Note
Change of the transmission link
Exclusively suitable components that have been correctly installed/connected according to
the manufacturer’s instructions should be used in Ethernet transmission links. The trans-
mission link should be certified in each case.
Example 3 – poor execution of the cable/connector connection
In the following example, the core pairs are untwisted over an unnecessarily long distance contrary to the
manufacturer’s instructions; therefore local crosstalk is very much facilitated. In the test, such a connector is
noticeable by a high crosstalk and/or a low crosstalk attenuation “NEXT”.
