摘要： The present disclosure discloses a telecommunications enclosure (1) and a method for coupling a cable to a cable port of the telecommunications enclosure. The latter comprises a casing (10), a base (20) adapted to be removably coupled to the casing (10), and a plurality of sealing assemblies (40) adapted to be removably coupled to the base (20). Each sealing assembly (40) comprises an elastically deformable sealing module (43) interposed between a first member (46) and a second member (58). The first member (46) and second member (58) comprise each a main portion (47, 59) and a movable portion (51, 63), wherein the movable portion (51, 63) is movable between an open position, wherein a cable is allowed to access to the elastically deformable sealing module (43), and a closed position; the elastically deformable sealing module (43) has an access (44) to allow the cable to enter the respective cable port (42) when the movable portions (51, 63) are in the open position. In the closed position, the movable portions (51, 63) are coupled to the respective main portion so as to wrap the cable. The elastically deformable sealing module (43) is held by the main portions (47, 59) while the movable portions (51, 63) are in the open position.

摘要： An electrical cable for vertical applications includes a core having a length L, a sheath surrounding the core and extending through the whole length L and a reinforcing jacket surrounding the sheath and in direct contact therewith. The reinforcing jacket is made of concentric layers including a first layer longitudinally extending from a first cable end (the proximal or upper cable end, in use) towards a second cable end (the distal or lower cable end, in use) substantially along the whole length L. The reinforcing jacket also includes at least one further layer longitudinally extending from the first cable end towards the second cable end for a length shorter than L. At least one layer of the reinforcing jacket is a circumferentially closed metal tube.

摘要： An optical-fiber ribbon includes optical fibers (e.g., reduced-diameter optical fibers) arranged in parallel within optical-fiber units, wherein at least one adjacent pair of optical-fiber units is separated by a longitudinal adhesive-free spacing for a portion of the optical-fiber ribbon's length. Typically, each adjacent pair of optical-fiber units is separated by an adhesive-free spacing for a respective portion of the optical-fiber assembly's longitudinal length. In an exemplary embodiment, longitudinal adhesive-free spacings effectively increase the width of an optical-fiber ribbon formed of reduced-diameter optical fibers so that the optical-fiber ribbon achieves a more conventional optical-fiber ribbon width, thereby facilitating mass-fusion splicing using standard splicing equipment.
