Appendix B: 75-Ohm CATV Cable

A B: 75‐O
PPENDIX
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.
Use RG‐6 or RG‐11 CATV cable between the IFEU and MRAU, the typical lengths of which are
•
listed below.
