Coaxial Cables
The coaxial cable used to connect the Cisco uBR10012 universal broadband routers at the headend
should be very high-quality cable.
Cisco recommends that you use a headend-grade coaxial cable or a quad-shield coaxial cable to connect
the cable
modem cards to the HFC network. The center conductor must be straight and extend 1/8 in.
(3.2 mm) beyond the end of the connector, and the connector should be securely crimped to the cable.
The following headend cables are recommended:
• 59-series cable (preferred) —20 AWG (0.032 in./0.81 mm diameter) silver plated, copper-clad, steel
center conductor; bonded foil inner shield; 95% braid second shield; non-bonded foil third shield;
95% braid fourth shield.
• 59-series quad shield—20 AWG (0.032 in./0.81 mm diameter) copper-clad steel center conductor;
bonded foil inner shield; 53% braid second shield; non-bonded foil third shield; 34%-35% braid
fourth shield.
• 6-series quad shield—18 AWG (0.0359 in./0.91 mm diameter) copper-clad steel center conductor;
bonded foil inner shield; 60% braid second shield; non-bonded foil third shield; 40%-42% braid
fourth shield.
