Title:
MONITORING OPTICAL DISPERSION BASED ON VESTIGIAL SIDE BAND OPTICAL FILTERING
Document Type and Number:
WIPO Patent Application WO2003007509
Kind Code:
A3
Abstract:
Techniques for monitoring frequency-dependent parameter and optical property such as optical dispersion in a modulated optical signal with sidebands based on optical vestigial sideband (VSB) filtering. Monitoring implementations for both chromatic dispersion and polarization-mode dispersion (PMD) (1000) are described as examples.
