摘要:
A cable television tap (500) for receiving a forward signal including an information signal and a power signal. The tap (500) includes a diplex filter (520) for receiving the forward signal and for separating the information signal from the power signal at outputs of the diplex filter (520) and a plurality of subscriber ports (535) coupled to an output of the diplex filter (520) for receiving the information signal such that the information signal can be accessed at each of the plurality of subscriber ports (535). The tap (500) also includes a removable port device (555) coupled to the other output of the diplex filter (520) for receiving the power signal, and the port device (555) has a connector (550) so that the power signal can be accessed. According to the present invention, when the port device (555) is coupled to the tap (500), the information signal can only be accessed at the subscriber ports (535), and the power signal can only be accessed at the connector (550) of the port device (555). This provides a way to separately transmit the information signal and the power signal over the subscriber property to the subscriber.
