Optical fiber links made by concatenating unidirectionally spun fibers with alternate helicities are considered. The polarization mode dispersion of such links is thoroughly analyzed, and it is shown that with a proper design of the link, substantial differential group delay (DGD) reduction can be achieved. In particular, the highest performance is attained when a well-defined balance condition is satisfied. By relaxing this condition, a tradeoff between the complexity of the link structure and the DGD reduction can be achieved as well.
