Second-Order PMD Monitoring from Adaptive FIR-Filter Tap Coefficients in a Digital Coherent Receiver
Fiber optic communication Coherent communications Homodyning
2011/5/26
We propose a straightforward algorithm to estimate second-order PMD from adaptive FIR-filter tap coefficients in a digital coherent optical receiver. The novel algorithm is verified with 100-Gbit/s du...
Monitoring of Orthogonal Polarization Power Ratio due to PDL using Intensity Tones in Polarization Multiplexed Signals
Fiber optics communications Fiber optics links subsystems
2011/5/25
We demonstrate a technique for monitoring orthogonal polarization power ratio (OPPR) occurring in WDM polarization-multiplexed signals due to PDL. We employ low-frequency intensity tones to estimate t...
Remotely Pumped WDM-PONs for Bidirectional 10-Gb/s Transmission with Channel Fault Monitoring
Fiber optics communications Fiber optics amplifiers oscillators
2011/5/22
WDM-PONs for 10-Gb/s bidirectional transmission are realized with REAMs as ONUs and ASE source for channel fault monitoring. The remotely pumped scheme can simultaneously boost up- and down-stream sig...
OSNR Monitoring Using Two Fiber Interferometers
Fiber optics communications Phase modulation
2010/6/10
In-band OSNR from 5 to 30dB of a single 10G NRZ-OOK channel was measured by two fiber interferometers within an accuracy of ±0.5dB without requirement for knowledge of the noise-free extinction ratio ...
In-service Monitoring of PMD Induced Optical Signal Degradation Using SOP Vector Trajectory on the Poincare Sphere for High-Speed Reconfigurable Optical Networks
PMD Induced Optical Signal Degradation SOP Vector Trajectory Poincare Sphere High-Speed Reconfigurable Optical Networks
2009/7/20
We studied an in-service signal quality estimation method by using wavelength resolved SOP vector trajectories on Poincare Sphere and successfully distinguished PMD induced signal degradation with suf...
