What Is Dispersion and How Does It Impact the Network?

High speed networks (100G+) NEMs and lab
  • August 13, 2015

Ng Chin Keong

Applications Engineer, EXFO

CK has experience working in the area of Mobile Front Haul and Optical Transport Networks.

He's been with EXFO for about 2 years. Prior to that he was a Global Service Engineer specialized in DWDM network integration at the Ericsson China and Malaysia.

He also worked as a Project Manager in the Bangkok for True Move, Thailand. 

Exclusive webinar series on high speed networks/DWDM

EXFO is proud to present its webinar series on high speed networks, 40G/100G, and dense wavelength-division multiplexing (DWDM) technology. This webinar series will discuss the best practices for deploying 100G/DWDM networks, as well as ensuring the success of the activation and maintenance phases, for optics and transport. It will also discuss the recommended tests in each stage of the network's life cycle.

Webinar1: What is dispersion and what is its impact on the network?

The first webinar in the high speed/DWDM series discusses the problem of dispersion and the impact it can have on the network. It explains the two types of dispersion (chromatic dispersion and polarization mode dispersion) and why they can cause network failures, the typical dispersion tests and the applicable standards and dispersion thresholds for several types of services.
