pp: 842-846Single-end Measurement of Polarization Mode Dispersion in Optical Fibers with Polarization-dependent LossHui Dong and Ping Shum doi:10.2529/PIERS061005224120 Downloads: 957 Abstract:A new reflectometric technique is proposed to measure the polarization mode dispersion (PMD) in optical fiber links with polarization-dependent loss. Based on the PMD dynamical equation, some important relations can be obtained to make the backreflection measurement of PMD possible. Thus we can perform the single-end spectral resolved measurement of the differential group delay and the differential attenuation slope in both frequency and time domains simultaneously. In principle, this technique can be realized using continue-wave or pulsed probe lights and based on far-end Fresnel reflection or distributed Rayleigh backscattering. Some experimental results confirm the validity of the proposed method.References:1. Corsi, F., A. Galtarossa, L. Palmieri, M. Schiano, and T.
