Since the first installations of single-mode fiber in 1983, there have been many improvements on fiber attenuation, dispersion and system performance. Unfortunately the fibers with their original limitations are still being used with higher speed transmission and signal quality requirements. The good news is there are solutions which will require either level 1 (attenuation and reflectance) or level 2 fiber characterization (CD and PMD) to establish a baseline.

This session will allow the attendees to understand the current limitations of their legacy plant, the causes and solutions. It will provide guidance for future upgrades and how best to cost effectively address attenuation, dispersion and optical reflectance issues that affect system signal quality when implementing higher speed and dense wavelength division multiplexing technologies.
