Apparatus for distributing RF signals and AC power to taps
First Claim
1. A system for distributing multimedia information from a headend unit to a subscriber, the system comprising:
- 1) a network media operative to distribute a composite AC power signal and RF signal, wherein the RF signal contains multimedia information originating from the headend;
2) a tap including;
a) a composite input terminal coupled to said network media for receiving said composite signal,b) a plurality of RF output terminals to which said RF signal received by said composite input terminal is fed, andc) an AC output terminal to which said AC signal received by said composite input terminal is distributed;
3) a power distribution unit including;
a) an input terminal connected to said AC output terminal via a power line and receiving the AC power signal on said power line,b) a plurality of AC output terminals to which the received AC power signal is fed; and
c) a limiter disposed within said power distribution unit and operative to limit a maximum output current of the AC power signal fed to the AC output terminals.

Abstract
A method and system for distributing multimedia signals to a subscriber from a headend unit. The multimedia signals are transmitted on a network media as a composite RF and AC signal. A passive unit is upgraded by with a circuit having connectors that separates the AC from the RF signal. The signals are split in the upgraded passive unit. The AC signal is fed to a power distribution unit which generates an AC output signal that is surge protected, RF filtered and current limited. The RF signal and AC output signal are separately fed to a customer interface unit where the RF signal is decoded and transmitted to a subscriber. By providing a passive unit where the AC and RF signal are separated in the same unit, the system can be upgraded with a power distribution unit when AC signals are required to supply power to subscriber equipment.
