Modular distribution and signaling unit with over voltage protection for fiber optic and power cables

A method of manufacturing a distribution and signaling unit, comprising:

• forming an enclosure configured to receive a trunk cable comprising power cables and fiber optic cables;
• providing hybrid adaptors arranged in an array and extending through one or more walls of the enclosure;
• inserting a plurality of pluggable over voltage protection (OVP) modules into respective slots in the enclosure;
• and
• inserting a pluggable printed circuit board assembly (PCBA) module into a slot in the enclosure, the PCBA module including a processor configured to transmit alarm signals or voltage values measured from the power cables to a remote location.

A modular distribution and signaling system for a cellular tower, comprising:

• an enclosure configured to receive a trunk cable comprising power cables and fiber optic cables;
• hybrid adaptors arranged in an array and extending through one or more walls of the enclosure;
• one or more bus bars located in proximity to respective columns or rows of the hybrid adaptors;
• a plurality of pluggable over voltage protection (OVP) modules removably inserted into the enclosure and electrically coupled to the one or more bus bars;
• and
• a pluggable printed circuit board assembly (PCBA) module removably inserted into the enclosure and electrically coupled to at least one of the one or more bus bars, the PCBA module including a processor configured to transmit alarm signals or voltage values measured from the power cables to a remote location.

A modular power distribution unit (PDU), comprising:

• an enclosure including a plurality of walls, wherein at least one wall is a hinged front wall configured to open outwardly;
• a circuit board mounted on an interior surface of a rear wall of the enclosure;
• a plurality of pluggable overvoltage protection (OVP) modules removably inserted into the enclosure and electrically coupled to the circuit board;
• and
• wherein the circuit board provides electrical connections for the plurality of pluggable OVP modules.
