Abstract
Some embodiments of the present disclosure are directed to a hybrid distribution unit that can distribute both power and data connections from a power and fiber cables (or from a hybrid cable containing both power and fiber) within a compact enclosure that helps reduce the overall footprint of the hybrid distribution unit mounted on a cellular tower. Some embodiments may also include circuit protection features, such as fuses or circuit breakers. Other embodiments may be described or claimed.
Claims31
A hybrid distribution unit apparatus comprising:
- an enclosure having an interior portion, exterior portion, a bottom, and a length;
- at least two pairs of bus bars each pair comprising:
- a first elongated bus bar extending along at least a portion of the length of the interior portion of the enclosure and configured to connect to a first set of one or more power cables in the interior portion at the bottom of the enclosure;
- a second elongated bus bar extending along at least a portion of the length of the interior of the enclosure and configured to connect to a second set of one or more power cables in the interior portion at the bottom of the enclosure;
- a plurality of adapters extending from the exterior portion of the enclosure, wherein at least one adapter includes a first set of one or more connectors configured to connect one or more power jumper cables to the first and second elongated bus bars and a second set of one or more connectors configured to connect one or more fiber optic jumper cables to ends of one or more fiber optic cables entering the interior portion of the enclosure from the bottom of the enclosure;
- and
- a plurality of fuses, wherein at least one fuse from the plurality of fuse is coupled between a respective adapter from the plurality of adapters and the first bus bar.
