    Abstract: The present disclosure relates to a cable sealing device (30) for providing a seal around a communications cable (88, 90). The cable sealing device (30) includes a cable seal arrangement (38) positioned between first and second compression plates (92F, 92R). The cable sealing device (30) also includes an actuator (36) for compressing the first and second compression plates (92F, 92R) together to deform the cable sealing arrangement (38) such that the cable sealing arrangement (38) is adapted to form a seal about a cable (88, 90) routed through the cable sealing device (30). The actuator includes a cam lever (94) pivotally movable between an actuated position (P2) and a non-actuated position (P1). The actuator also includes a spring (98) for transferring load between the cam lever (94) and the first and second compression plates (92F, 92R). The spring (98) is pre-loaded when the cam lever (94) is in the non-actuated position (P1) (FIG. 13) with a pre-load equal to at least 50 percent of a total load applied through the spring (98) when the cam lever 94) is in the actuated position (P2).

    Abstract: An optical sensor (100) comprises: a holding sleeve (11); a fixed ferrule (12) fixedly mounted in said holding sleeve (11); a movable ferrule (13) movably mounted in said holding sleeve (11), a predetermined distance existing between a first movable end of said movable ferrule (13) and a first fixed end of said fixed ferrule (12) in said holding sleeve (11); a reflection part (14) arranged at a second movable end of said movable ferrule (13) opposite to said first movable end, for reflecting light entering the movable ferrule (13); and an actuation part (15), said actuation part (15) being constructed to drive said movable ferrule (13) to move so that said first movable end moves towards said first fixed end. An optical sensor assembly and a monitoring device comprising the optical sensor (100), or another sensor (1012) can remotely detect a mechanical movement in a passive mode. A first reflector (14, 1016) is configured to provide a first reflected optical signal. The sensor (100, 1012) is connected to the first reflector and has a first position and a second position, the second position configured to attenuate the first reflected optical signal more than the first position. The sensor is configured to move between the first and second positions in response to a monitored parameter (1018).

    Abstract: An optical fiber distribution element (1810) includes a chassis (1820), an optical device (1900) mounted to the chassis (1820), the optical device (1900) including a plurality of cables (2134) extending from the optical device (1900) into the chassis (1820), and a cable management device (2110/2210) mounted to the chassis (1820). The cable management device (2110/2210) includes a plurality of radius limiters in the form of spools (2132/2232) in a stacked arrangement for managing the cables (2134) extending from the optical device (1900) for further connection within the chassis (1820), wherein a first of the spools (2132/2232) defines a spool wall (2136/2236) having a different wall length than that of a second of the spools (2132/2232), wherein a first of the plurality of cables (2134) is routed around the first of the spools (2132/2232) and a second of the plurality of cables (2134) is routed around the second of the spools (2132/2232) that has a different spool wall length than that of the first of the spools (2132/2232).
