Measurement of Mean Fiber DGD Using Asynchronous Delay-Tap Sampling
Fiber measurements Fiber optics communications
2015/6/10
We demonstrate measurement of mean fiber DGD using asynchronous delay-tap sampling in a 10Gbit/s WDM test-bed. With and without polarization scrambling, mean DGD values of 30.5ps and 26.2ps were measu...
Wide Dynamic Range OSNR Monitoring for RZ-DQPSK Systems using Delay-Tap Sampling Technique
Fiber optics communications Fiber optics links subsystems
2015/6/5
We propose half-symbol delay-tap sampling for OSNR monitoring and extend the monitoring range to 5−45 dB. The proposed method also enables calibration-free monitoring with range of 16−43 d...
Experimental Comparison of Performance Monitoring Using Neural Networks Trained with Parameters Derived from Delay-Tap Plots and Eye Diagrams
Fiber optics communications Pattern recognition neural networks
2015/6/4
We experimentally demonstrate the use of artificial neural networks trained with parameters derived from both delay-tap plots and eye diagrams for multi-impairment monitoring in a 40-Gbit/s non-return...
OSNR Monitoring Technique for PDM-QPSK Signals Based on Asynchronous Delay-Tap Sampling Technique
Fiber optics communications Fiber optics links subsystems
2015/6/4
We propose and demonstrate a new technique for monitoring the individual OSNR of each polarization tributary of PDM-QPSK signals. The results show that the performance of this technique is not sensiti...
