Abstract
A coaxial tap in a hybrid fiber coaxial cable distribution system serves subscribers with an RF signal and optionally an equipment supply voltage while passing the RF signal to devices downstream of the tap.
Claims28
A tap for use in a cable television distribution system comprising:
- a tap housing with coaxial cable ports configured to interconnect with an upstream hardline and a downstream hardline;
- the hardlines configured to transport cable television signals that are RF signals and equipment supply voltage;
- the housing enclosing hardline circuits and drop circuits;
- and,
- the drop circuits for servicing subscriber ports;
- wherein the hardline circuits do not pass RF but are configured to continuously pass an equipment supply voltage present on one of the hardlines to the other of the hardlines irrespective of whether RF signals are conveyed to the subscriber ports.

A tap for use in a cable television distribution system comprising:
- a tap housing with coaxial cable ports configured to interconnect with an upstream hardline and a downstream hardline;
- the hardlines configured to transport cable television signals that are RF signals and equipment supply voltage;
- the housing enclosing hardline circuits and drop circuits;
- and,
- the drop circuits for servicing subscriber ports;
- wherein an RF switch for passing only RF signals is configured to pass RF signals present on one of the hardlines to the other of the hardlines when circuits for conveying the RF signal to the subscriber ports cease to convey the RF signal to the subscriber ports.

A tap for use in a cable television distribution system comprising:
- a tap housing with coaxial cable ports configured to interconnect with an upstream hardline and a downstream hardline;
- the hardlines configured to transport cable television signals that are RF signals and equipment supply voltage;
- and,
- the housing enclosing circuits configured to convey the RF signals to subscriber ports and configured to pass RF signals and the equipment supply voltage between the upstream hardline and the downstream hardlines;
- wherein a bridge is configured to continuously pass equipment supply voltage but not RF signals between the upstream and downstream hardlines and an RF switch is configured to pass RF signals but not equipment supply voltage between the upstream and downstream hardlines when the RF signals do not reach the subscriber ports.
