Cisco uBR-3x10 RF Switch Hardware Installation and Cabling Guide

Chapter 4 Cabling the RF Switch With the Cisco uBR10012 CMTS Cable Interface Line Cards
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-MC16x line 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).

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 4-3 and Figure 4-4 on page 4-5 show 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 4-5 is cabled for a Cisco uBR-MC16x card; the header
block in Figure 4-4 on page 4-5 is cabled for the Cisco uBR-MC28x card.
