Title:
二重偏波信号の周期的光フィルタリングによる光チャネル監視のための方法及びシステム
Document Type and Number:
Japanese Patent JP6658347
Kind Code:
B2
Abstract:
Methods and systems for optical channel monitoring of dual polarization optical signals may use a periodic optical filter to scan a free spectral range of the periodic optical filter. The optical signals may further be tone modulated using frequency or amplitude modulation. From a filtered signal, normalized Stokes vector signals may be generated using a polarimeter. The normalized Stokes vector signals may be digitally processed to identify center frequencies and power levels of individual optical subcarriers.
