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. Understanding of the physical mechanism allows the realization of same and better performance improvement as in the previous work (Wiesnfeld et. al., 2005) with only 2, optimally positioned filters
