Cable breakout assembly
First Claim
1. A cable breakout assembly, comprising:
- a breakout device including an enclosure located on a cellular telecommunication tower and configured to receive a primary power cable and connect one power line in the primary power cable with multiple secondary power lines in multiple secondary power cables;
an internal power distribution terminal located within the enclosure to electrically connect together the one primary power line in the primary power cable with the multiple secondary power lines in the multiple secondary power cables; and
a surge protection system located within the breakout device enclosure and connected between the power line in the primary power cable and the internal power distribution terminal that connects together the secondary power lines in the secondary power cables, wherein;
the primary power cable is connected between the breakout device enclosure and a base transceiver station (BTS); and
the secondary power cables are connected between the breakout device and remote radio units (RRUs) on the cellular telecommunication tower.

Abstract
A telecommunications system uses a breakout device to connect a primary power cable to different secondary power cables that connect to different remote radio units (RRUs). For example, the breakout device may include a power distribution terminal that connects −48 VDC and return power lines in the primary power cable to different −48 VDC and return power lines in the secondary power cables. In another example, the breakout device may connect a hybrid cable that includes both power lines and fiber optic lines. A surge protection system may be located in the breakout device to protect the RRUs and other electrical device from power surges. Alternatively, the surge protection system may be located in jumper power cables connected between the breakout device and the RRUs.
