Routing The Cable; Fitting A Lightning Protection Unit; Customer Cable Termination - Motorola PTP 600 Series User Manual

CAUTION: Do not over tighten the glands as the internal seal and structure may be
damaged. See Figure 40 for an example of an over tightened cable gland.

15.3 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.

15.4 Fitting a Lightning Protection Unit

If you have opted to fit a Lightning Protection Unit, it should be installed as described in
Section 10 "Lightning Protection".

15.5 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.
