ULH Systems with Strong Filters acting as Amplitude Regenerators

Not Accessible

Your library or personal account may give you access

Abstract

It is shown that strong optical filters that are included in a ULH system can suppress, or enhance amplitude noise depending on their positioning. Our study explains the improvement measured in a 60-span system with 10 band-limited DGEs [1]. Understanding of the physical mechanism allows the realization of same and better performance improvement as in [1] with only 2, optimally positioned filters.
