which utilizes additional pumping fibers is used to extend reach. A single 100G channel is transmitted over a record 626.8 km distance with a span loss in excess of 100 dB.
This paper is entitled “Ultra-Low Loss Fiber and Advanced Raman Amplification Deliver Record Unrepeatered 100G Transmission” and will be presented in the “Unrepeatered Applications” session (Paper TU2A – 1).
Different Options for Cable Redeployment – At noon on Wednesday 20 April 2016, Alan Proudfoot (Systems Engineer) will talk about cable redeployment. Re-configuration of an existing system (cable and/or repeaters) has been done in different ways to date, either performing this operation on a cable laying vessel, or by taking the recovered cable system, to a suitable depot for reconfiguration on land. The former may save time (particularly where the recovered span lengths can be used in the new application as this minimizes any cable transfers between tanks) but requires a cable ship with sufficient cable storage capacity and jointing resources, whereas the latter needs more transits and loading to the lay vessel. On the other hand this approach offers more flexibility in handling, adjustment of cable lengths/types and subsequent system testing. Alan will discuss practical aspects and advantages of these methods, and also consider hybrid and alternative approaches.
This paper is entitled “Fundamentals of Cable Redeployment” and will be presented in the “Managing System Lifetime” session (Paper WE1A – 3).
On the top of the two papers above, Xtera co-authored additional papers that will be presented in oral sessions:
Paper TU3A – 5: Application and Benefits of Raman-Enhanced Amplification Schemes in Tomorrow’s Optical Submarine Systems, to be presented by Colja Schubert (FhG-HHI) at 16:45 on Tuesday 19 April 2016.
Paper WE1A – 1: Applying the Hugo Upgrade Model to re-Deployed Systems, to be presented by Phil Lancaster (Vodafone) at 11:30 on Wednesday 20 April 2016.
