A splice closure and fibre organiser device (10) comprises a substantially elongate body 5 member (12), closure member (16) and a foldable organiser tray (14) for accommodating at least one fibre splice and/or length(s) of excess fibre. The organiser tray which includes a plurality of fold lines (21) provided by respective living hinges is capable of being wrapped around part of the bodymember, into a generally cylindrical or part cylindrical shape, to close or partially close the closure. The fold lines enable the organiser tray to be folded into an extra 10 dimension, from a flat planar structure into a generally cylindrical or part cylindrical shape. This enables the closure to be more compact without compromising the bend control radius characteristics of the organiser tray. By restricting the minimum bend radius of the organiser to that of the fibre to be used bend control of installed fibre can be readily achieved. The device is particularly suitable for use in FTTX applications.

An organizer for an optical fiber cable has at least two loop retaining sections (16; 33) facing each other with a predetermined distance such that a loop (10) of the optical fiber cable (12) is restrained between the loop retaining sections (16; 33) by an elastic resetting force of the looped optical fiber cable (10). Certain types of organizers are removably mounted to a base to be free-standing.

The invention relates to a holding fixture (71) for holding at least one cable (72) with an affixing member (1) and a clamping member (40). In order to ensure that the clamping member (40) and the affixing member (1) are arranged in a holding position (H), in which the cable (72) is securely held, the invention provides that the holding fixture (71) is provided with an indicator element (77, 78) that is at least sectionwise laterally shielded by the clamping member (40), if the clamping member (40) is arranged before its holding position (H), and that is arranged in an indication position (I), in which it can easily be perceived, if the clamping member (40) is arranged in its holding position (H).

A locking system for an enclosure (10) wherein the enclosure (10) includes a base (12) and a moveable cover (14). The cover (14) is moveable only when a key operated slide (70) is moved by a key (26) inserted into a key slot (24). Once the cover (14) is moved, the key (26) cannot be removed from the key slot (24) until the cover (14) is returned to the closed positioned. A moveable latch (50) holds the cover (14) to the base (12). The key operated slide (70) selectively connects and disconnects from the latch (50) to allow the cover (14) to be moved. The latch (50) cooperates with a clip (94) on the slide (70) which allows the slide (70) to return to the locked position to allow the key (26) to be removed from the key slot (24) only when the cover (14) and the latch (50) are closed. One or two latches can be provided with a corresponding number of key operated slides (70). The key (26) is rotatable to move the slide (70) from an extended and locked position to a retracted and unlocked position.

The present invention relates to a cable sealing and retaining device capable of sealingly guiding and retaining a cable through an opening of the cable sealing and retaining device. The present invention provides an improved cable sealing and retaining device which allows a simple releasable fixation of a cable to the cable sealing and retaining device while the cable is sealingly guided through an opening provided with the cable sealing and retaining device. The cable sealing and retaining device (40; 60) comprises a sealing part (11) providing a passageway with an inner seal (14) through which a cable (2) is sealingly guidable, and an outer seal (15) arranged on an outer circumference of the sealing part (11). The cable sealing and retaining device (40; 60) comprises a fixation part (12) for retaining the sealing part (11) in longitudinal direction of the passageway; and a sleeve portion (47; 67) forming an opening (41; 61) for receiving the fixation part (12) and the sealing part (11) of the cable sealing and retaining device (40; 60). The sleeve portion (47; 67) provides a sealing section (42; 62) for co-operating with the outer seal (15) to perform a sealing therebetween. the cable sealing and retaining device (40; 60) is characterized by the fixation part (12) which provides fixation means (24) on its outer circumferential surface to fix the fixation part (12) to the sleeve portion (47; 67).

The present invention relates to a positioning means for a fibre optic connector assembly, a fibre optic connector assembly and a fibre termination unit comprising the positioning means through which manufacturing tolerances can be absorbed to provide an improved optical interconnection with a high signal transmission rate. The positioning means (1) comprises a receiving means (5) for receiving one of a jack assembly or plug assembly (2) and a stationary support (6) supporting said receiving means (5), wherein the receiving means (5) is displaceable to a certain extent relative to the stationary support (6) at least along one direction other than a connection direction for optically interconnecting the optical fibers allowing an alignment of the receivable jack or plug assembly (2) along the direction transversal to the connection direction. A spring loaded element (8) resiliently urges said receiving means (5) away from the support (6) in one embodiment.
