Corrigendum 1 to Amendment 2 – 2 – ISO/IEC 11801

5.7.5.1 General requirements
Replace the second sentence as follows:

Until ISO/IEC 14763-2 is published, relevant information can be found in
ISO/IEC TR 14763-2.
6.4.9 Current carrying capacity

Replace the existing first paragraph by the following paragraph and Table:

The minimum current carrying capacity for channels of Classes D, E, EA, F and FA shall be in

accordance with Table 84. This shall be achieved by an appropriate design.

F combined length of patch cords/jumpers and equipment cords (m)
X the ratio of cord cable insertion loss (dB/m) to backbone cable insertion loss (dB/m)
NOTE 1 Where channels contain a different number of connections than in the model shown in Figure 13, the fixed
cable length is reduced (where more connections exist) or increased (where fewer connections exist) by 2 m per
connection for Category 5 cables and 1 m per connection for Category 6, 6 , 7 and 7 cables. Additionally, the
A A
NEXT, return loss (RL) and ACR-F performance should be verified.
NOTE 2 For operating temperatures above 20 °C, B should be reduced by 0,2 % per °C for screened cables;
0,4 % per °C (20 °C to 40 °C) and 0,6 % per °C (>40 °C to 60 °C) for unscreened cables.
a
Applications limited by propagation delay or delay skew may not be supported if channel lengths exceed 100 m.
b
This length reduction is to provide an allocated margin to accommodate insertion loss deviation.

9.2.2.6 Current carrying capacity
Replace the existing first paragraph and table by the following:

The minimum d.c. current carrying capacity shall be as indicated in Table 64.
Table 64 – Current carrying capacity for channel
