I. Overview of RPM Series
Ericsson RPM (Radio Product Module) is a cable series specially designed by Ericsson for communication equipment, widely used in base station, core network and transmission equipment connections. The RPM series is mainly divided into the following categories:
- Signal Cables: For data/control signal transmission
- Power Cables: For device power supply
- Fiber Optic Cables: For high-speed data transmission (CPRI/eCPRI)
- Coaxial Cables: For RF signal transmission
