RF Cable Assemblies

RF Cable Assemblies

The following sections describe the coaxial cable, header block, and F-connector assemblies required to support N+1 redundancy between the Cisco uBR 3x10 RF Switch, the Cisco uBR7246VXR CMTSs and the Vecima HD4040 series IF-to-RF upconverters.

Note Although you may construct and implement your own cables, we recommend using the preassembled cables and cable bundles.

Custom cables or cable components such as header blocks, crimping tools, or connectors are available from custom cable fabricators such as WhiteSands Engineering (telephone: 1 800-586 7377), at the following URL:

Coaxial Cables (Single and Bundle)

The cables approved for use in the Cisco N+1 redundancy solution, are Mini Precision RG59 (95 percent) tinned copper braid with (100 percent) foil shield. This cable is serial digital interface (SDI) rated with a 1 MHz to 3 GHz rating.

•CAB-RFSW-3x10-T (bundled cable kit:1.2-m, CMTS to RFS, F to MCX)

•CAB-RFSW-3x10-10T (bunbled cable kit:10-m, RFS to HUB, MCX to F)

•CAB-RFSW5X20TPMF (bundled cable kit, 3-m, MCX to F)

The different jacket colors are used for easy identification. The gray and brown RF cables are preterminated with the F-connectors used to connect to the Vecima HD4040 series IF-to-RF upconverter input. (See Figure 5-3and Figure 5-4 on page 5-5.)
