Hosted By: Optical Communications Technical Group

Eastern Time (US & Canada) (UTC - 05:00)

Optical fibers have supported the drive for ever-increasing data consumption. At every stage, the requirements on total system throughput and cost must be considered and balanced. As most data is sent over optical fibers, spatial division multiplexing (SDM) is an effective candidate for improving the per-fiber capacity.

SDM is especially effective when used in applications that are constrained in terms of power or space. SDM comes in many forms from laying more fibers, adding multiple cores, or using multiple modes, each of which has its own advantages and disadvantages. Specifically, multicore optical fiber (MCF) presents a simple route to upgrade the throughput of transmission systems, as if the fiber is designed and manufactured appropriately can act as a simple independent optical path, to a coupled signal that requires specialty processing.

In this webinar hosted by the Optical Communications Technical Group, Daniel Elson will go through a technology that enables MCFs for use as a transmission medium. As a further to this, Dr. Elson will present the droop model which can be used to predict performance simple uncoupled MCFs in long-haul transmission systems. And then demonstrate how MCF can improve the total throughput in power-constrained optical systems link subsea cables.

What You Will Learn:
• About multicore fibers and their characteristic key metrics
• Using multicore fiber for optical fiber transmission, an under-utilized technology from spatial division multiplexing
• How multicore fibers can be used for long-haul transmission to improve system throughput

Who Should Attend:
• Students
• Postgraduates
• PhD students

About the Presenter: Daniel J. Elson from KDDI Research Inc.

Daniel Elson studied for an undergratuate masters in physics at Imperial College London and then completed his PhD in optical communications at UCL (University College London) under Prof. Polina Bayvel. His thesis focused on improving transmission rates in optical fibre communication systems considering the nonlinear Kerr effect. An internship at Japan's national institute for communication technology (NICT) started his research in spatial division multiplexing (SDM), specifically multicore fibres. He then moved to KDDI Research Inc. where he continued his research into SDM technologies.
