Managing Polarization Mode Dispersion

Facebook X LinkedIn Email
Michel W. Chbat

The increasing demand for bandwidth is driving most telecommunications operators toward the deployment of large-capacity transmission systems. Systems based on 10-Gb/s channel rates are being deployed, and suppliers have announced plans for channel rates as high as 40 Gb/s. Polarization mode dispersion represents a major impairment for high- bit-rate systems, producing pulse broadening and distortion, thus leading to performance degradation. Polarization mode dispersion in optical fiber stems from the breakup of circular symmetry in the core and cladding. Ideally, this symmetry renders...Read full article
