^ The shielding effectiveness deteriorates considerably when
the cable length increased, for example, metres.

Fig. Thus over
engineering avoided and total system costs are kept minimum.
Some cables have greater shielding effectiveness compared standard
connector. 3.7 “Optimal system”
There one main precondition for “optimal system”: All the single
components should have the same shielding effectiveness.98: Shielding effectiveness measurements
■=> The measurement results for pre-assembled cables depend on
the shielding effectiveness the connector
The shielding effectiveness pre-assembled cable can only good
as that the "weakest component".5. However, must taken into account that this only valid for
a cable length metre.6.64
3. That is, both
components are equivalent far their shielding
effectiveness concerned.
^ conclusion, can said that the characteristic curve of
the cable approaches that the connector
