6 Characteristics and requirements
6.2 Electrical characteristics and tests
Add the following note:
NOTE For cat7 , unless the test is performed with very sensitive test equipment, it is recommended to limit the cable length to
A
50 m for a better accuracy in high frequencies.
6.3.6 Far-end crosstalk (FEXT)
Table 7 – Worst-pair PS EL FEXT(1) values
In the PS EL FEXT(1) column for Category 7, instead of:
“92,3”
read :
“91”.
6.3.10 Impedance
Replace the existing text of 6.3.10 by the following. There is no change to Figure 1.
The impedance requirement is specified by either case A or case B below as specified in the
relevant detail specification.
Case A (Fitted or mean characteristic impedance):
The impedance measured in accordance with 6.3.10.2 or 6.3.10.3 of IEC 61156-1 shall be
100 Ω ± 5 Ω at 100 MHz. In this case, the return loss shall also be
