Ingress noise is a major concern with two-way services. PPC has developed a series of filters to control this problem. Now with the introduction of VoIP, ingress mitigation is critical in order for robust, reliable voice services to be made available.
PPC's Step Attenuators provide a fixed level of flat attenuation within the upstream frequencies only.
Low value taps produce the majority of ingress and trouble calls within a typical HFC network. This is due to the lack of sufficient reverse attenuation found in higher value taps.
Ingress mitigation has always been an important aspect of providing qualtiy upstream communications, with the introduction of VoIP and other advanced services, ingress mitigation is a must. Distortion, delays and dropped calls can all be attributed to ingress, window filters supress ingress noise allowing active services such as cable modems and STB return carriers to pass.
PPC’s SNB series is a major breakthrough in Windowed High Pass Filter performance. PPC’s signature Silencer ® Series design utilizes 100% Surface Mount Components in an extremely compact, sleek package with superior electrical and mechanical performance.
PPC’s High Pass Filters are used to isolate upstream frequencies for subscribers who do not require return path services. High Pass Filters also prevent ingress noise from propagating back to the node and disrupting active upstream services.
PPC’s SHP series filters represent a major technological breakthrough by being the first to offer such outstanding electrical performance in the compact Silencer® Series packaging.
