With increased bandwidth to 750 MHz and higher, maintaining the correct carrier levels at the subscriber is becoming more difficult. Adding to this problem is the increased number of TV’s and other devices used. PPC has designed a series of filters to balance the full spectrum of carriers.
In today’s marketplace, PVRs, Digital set-tops, VoIP, HSD, and a TV in every room is placing a strain on CATV signal levels. The ATP Series is designed to provide accurate signal levels to each device connected to the drop.
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.
PPC’s forward path attenuators provide a fixed level of attenuation within the downstream frequencies without affecting upstream frequencies. Typical applications include attenuation of overamplified signals generated by drop amplifiers at the first input.
With the introduction of digital video, most set-top manufacturers specify a maximum slope factor in order to function properly. PPC’s equalizers provide a correction to excessive cable loss and passive devices
PPC’s cable simulators are used to correct excessive positive tilt. Typical applications include signal input correction for digital set-top converters and head-end equipment applications.
