Abstract: An apparatus is described for the storage of the fibers of glass-fiber cables (23) in distribution devices in a telecommunication network, such as, for example, in casings (9) of end distributors or distribution frames (10). In order to be able to store, in a break-safe and manipulatable manner a splice reserve, wound up as, for example, in a splice cassette (58) with a movable feed cable (21), at least one cassette box (1), is provided and which is designed to receive a cassette (20). The box (1) is stored in a casing (9, 10) of the distribution device, and is provided with a removal opening (7). The box (1) can be moved from an essentially vertical storage position in the casing (9, 10) to an essentially horizontal removal position with the removal opening (7) located at the top.
