SC429 - Advances in Flexible Photonic Networks and Open Architectures

Monday, 04 March
13:30 - 16:30

Short Course Level: Beginner


David Boertjes; Ciena, Canada

Short Course Description:

Have you ever wondered what CD, CDC, Flexible Grid, and Elastic Networks really mean to network operators?  The emerging landscape can be overwhelming.  This course will explore the types of flexible photonic networks which are being deployed today and will highlight the pros and cons of various technology choices to help students better navigate the multitude of options.

The first part of this course will focus on the network design and functionality beginning with ROADM types and Add/Drop options.  We will also explore the technologies that are aimed at scalability and ease of deployment.

The second part will explain the shift toward performance-centric network design which has seen an explosion in the use of Raman amplification and optical instrumentation which is driving to high capacity and high spectral efficiency in all network segments today.  We will explore the role of various contributors to the noise in the system which is the limiting factor for capacity and how flexible grid is driving to a lower cost per bit.

Finally, these technology trends will be taken together with SDN automation to show the benefit of elastic optical networks in specific use cases that include Capacity Mining and Network Defragmentation.

Short Course Benefits:

This course will identify progress and challenges in the following areas:

  • Identify the best technologies to meet various network needs, e.g. CD vs. CDC

  • Understand the design goals which maximize capacity and minimize cost

  • Understand the value trending technologies like Raman, OTDR and C&L and how they impact the long-term value of the photonic layer

  • Realize the tradeoff of noise and capacity in a real network application

  • Understand the benefits of Flexible Grid and how it is operationalized in real networks today

  • Articulate the use cases of elastic networking including Capacity Mining and Network Defragmentation

Short Course Audience:

This course is intended for individuals with a working knowledge of ROADM networks and coherent modems. It will be of value for industrial professionals (system designers, managers) who need to understand the tradeoffs of performance and capacity in the design and deployment of optical networks, as well as for researchers who are new to the field.
