6. CABLE TERMINATION
In this section, list of tools, materials and the method for cable termination are
described. The list of applicable cable is shown in Table 6-1.
Notes
1
In 1+1 system, the difference between the No.1 channel IF cable length
and the No.2 channel IF cable length should be within 100 m.
(differential absolute delay time: within 500 ns)
2
When the N (Male) straight connector is attached to the IF cable, use of
the TNC (Male) - N (Female) (NJ-TNCP-LA) L-angle adapter is needed
to connect to the IDU.
3
Use shielded cables which are connected to the D-Sub/RJ-45 connector
to suppress interference from affecting the signal and to reduce
electromagnetic radiation which may interfere with other signal cables.
