SC447 - The Life Cycle of an Optical Network: From Planning to Decommissioning
Sunday, 11 March
09:00 - 12:00
Short Course Level: Beginner
Instructor: Andrew Lord; BT Labs, BT, UK
Short Course Description:
This course walks the delegates through an entire optical network life cycle from an operator’s point of view, from the initial requirements, vendor selection, network design and planning, installation and provisioning, operation and management and final use as a legacy technology before retiring the network. Frequent referral is made to actual network scenarios. The course will cover a large number of network related questions, without going into unnecessary depth. These will include overall network design including layers above the optical layer, questions around network flexibility, resilience and reliability. It will also examine physical layer questions of power budgets, margins, ageing and practical installation issues. Operational issues look at different approaches to adding capacity, handling potential technology upgrades within the lifecycle of the network, network monitoring and handling of network failures and fiber breaks. Whilst not excluding older technology solutions, the course will focus on high speed coherent-based optical core networks and the different challenges arising on the metro side. Practical aspects will be considered including power and space requirements in exchange buildings. Looking into the future, the course will consider to what extent flexibility in the optical layer is important in areas such as flexgrid, optical superchannels, bit-rate variable transponders and levels of flexibility within the ROADM node. Also included will be an introduction to the capabilities of more automated management solutions such as SDN. Finally the course will assess the overall cycle in terms of technology cost-effectiveness and life-time.
Short Course Benefits:
This course will enable you to:
Identify key activities comprising whole-life optical network procurement, design, operation and management
Sense the broad time scale for an optical network including reasons for building it and factors affecting how long it should be in operation.
Appreciate different types of optical network and the range of network operator requirements. Deduce the implications for the solution design.
Review the range of optical network technologies available to build networks, covering legacy through to future roadmap options.
Understand the need for appropriate resilience and reliability across the network, from devices, sub-systems, network equipment and overall network operation
Explore how unpredictable future traffic drives the need for both network flexibility and capacity growth and appreciate that the scope for both flexibility and growth imply increased network cost
Appreciate the impact of the quality of the available optical fibre infrastructure on the phsyical layer system design, including margin allowance.
Grasp the impact on future networks of new technologies, including flexible transceivers and ROADMs, and finer resolution wavelength grid and a more open contol anad management based around Software Defined Networking (SDN)
Short Course Audience:
This advanced-beginner course is intended for a diverse audience – in fact anyone wanting a broad operator-based perspective on the optical network journey. No in-depth knowledge will be required – the objective is sufficient breadth that anyone will be able to see where their field of expertise fits into the overall picture. This is a brand new course for 2017 with entirely new material, much of which is derived from real network deployment experience.
Andrew Lord joined BT in 1985 after a BA in Physics from Oxford University, UK. He has been involved in the procurement, design, installation and operation of most of BT’s optical networks over the past 25 years. Since 2012 he has led BT’s optical network research including SDN. He is a regular speaker at international conferences, has published over 100 research papers and is General Chair for OFC 2017.
