RF Cable Assemblies

RF Cable Assemblies

The following sections describe the coaxial cables, header blocks, and F-connector assemblies required to support N+1 redundancy in networks using the RF switch when the Vecima HD4040 series IF-to-RF upconverter is used and the Cisco uBR10012 CMTSs chassis is populated with either the

Cisco uBR10-LCP2-MC16xline cards or the Cisco uBR10-LCP2-MC28x.

Note Although you may construct and implement your own cabling system according to the specifications outlined here, We recommend using the Cisco N+1 redundancy cabling solution designed specifically for this CMTS feature (Cisco part numbers CAB-RFSW-3X10-T and CAB-RFSW-3X10-10T for pre assembled, terminated 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), or at the following URL:

Coaxial Cables

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

•CAB-RFSW-3X10-10T (bundled cable kit: 10-m, RFS to HUB, MCX to F)

•CAB-RFSW-3X10-T (bundled cable kit: 1.2-m, RFS to UPx, MCX to F)

•CAB-RFSW520TIMM (bundled cable kit: 1-m, MCX to MCX)

Figure 4-3and Figure 4-4 on page 4-5show header blocks that are cabled using the Cisco cable kit CAB-RFSW-3X10-10T.

Note The header block shown in Figure 4-3 on page 4-5is cabled for a Cisco uBR-MC16xcard; the header block in Figure 4-4 on page 4-5is cabled for the Cisco uBR-MC28xcard.
