APPENDIX A Cables and Connectors
A.1 75 Ohm CATV Cable
• Connects the Expansion Hub to the RAU(s)
• Transmits multiband (downlink) and receives (uplink) IF signals
• Delivers DC electrical power to the RAUs. The Fusion Hub’s DC voltage output is
54V DC nominal. A current limiting circuit is used to protect the Hub if it reaches
its current limit
• Carries configuration and status information
• Use 75 Ohm type-F connectors with captive centerpins
• Lengths:
RG-59:
• Minimum: 0 meters (0 ft.)
• Maximum: 150 meters (492 ft.)
RG-6:
• Minimum: 0 meters (0 ft.)
• Maximum: 170 meters (558 ft.)
RG-11:
• Minimum: 0 meters (0 ft.)
• Maximum: 275 meters (902 ft.)
Recommended minimum and maximum CATV cable lengths vary depending upon
which CATV cable you use.
Be sure to test cable termination before installing the cable.
CommScope CATV cable or equivalent is required:
CommScope 20655V for RG-59. This cable is illustrated in Figure A-1.
CommScope 2279V for RG-6. This cable is illustrated in Figure A-2.
CommScope 2293K for RG-11.This cable is illustrated in Figure A-3.
