75-OHM CATV CABLE REQUIREMENTS AND SPECIFICATIONS
The 75-Ohm CATV Cable:
• connects the IFEU to MRAU(s) and the MRAU(s) to the SRAU(s)
• transmits (FWD) multiband and receives (REV) IF signals
• delivers DC electrical power to the RAUs. The Spectrum IFEU DC voltage output is +54Vdc nominal. If the
IFEU reaches its current limit, a current-limiting circuit protects it.
• carries configuration and status information
• uses 75
type-F connectors with captive center pins.
CATV Cable Requirements
Belden CATV cable or equivalent is required (see Figure 2).
• For the RG-6 cable, use a Belden 1695A Coax.
• For the RG-11 cable, use a Belden 7732A Coax.

NOTE: TE Connectivity requires solid copper center conductor CATV cable for proper DC voltage to the RAU and maximum
distances.
