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.
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.
