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...
PDL and PMD Emulation with Control of Amplitude and Spectral Dependence to a Sub-Channel Level across the C-Band
Optical instruments Optical communications
2011/5/25
We present results of a polarization diverse LCoS wavelength processor. Applications include impairment simulation of broadband, channelized and intra-band PMD and PDL for detailed experimental sensit...
New PMD-Induced Crosstalk in the Presence of PDL in a Polarization-Multiplexed Ultrahigh-Speed Transmission
PMD-Induced Polarization-Multiplexed Ultrahigh-Speed Transmission
2011/5/15
New impairments in polarization-multiplexed ultrahigh-speed transmission in the presence of PMD and PDL are identified analytically and experimentally. Crosstalk is inevitable even with PSP launching,...
PMD and PDL Behavior of Aerial Fiber with the Accelerated Jones-Matrix Eigenanalysis
Fibers characterization Fiber measurements
2010/6/10
Polarization characteristics of aerial SMF were examined with the accelerated Jones-Matrix Eigenanalysis, comparing to interferometric method. PMD shows strong correlation with environmental changes b...
PDL Mitigation in PolMux OFDM Systems using Golden and Silver Polarization-Time Codes
Fiber optics communications Optical communications Modulation
2010/6/4
Polarization-Time coding can highly mitigate PDL impairments in optical OFDM sys-tems. The performances of two full-rate Polarization-Time codes, the Golden and Silver codes, have been evaluated showi...
We investigate the effect of polarisation dependent loss (PDL) in wavelength division multiplexing-passive optical network (WDM-PON) with injection seeded reflective semiconductor optical amplifier (R...
Realtime 40 krad/s Polarization Tracking with 6 dB PDL in Digital Synchronous Polarization-Multiplexed QPSK Receiver
PDL Digital Synchronous Polarization-Multiplexed QPSK Receiver
2008/8/3
Fast polarization changes of 40 krad/s (and 6 dB PDL) are tracked in a 2.8 Gb/s realtime coherent QPSK receiver with 0.7 dB (2.4 dB) sensitivity degradation.
PMD and PDL Tolerance of Polarization Division Multiplexed Signals with Direct Detection
PMD PDL Tolerance Polarization Division Multiplexed Signals Direct Detection
2008/8/3
The PMD tolerance of a polarization-division-multiplexed signal with direct detection depends on the signal bandwidth and time alignment between channels, and PDL impairments are affected by the polar...
Experimental Demonstration of the Reduction of PDL and DGD in Fibre Bragg Gratings by Using a Twisted-Fibre for the Inscription
PDL DGD Fibre Bragg Gratings Twisted-Fibre Inscription
2008/8/3
We experimentally report the possibility to reduce PDL and DGD in fibre Bragg gratings by inducing polarization mode coupling. This is obtained by using a twisted-fibre for the inscription.
