DWDM in Access Networks

On-Demand Recording

Watch the recording of this fiber Webinar, part of the Command the Network VIAVI Spring/Summer 2020 educational webinar series.

Whether it’s for new commercial services, 5G Xhaul or a Distributed Access Architecture (DAA) in support of Remote Phy (RPHY), the demand for bandwidth is driving service providers to invest in their fiber networks. As fiber pushes deeper and deeper into the network, technologies that were primarily used in the Core and Metro are now also migrating to the Access. Dense Wave Division Multiplexing (DWDM) is one of those technologies originating in the core in the early 2000’s, then migrating to the Metro about a decade later and now entering the Access Network. It provides a way to add multiple virtual lanes to an existing fiber thus increasing the amount of data that can be transmitted over it as well as wavelength routing for distribution.

While DWDM provides a cost-effective, scalable solution for delivering services, the procedures and test equipment are very different than other fiber-based technologies.

In this session we provided an overview of DWDM, and discussed the various stages of deployment and test solutions to ensure success.

Highlights included:

  • Review of DWDM and its components
  • Implementing the best practices for installing and maintaining DWDM networks
  • How to overcome common testing challenges associated with DWDM networks
  • Understand the testing tools required for DWDM installation and maintenance
