ABSTRACT:
A broadband cable television system for delivering broadband cable television signals from a headend to a plurality subscribers includes a bridger module. The bridger module allows upgrading of the system to a much higher channel capacity or to a fiber to the service area architecture with a minimum amount of subscriber down-time. The bridger module is advantageous in that it permits CATV systems to be reconfigured without having to relocate the trunk/bridger stations. The bridger module utilizes a signal director which is capable of directing broadband television signal flow from left-to-right or from right-to-left along a trunk cable. The bridger module also incorporates plug-in passive devices, the value of which is selected in accordance with the signal loss levels between independently located distribution amplifiers.
