Coaxial Connector and Cable Specifications

The Cisco uBR905 router connects to the HFC cable system with a type-F, right-angle, PCB-mount
connector manufactured by Amp (model number 531-40047). The body is die cast out of zinc, with a
tin-lead plating. The round, center contact is made of phosphor bronze, with a tin-lead plating. The
insulator is polypropylene and will accept a coaxial cable center conductor with a diameter ranging
from 0.022 inch (0.056 mm) to 0.042 inch (1.07 mm).
The coaxial cable used to connect the Cisco uBR7200 series universal broadband routers at the headend
should be very high-quality cable because imperfections that do not visibly affect video transmissions
can significantly affect digital data transmissions. In particular, poor insulation, improperly installed
additional outlets, the condition and length of the cable's center conductor, and the quality of the cable
can negatively affect the connectivity and performance of the cable access router for digital data
transmission.
