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.

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.

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.

A shuttered adapter for a communications connector is formed of two pieces in the form of a retainer and a door. The retainer is formed of plastic and includes facing resilient lips for snap-on attachment to a connector body. A resilient tab and a first hinge portion are integrally formed as features of the retainer during an initial molding process of the retainer. The door is formed of plastic and includes a second hinge portion integrally formed therewith during an initial molding process of the door. The second hinge portion is attached to the first hinge portion to permit the door to pivot relative to the retainer. The resilient tab contacts a top of the door to urge the door into a position covering an opening in the connector for receiving a mating connector.

A communication patching system includes a platform configured to support a plurality of cables and a first panel pivotably mounted to the platform, the first panel having at least one holder for securing communications adapters to the first panel. A first set of communications adapters is connected to the platform, and a second set of communications adapters mounted in the at least one holder. The first panel is pivotable between a first position in which the second set of communications adapters is spaced from the first set of communications adapters by a first distance and a second position in which the second set of communications adapters is spaced from the first set of communications adapters by a second distance greater than the first distance.

摘要:
A connectorized fiber optic cabling assembly includes a loose tube fiber optic cable and a connector assembly. The cable has a termination end and includes: an optical fiber bundle including a plurality of optical fibers; at least one strength member; and a jacket surrounding the optical fiber bundle and the at least one strength member. The connector assembly includes a rigid portion and defines a fiber passage. The connector assembly is mounted on the termination end of the cable such that the optical fiber bundle extends through at least a portion of the fiber passage. The plurality of optical fibers of the optical fiber bundle have a ribbonized configuration in the rigid portion of the connector assembly and a loose, non-ribbonized configuration outside the rigid portion. The plurality of optical fibers undergo a transition from the ribbonized configuration to the loose, non-ribbonized configuration in the rigid portion of the connector assembly. According to some embodiments, the rigid portion of the connector assembly includes a rigid connector housing.
