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...
Investigation of DGD and Delay-Line Interferometer Phase Tolerance of Integrated Receiver Module for 86 Gb/s NRZ-DQPSK modulation
DGD Delay-Line Interferometer Phase Tolerance Integrated Receiver Module NRZ-DQPSK modulation
2015/7/20
We investigate the performance of a free-space DLI integrated receiver for 43 Gbaud/s NRZ-DQPSK.The DGD tolerance (1dB penalty) is quantified at 47% of the baudrate, and the DLI phase tolerance (1dB p...

We demonstrate highly stable field transmission of 160-Gb/s signal utilizing adaptive PMD compensator, which employing variable DGD generator with ultra high time-resolution of 0.053 fs.
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
2015/8/3
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.
DGD Estimation from FIR Filter Taps in Presence of Higher Order PMD
DGD Estimation FIR Filter Taps Higher Order PMD
2015/7/31
We estimate the DGD τ ( ω ) over the complete system bandwidth from FIR filter taps in coherent receivers with digital equalization, obtaining accurate DGD values even in presence of higher order PMD...
