Passive Intermodulation (PIM)
Passive Intermodulation (PIM)
In today’s rapidly growing telecommunications environment, maintaining capacity and network performance is more important than ever. One of the most common issues operators face is Passive Intermodulation (PIM), a subtle but significant source of signal degradation that can affect the quality of voice, data, and video services.
What is PIM, and Why is it a Problem?
PIM occurs when two or more signals at different frequencies interact in a passive, non-linear connection, creating unwanted intermodulation products. These additional signals can interfere with the primary signals, leading to signal loss, dropped calls, and network downtime.
External PIM refers to PIM interference that occurs outside the network equipment itself, often as a result of signal interference with external metal objects near antennas or cables. External PIM can be particularly challenging to identify and resolve, as the source of interference lies outside the controlled telecommunications infrastructure.
Solving PIM with FIMO's PIM Shield
At Bredengen AS, we understand the importance of providing solutions that reduce PIM and improve network performance. This is where FIMO's PIM Shield comes into play. FIMO, a leading player in telecommunications components, has developed a specialized range of products designed to effectively address PIM challenges.
Do you need help?
Troubleshooting PIM is an important but often time-consuming process that requires specialized equipment and the right expertise. Primarily, it involves locating where the PIM interference occurs, whether internally in network equipment (such as connectors, cables, or antennas) or externally in the surrounding environment, like metal objects near base stations.
PIM Test Probe
The PIM test probe is used in conjunction with other test and measurement equipment to accurately locate external PIM sources in the field
PIM Blanket, PIM RF Absorber Kit, PIM Foil
Temporary RF barriers that can be used on rooftops, both in front of and behind base station antennas, to isolate sources of Passive Intermodulation (PIM).
Once the source of PIM is identified, the focus shifts to implementing shielding solutions that prevent further interference and protect the network from new PIM generation. This is where FIMO's PIM Shield product portfolio becomes a critical resource.
