Storage holders for optical fibers

A storage holder for optical fibers comprising a base and a lid movable for opening or closing an access side to a storage chamber provided within the base for storing the fibers in the form of at least one winding with a minimum bend radius to the winding, and having an inlet and an outlet to the chamber for fibers, and the base and lid having cooperable means to ensure that the at least one winding remains within the storage chamber with the holder closed and remains within the storage chamber with the holder open until manually removed from within the chamber the cooperable means comprising spaced winding retaining means provided by the base, the winding retaining means extending across the access side to the chamber to retain the winding within the chamber, and the winding retaining means providing a winding insertion and removal gap for lateral insertion into and removal of the winding from the chamber, and the cooperable means also comprising at least one rib provided by the lid, the rib extending to a position adjacent to each retaining means to prevent fiber in the winding from entering laterally into the removal gap.
