ELECTROLINE
CPIM (CLEARPath Integrated Module)

Managing Ingress in Cable Networks

The CPIM is a return path switch that can be installed in major brands of optical nodes, distribution amplifiers and line extenders to help manage ingress in the return path. Designed as a retrofit for existing nodes and amplifiers, it preserves the value of already installed equipment. The CPIM has all the functionality of Electroline's current field switching return path module, the CPM-3. However, its main advantage is that one CPIM contains up to four return path switches, thereby managing ingress in up to four distribution areas. To determine where the ingress is located, the CPIM selectively switches a 6 dB pad into the return path. In locations where ingress is severe, the CPIM can turn off the entire upstream band in a specific segment until the source is repaired. The CPIM utilizes a smooth switching transition that will not disrupt high-speed data services. The effect of the return path switching is displayed on a spectrum analyzer or a return path monitoring system such as CLEARPath. If the ingress associated with the CPIM is reduced by 6 dB (or disappears when switched off), it indicates that the source of ingress must be further downstream from that location. It is then a matter of switching the CPIM units installed deeper in the cable distribution plant to localize the origin of the ingress.
