Longest Extension Cable example

The length of cable used in a system hasa direct influence on the load of a

system.

The second in- line trunk- splitter has two extension cables connected to it, with lengths of 20 m and 50 m.

When determining the cable length of a Trunk-outlet or Tap-off outlet, the longest extension cable only is taken in to account.

Therefore, the total extension cable lengthfrom a single Trunk-outlet of the CCU is calculated as 10+50= 60 m (196.8 ft.)

10 m (32.8 ft.)

50 m (164 ft.)20 m (65.6 ft.)
