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...
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...
Demonstration of Simultaneous OSNR and CD Monitoring using Asynchronous Delay Tap Sampling on an 800 km WDM Test Bed
Simultaneous OSNR CD Monitoring Asynchronous Delay Tap Sampling WDM Test Bed
2015/7/20
We demonstrate simultaneous monitoring of OSNR and CD using asynchronous delay-tap sampling on a commercial WDM system. Accuracies of 0.5 dB for OSNR and 30 ps/nm for CD was obtained in the presence o...
Bit Rate Identification Using Asynchronous Delay-tap Sampling
Bit Rate Identification Asynchronous Delay-tap
2015/7/31
We demonstrate a method for determining the bit rate with an accuracy of better than 0.5% based upon second-order autocorrelation and asynchronous delay-tap sampling for NRZ, NRZ-DPSK and RZ formats.
