Noise Suppression Filters

A high pass filter attenuates ingress and noise in the sub-low portion of the cable network. Placed on a non-active return at the subscriber's drop, high pass filters effectively eliminate the major source of ingress in a HFC system, the customer's home, which is unmanageable. Realizing the fact that many installation locations are available, side of the house, tap ports, lock boxes and pedestals, Eagle Comtronics offers solutions to fulfill all your installation needs. Special low frequency models are available to block low frequency noise, commonly found in the 5-12 MHz band, while still passing the majority of the return band. This enables significant noise reduction while maintaining DOCSIS compliance. 

A window filter attenuates ingress and noise in the sub-low portion of the cable network. It is similar to a high pass filter, with the added feature of a bandpass filter, which permits a return signal to pass from the subscriber to the cable operator. This allows the cable operator to offer digital set tops, modems and telephony along with an excellent method of ingress suppression. Continuing to realize that many installation locations are available, side of the house, tap ports, lock boxes and pedestals, Eagle Comtronics offers solutions to fulfill all your installation needs.
