METHOD FOR FABRICATING AN OPTICAL FIBER CABLE HAVING IMPROVED POLARIZATION MODE DISPERSION (PMD) PERFORMANCE

摘要

Improved PMD performance is achieved in fiber optic cable fabricated in accordance with the principles of the invention by twisting each of a plurality of optical fibers in a controlled manner as the cable is being foamed. A controlled amount of twist is imparted to each optical fiber uniformly along its entire length. Uniformity of twist reduces twist-induced strain and promotes optimum PMD reduction.
