Paper Abstract

Polarization mode dispersion (PMD) in telecommunication fibers is caused by their random birefringence and depends on temporary coherence of the light coupled into the fibers. This phenomenon resulting in light pulses broadening decreases bite rate in telecommunication lines and is expressed in terms of differential group delay (DGD). Measurement of the DGD can be used to estimate the value of PMD, and also for compensation of the PMD value. In this paper the results of PMD compensation by using the Faraday rotator and a longitudinally strained highly birefringent fiber are presented. By controlling simultaneously the longitudinal strain and the Faraday rotator current during DGD measurements almost total compensation of PMD for a 30-km-long telecommunication optical fiber has been achieved.
