Title :
Suppression of Raman-induced pilot tone crosstalk using optical allpass filters
Author_Institution :

Abstract :
We propose a new type of optical allpass filter useful for mitigation of Raman-induced crosstalk among pilot tones and similar low-frequency labels. Crosstalk rejection was characterized in a 40-wavelength lab test system, and shown to agree well with theory.
