This letter describes the polarization mode dispersion (PMD) characteristic of optical fiber ribbons inserted tightly into helical slots. We investigate the mechanism of the birefringence induced in the optical fiber ribbons by lateral stress resulting from tension and bending in the helical slots. We discuss methods for the design of low PMD cables with reduced birefringence by considering coating materials and tensile strain control.
