Polarization Maintaining Optical Components: The Importance Of High-Grade Connectors

In a polarization maintaining (PM) fiber system the quality of a connection plays a crucial role. In order to offer the best overall perfromance, PM fibers must be properly oriented inside the connectors and the alignment features on these must guarantee an appropriate orientation across the mating adapter. Due to different mechanical constructions, not all fibre connectors and mating adapters are suitable for PM applications. The orientation procedures of high-quality PM fibre connectors and the evaluation of their polarisation performance are reviewed according to the current international standards.
