POLARIZATION MODE DISPERSION IN SPUN FIBERS WITH DIFFERENT LINEAR BIREFRINGENCE AND SPINNING PARAMETERS

This paper shows how the initial linear birefringence determines the n ecessary spinning parameters to produce spun fiber with optimum differ ential group delay (DGD) and polarization mode dispersion (PMD) proper ties. DGD measurements are reported on two pairs of fibers, each pair having been fabricated from a particular fiber preform. The fiber pair s each consist of a sample of spun and unspun fiber, These measurement s are then compared with theoretical simulations for each fiber to det ermine the required range of spinning parameters for a given initial l inear birefringence, These results should help in optimizing the spinn ing parameters for producing high-performance spun fibers.
