Monitoring of Orthogonal Polarization Power Ratio due to PDL using Intensity Tones in Polarization Multiplexed Signals
Fiber optics communications Fiber optics links subsystems
2015/5/25
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...
Reduced Complexity Precoding Based Peak-to-Average Power Ratio Reduction Applied to Optical Direct-Detection OFDM
Complexity Precoding Power Ratio Optical Direct-Detection OFDM
