� The features of the fiber cable is a relevant aspect in relation to the global performance of fiber optic patch cords.

� To prevent that influence, most of the previously presented tests were performed on secondary coated fiber.

� The features of the materials used for their sheath layers (mainly extensional & retraction properties) are of capital importance.

� The level of fiber’s micro movement permitted in the cable might prejudice good behaviors of the whole assembly

•Diamond has already several solution for a good matching between connector and fiber/fiber cable. Pretreating of the cable, expansion chambers in the connector•Only a good collaboration between the connector manufacturer, the cable manufacturer, the user and the termination facility guaranties good results & performances.
