Chapter 5: Troubleshooting the Premises Wiring
A table view or graphical network representation provides the
technician with a quick and precise overview of the elements
within a home’s coaxial network. Simply connecting the test-set at
the NID, the technician can determine the topology and location
of any components and faults in the network. For coax networks
incorporating devices such as splitters, FDR technology is superior
because it will work through splitters and identify any items that
may hamper the RF performance. FDR can also help locate other
impairments of the network, including open cables, splitters, unterminated
ports, and pinched or damaged cables.
