Abstract:
A cable installation system (20) for use by a cable installer (21) may include a plurality of cable dispensers (22-24) having different lengths of cable. In particular, each cable dispenser (22-24) may also have a non-numeric, length-identifying marking associated therewith corresponding to the length of cable. Furthermore, the system may also include a cable dispenser indicator device (28, 28’, 28’’, 28’’’) for use by the installer (21) to determine a distance between first and second locations, such as a cable tap (29) and a subscriber interface (30). The cable dispenser indicator device (28, 28’, 28’’, 28’’’) may also provide an indication to the installer (21) of the non-numeric, length-identifying marking corresponding to the determined distance so that the cable installer (21) can select the corresponding cable dispenser (22-24) from the plurality thereof. By way of example, the non-numeric, length-identifying markings may include a series of different colors and/or graphics for respective length ranges.
Abstract:
A device for attaching a non-ruggedized fiber optic connector to a ruggedized fiber optic adapter port may include a converter, a sealing shell and a sealing element. The converter may include a first end including a first mechanical interface compatible with the ruggedized fiber optic adapter port, a second end including a second mechanical interface, and a channel for receiving the non-ruggedized fiber optic connector. The sealing shell may include a first end including a third mechanical interface compatible with the second mechanical interface of the converter and a second end supporting a cable seal for forming a seal with a cable extending from the non-ruggedized fiber optic connector. The sealing element may provide sealing between the first end of the sealing shell and the second end of the converter.
Abstract:
Flexible fingers for flexible printed circuits improve the crack resistance of prior art designs. The crack resistance can be improved by encapsulating the trace inside additional layers such that the outer two layers include only the lands of the through-hole, and all other copper is etched away. The crack resistance can also be improved with strategically adding copper on layers other than the trace layer including attaching is to the land of the through-hole as a stub. These two designs can be combined to include a stub trace into a four-layered design.
Abstract:
A cable management assembly is disclosed that can be completely factory assembled and shipped to a site for later mounting directly to a telecommunications rack or cabinet. The cable management assembly includes a plurality of cables secured within a carrier assembly. In one aspect, the cables have different or customized individual lengths. The carrier assembly can include a bracket portion and a plurality of cable management members extending from the bracket portion. The plurality of cable management members can define a plurality of cable routing apertures through which at least some of the plurality of cables extend. The bracket portion is mountable to a telecommunications rack with the plurality of cables mounted within the carrier assembly.
Abstract:
Trunk gland adapters include an adapter body having an internal bore that is sized to receive a trunk cable gland so that a front end of the trunk cable gland extends through a front opening of the internal bore and a plurality of attachment clips that are configured to releasably attach the adapter body to a mounting aperture in a wall of a fiber optic enclosure. Related trunk gland units and methods of routing a trunk cable into an enclosure are also disclosed.
Abstract:
Methods of identifying available connector ports on rack mounted equipment use an image capture device to capture an image of a front face of an equipment rack. The captured image is compared to at least one stored image. A patch cord insertion status of at least one connector port included on an item of equipment that is mounted on the equipment rack is then determined based at least in part on the comparison of the captured image to the at least one stored image.
Abstract:
An optical tap includes a support with a first port facing a first ferrule supporting a first fiber along a first axis. A beamsplitter is connected to the support and intersected by the first axis. A second port is fastened to the support and facing a second ferrule supporting a second fiber along a second axis that intersects the beamsplitter. A third port is fastened to the support and facing a third ferrule supporting a third fiber along a third axis that intersects the beamsplitter, wherein the beamsplitter splits a first light signal from the first port to sends first and second portions of the first signal to the second and third ports, respectively. When the beamsplitter may optionally be configured as a polarizing element and include elements configured to rotate relative to each other to change a ratio of the first and second portions. The optical tap may optionally include a light intensity controlling device located in an optical path between the beamsplitter and at least one of the second or third ferrules. Optionally, a first collimating lens is configured to expand a first light beam that is substantially aligned with the first axis, and a second collimating lens is located between the beamsplitter and the second port, and configured to contract the second portion of the expanded first light beam to the second port.
Abstract:
A lensed antenna system is provided. The lensed antenna system includes a first column of radiating elements having a first longitudinal axis and a first azimuth angle, and, optionally, a second column of radiating elements having a second longitudinal axis and a second azimuth angle, and a radio frequency lens. The radio frequency lens has a third longitudinal axis. The radio frequency lens is disposed such that the longitudinal axes of the first and second columns of radiating elements are aligned with the longitudinal axis of the radio frequency lens, and such that the azimuth angles of the beams produced by the columns of radiating elements are directed at the radio frequency lens. The multiple beam antenna system further includes a radome housing the columns of radiating elements and the radio frequency lens. There may be more or fewer than two columns of radiating elements.
