TELECOMMUNICATIONS ENCLOSURE WITH A SEPARATE MOUNTABLE HINGE
The present disclosure relates to a telecommunications enclosures that can be customizable to include a hinge. That is, a separate hinge may be utilized as an add-on feature for telecommunications enclosures. The hinge can be attached to at least two different sides of an enclosure or may not be utilized at all. Such a configuration allows for flexibility of a variety of designs for a telecommunications enclosure. The hinge can be mountable to interfaces of first and second housing pieces of an enclosure. The hinge can have rotational features and/or translational features for pivoting first and second housing pieces of an enclosure between first and second positions.
The present disclosure is directed to motor system for a multi-RET actuator system. The motor system includes a rotor configured to rotate within an interior cavity of a stator, a drive shaft coupled to the rotor and to a drive assembly of the multi-RET actuator system, an annular disc surrounding the stator, the annular disc is coupled to the rotor such that rotation of the rotor causes simultaneous rotation of the annular disc, a plurality of spaced apart magnets embedded within the annular disc, a HALL effect sensor, and a motor speed controller in communication with the rotor and the HALL effect sensor. Methods for controlling the position and speed of a motor system are also described herein.

A system for managing telecommunications cables includes a cable guide bracket mounted separate from a panel. The adjustable cable guide bracket provides more cable openings than would normally fit on the panel.
A glass fiber reinforced wall for a fiber optic cable enclosure having variable wall thicknesses between stiffening ribs to improve durability against impact loads.
A module for a base station monopole has a wall defining an interior space. The wall includes an opening configured to receive electronic equipment and a vent opening in communication with the exterior of the module. A reinforcement member is secured to the wall and is positioned opposite to the opening and adjacent the vent opening. A baffle is supported adjacent the wall where the baffle has an intake opening and an exhaust opening in communication with the vent opening. The intake opening is laterally offset from the exhaust opening.
Methods of powering a radio that is mounted on a tower of a cellular base station are provided in which a direct current (“DC”) power signal is provided to the radio over a power cable and a voltage level of the output of the power supply is adjusted so as to provide a substantially constant voltage at a first end of the power cable that is remote from the power supply. Related cellular base stations and programmable power supplies are also provided.

An adapter for a cable hanger includes: first and second opposed side walls; a ceiling spanning the first and second side walls; and first and second end walls spanning the first and second side walls and merging with the ceiling. At least one of the first and second side walls and the ceiling includes a mounting hole. At least one cradle is mounted to and extends away from one of the first or second side walls, the first or second ends walls, or the ceiling.
A communications panel includes a chassis receiving one or more tray arrangements that each support one or more cassettes. Each cassette carries a plurality of ports at which connections are made between front and rear plug connectors. Each tray arrangement includes guides along which the cassettes slidably mount. The guides and cassettes are configured to enable cassettes of various size to mount to the same tray without reconfiguring the guides.
An adapter assembly includes a single-piece or two-piece multi-fiber adapter defining a recess at which a contact assembly is disposed. The adapter assemblies can be disposed within adapter block assemblies or cassettes, which can be mounted to moveable trays. Both ports of the adapters disposed within adapter block assemblies are accessible. Only one port of each adapter disposed within the cassettes are accessible. Circuit boards can be mounted within the block assemblies or cassettes to provide communication between the contact assemblies and a data network.
A radome-reflector assembly includes a generally domed reflector having a peripheral rim and a radome assembly. The radome assembly includes: an annular ring having a front wall and a side wall; a disk that fits within the ring; and an RF-compliant absorber, wherein the rim of the reflector fits within the side wall. The radome assembly further comprises a clip that engages the rim and the ring to secure the reflector to the radome assembly.

A reel for storing a cable coil includes first and second facing flanges. First, second and third cylindrical rods define a hub and have first ends attached to the first flange and opposite, second ends extending through holes formed in the second flange. A guidepost has a first end attached to the first flange and a second end passing through an opening in the second flange. A lock set allows a distance between the first and second flanges to be selected. Attachment positions of the first ends of the cylindrical rods to the first flange are manually or automatically adjustable to change a diameter of the hub. Bushings within end openings of the guidepost control the rotation payout speed of the reel, and a parking park feature is provided at the second end of the guidepost to block rotation of the reel.
