Abstract: A pre-terminated cable assembly includes: a fiber optic cable comprising a plurality of optical fibers surrounded by a polymeric jacket; the jacket including a transition region, wherein the plurality of optical fibers is broken out into fiber subunits on one side of the transition region; a sleeve fixed to the transition region; and a circumferentially compressing member mounted on the transition region of the jacket adjacent the fixing sleeve. In this configuration, the cable assembly can have sufficient strain relief and protection for the optical fibers as the cable is manipulated into place during installation.

Abstract: A cable gland holder includes a base member and a core for holding a plurality of cable glands. In one embodiment, a plate is removably attached to the core. In another embodiment, more than one plate is attached to the core. Each plate has a grooved edge presenting a series of grooves to which cable glands may be attached. The holder may be attached to a vertical or horizontal raceway of a network rack to assist in protecting and organizing the cables within the raceway.

Abstract: A removable cable gland includes a two-piece fitting which may be laterally assembled over a cable, as opposed to a cable being fed through an opening in the fitting. A two-piece compression nut may also be laterally assembled over the cable. The two pieces of the compression nut are slid together along a longitudinal direction of the cable by a tongue and groove arrangement. The two pieces of the fitting are plugged together in a direction perpendicular to the longitudinal direction of the cable. Once first threads of the fitting are engaged to second threads of the compression nut, the two-piece fitting is locked together by the surrounding compression nut. Simultaneously, the two-piece compression nut is locked together, such that the tongue may not slide longitudinally relative to the groove, due to the first and second thread engagement.

Abstract: An attenuator for optical signals includes a base. A first ferrule has a first optic fiber passing through a central bore therein and attached to a first lens at an end of the first ferrule. The first ferrule is fixed in position relative to the base. A second ferrule has a second optic fiber passing through a central bore therein and attached to a second lens at an end of the second ferrule. The second lens faces the first lens. The second ferrule is fixed to the base and can be moved relative to the base by a user adjustment feature, so that the second lens may be moved relative to the first lens. The relative placement between the first and second lens controls the attenuation of the attenuator.

Abstract: A fan-out unit for a data communication system includes: a plurality of optical fibers; and a faceplate with a plurality of ports arranged in at least one row, each of the ports being optically interconnected with a respective one of the optical fibers and configured to received a mating optical fiber. The faceplate includes a first visual indicia associated with the ports that indicates an arrangement in which mating optical fibers are to be inserted into the ports, the first visual indicia being easily readable when the faceplate is in either a first horizontal orientation or a first vertical orientation, but not being easily readable when the faceplate is in a second horizontal orientation that is inverted from the first horizontal orientation or a second vertical orientation that is inverted from the first vertical orientation.

Abstract: A fiber optic ribbon cable includes: a plurality of substantially parallel optical fibers formed into a ribbon, the ribbon extending in a longitudinal direction and having first and second ends; and a termination assembly attached at each of the first and second ends of the ribbon. Each of the termination assemblies includes a body and a ferrule, the body having a key on an upper surface thereof. The ferrule has a polished contact surface that exposes ends of the optical fibers; the contact surface forms an oblique angle relative to a plane normal to axes defined by the fibers. The termination assemblies at the first and second ends of the ribbon either both face slightly upwardly or both face slightly downwardly.
