Abstract
A coaxial tap in a hybrid fiber coaxial cable distribution system serves subscribers with an RF signal while passing the RF signal and an equipment supply voltage to devices downstream of the tap.
Claims20
A tap for use in a hybrid fiber coaxial (HFC) cable distribution system, the tap comprising:
- a metallic housing for interconnection with an upstream hardline and a downstream hardline;
- the hardlines transporting RF signals and equipment supply voltage signals;
- the housing enclosing hardline circuits and drop circuits;
- the drop circuits for servicing subscriber ports;
- the hardline circuits including a bridge for passing only low frequency equipment supply voltage signals between the upstream and downstream hardlines;
- and,
- the drop circuits for passing only high frequency signals between the upstream and downstream hardlines;
- wherein an RF switch is for passing only RF signals between the upstream and downstream hardlines when the drop circuits are disconnected from the hardline circuits.

A tap for use in a hybrid fiber coaxial (HFC) cable distribution system, the tap comprising:
- a metallic housing for interconnection with an upstream hardline and a downstream hardline;
- the housing enclosing hardline circuits and drop circuits;
- the drop circuits servicing subscriber ports;
- the hardline circuits including a bridge for separating RF signals and equipment supply voltage signals;
- the separated equipment supply voltage signals transferred from one of the hardlines to the other hardline;
- the separated RF signals transferred to the drop circuits and back to the bridge when an RF switch status indicates the drop circuits are connected to the hardline circuits;
- and,
- the separated RF signals bypassing the drop circuits and transferred back to the bridge when switch status indicates that the drop circuits are not connected to the hardline circuits.

- the drop circuits for servicing subscriber ports;
- the hardline circuits including a bridge for separating RF signals and equipment supply voltage signals;
- the separated equipment supply voltage signals transferred from one of the hardlines to the other hardline;
- an RF switch and an RF switch state for allowing transport of the separated RF signals to the drop circuits and back to the bridge;
- and,
- an RF switch state for allowing transport of the separated RF signals back to the bridge independent of the drop circuits.
