Abstract

A transition assembly for interconnecting a hybrid trunk cable and electronic equipment includes: an enclosure having first and second ends, first and second side walls, and a cavity; a hybrid trunk cable comprising first and second sets of pluralities of power conductors and a plurality of optical fibers, wherein the first and second sets of power conductors enter the enclosure at the first end; first and second sets of pluralities of connectors mounted to at least one of the first and second side walls; and an overvoltage protection module (OVP module).

Claims

1. A transition assembly for interconnecting a hybrid trunk cable and electronic equipment, comprising:

an enclosure having first and second ends, first and second side walls, and a cavity;

a hybrid trunk cable comprising first and second sets of pluralities of power conductors and a plurality of optical fibers, wherein the first and second sets of power conductors enter the enclosure at the first end;

a plurality of connectors mounted to at least one of the first and second side walls; and

an overvoltage protection (OVP) module comprising;

an OVP unit mounted in the enclosure and configured to create an open electrical circuit when experiencing a voltage higher than a predetermined threshold;

a first contact mounted in the enclosure and connected with the first set of power conductors;

a second contact mounted in the enclosure in electrical isolation from the first contact, the second contact connected with the second set of power conductors;

a first OVP conductor connected between the first contact and the OVP unit;

a second OVP conductor connected between the second contact and the OVP unit;

a third contact mounted in the enclosure and connected with the connectors;

a fourth contact mounted in the enclosure in electrical isolation from the third contact, the fourth contact connected with the connectors;

a third OVP conductor connected between the OVP unit and the third contact; and

a fourth OVP conductor connected between the OVP unit and the fourth contact.

2. The transition assembly defined in claim 1, wherein the connectors are hybrid connectors.
