14.3 Routing the Cable
After connecting the cable to the ODU it can be routed and secured using standard cable
routing and securing techniques. When the cable is in place it can then be cut to the desired
length.
14.4 Fitting a Surge Arrestor
If you have opted to fit a Surge Arrestor, it should be installed as described in Section A1.5
“Lightning Protection”
14.5 Customer Cable Termination
The two channels can be separated by means of a patch panel which may include Baluns for
transmission over 75 Ohm co-axial unbalanced lines. Such equipment should conform to the
requirements of C.C.I.T.T. G703. An example of a Balun is shown below. It allows the
transmit and receive data carried over a 75 Ohm cable to be converted to a balanced form for
transmission over a 120 Ohm signal balanced twisted pair.
