Product acceptance testing is accomplished by 584 subjecting the product to a number of mechanical and environmental conditions and measuring any 585 resistance deviations at prescribed intervals and after completion of each conditioning sequence. In 586 addition, the product shall not show evidence of degradation with respect to the ease of mechanical 587 termination, safety or other functional attributes at any time during or after environmental conditioning. 588 Connecting hardware often contains a combination of solderless connections and a separable contact 589 interface (jack/plug interface). All connections shall be tested. Each connection that comprises the 590 connecting hardware may be isolated and tested independently or all connections may be tested as an 591 assembly. When tested as an assembly, the total combined change in contact resistance may be used 592 to determine pass and fail criteria in place of isolating individual effects of the various connections. If 593 this method is employed, care should be taken to ensure the use of the most stringent test schedule as 594 the test schedules vary by type of connection. 595 NOTE 1 This annex provides mechanical connection performance requirements for connections that are not covered by a 596 specific IEC connector standard. It is intended to replace the specifications in this annex by reference to international 597 standards, as they become available. 598 NOTE 2 Connection interfaces that conform to the mechanical and environmental performance requirements of IEC 60603-7 599 (unscreened) or IEC 60603-7-1 (screened) comply with this annex as these documents speciy appropriate tests.

Therefore, The PS Alien NEXT (PS ANEXT) model is similar to the model used for 743 NEXT. 744 Simple models assume equal lengths of disturbed and disturber links and co-location of connecting 745 hardware (patch panels). In situations where the lengths of disturbed and disturber are different, 746 corrections need to be applied which depend on the length over which alien crosstalk coupling occurs. 747 G.6.2 PS Alien NEXT between connectors 748 The PS Alien NEXT between connectors is modelled as: 749 PSANEXT = PSANEXT − 20 log( f / 100 ) Conn, dB Conn, const, dB 750 G.6.3 PS Alien NEXT between cable segments 751 The PS Alien NEXT between cables is modelled as: ⎛ L ⎞ ⎜ dα ⎟ ⎜ 100 cable, 100 m, dB ⎟ ⎜ − ⎟ 752 1 − 10 5 (G-29) PSANEXT = PSANEXT − 15log( f / 100 ) − 10 log⎜ ⎟ Cable, dB Cable, const, dB ⎜ −α ⎟ ⎜ − cable, 100 m, dB ⎟ ⎜ 5 ⎟ ⎜ 1 − 10 ⎟ ⎝ ⎠ 753 In this case L is the length over which the ANEXT coupling takes place. d 754 Refer to clause G.3.1 for a description of the length dependency portion of equation G-29.

If ANEXT coupling does not 758 occur right from the beginning of the point of measurement, the impact is reduced by the sum insertion 759 loss of the uncoupled cabling segments of disturber and disturbed links. The highest influence on the 760 overall ANEXT coupling originates from the beginning of the cabling. 761 For details of PS ANEXT predictions refer to clause G.3. 762 Excess ANEXT contributions that result from unbalanced signals and differential-to-common and 763 common-to-differential mode coupling are ignored. These can be significant at high frequencies and 764 when balance properties of the cabling are poor. 765 G.7 PS Alien ACR-F modelling 766 G.7.1 General 767 The PS Alien ACR-F (PS AACR-F) model is similar to the model used for ACR-F. 768 Each pair-to-pair alien ACR-F (AACR-F) contribution is modelled exactly the same as internal link ACR- 769 F; see clause A.4. Therefore, The PS Alien ACR-F (PS AACR-F) model is similar to the model used for 770 ACR-F. 771 Simple models assume equal lengths of disturbed and disturber links and co-location of connecting 772 hardware (patch panels). In situations where the lengths of disturbed and disturber are different, 773 corrections need to be applied which depend on the length over which alien crosstalk coupling occurs. 774 The length dependency is as described in clause G.4.2. The PS Alien FEXT is obtained by adding the 775 insertion loss to the ACR-F. 776 G.7.2 PS AFEXT between connectors 777 The PS AFEXT between connectors is modelled as: 778 PSAFEXT = PSAFEXT − 20 log( f / 100 ) Conn, dB Conn, const, dB 779 G.7.3 PS AACR-F between cable segments 780 The PS AACR-F between cables is modelled as: ⎛L ⎞ 781 PSAACR_F = PSAACR_F − 20 log( f / 100 ) − 10log⎜ d ⎟ (G-30) Cable, dB Cable, const, dB ⎜ 100 ⎟ ⎝ ⎠ 782 Refer to clause G.4.1 for a description of the length dependency portion of equation G-30. 783 G.7.4 Principles of link modelling 784 Worst case conditions occur where AFEXT coupling occurs over the full length of disturber and 785 disturbed cabling, and where all connections within each link are co-located. 786 For details of PS AACR-F predictions refer to clause G.3. 787 Excess AFEXT contributions that result from unbalanced signals and differential-to-common and 788 common-to-differential mode coupling are ignored.

This can be the case when considering the conditions at a patch 793 panel where one link terminates from a nearby location and another link terminates from a distant 794 location. See Figure A-1. The disturbing link j has pairs I from 1 to 4, and is disturbing the selected link, 795 pair k. The intent is to test the performance of the cabling based on the “coupling length”. This coupling 796 length is effectively determined by the minimum insertion loss of the disturbing IL and disturbed link j 797 IL . k Disturbing link j IL i,j AFEXT k,i,j IL k Disturbed link Coupling length 798 799 Figure G.3: Example of increased impact of PS AFEXT. 800 In Figure G.3 the impact of the signal-to-noise ratio (SNR) at the near end receiver of the long channel 801 is considered. 802 G.7.5.1 Normalization for the coupling length 803 It is assumed that the coupling properties of cabling are consistent over length. 804 Over the coupling length, the AACR-F is defined as: 805 AACR − Fcoupled = AFEXT − IL (G-31) k, j k j 806 For nominally compliant cabling, the scaled ACR-F over the coupled length is given by: ⎛ Lj ⎞ ⎜ ⎟ 807 AACR − Fcoupled = AACR − F − 10 ⋅ log⎜ ⎟⎟ (G-32) k, j 100m ⎜ 100 ⎝ ⎠ 808 Therefore: ⎛ Lj ⎞ ⎜ ⎟ 809 AACR − F = AACR − Fcoupled + 10 ⋅ log⎜ (G-33) 100m k ⎜ 100 ⎟⎟ ⎝ ⎠ 810 If the coupling were to take place over the length of the disturbed link, the relationship for nominally 811 compliant cabling is: ISO/IEC JTC 1/SC 25N1318c.doc 49 11801 1 st PDAM 1.2 © ISO/IEC:2007 – 50 – ISO/IEC JTC 1/SC 25 N 1318 2007-05-02 ⎛L ⎞ 812 AACR − Fnormalized = AACR − F − 10 ⋅ log⎜ k ⎟ (G-34) k 100m ⎜ 100 ⎟ ⎝ ⎠ 813 ⎛ Lj ⎞ 814 AACR − Fnormalized = AACR − Fcoupled + 10 ⋅ log⎜ ⎟ − 10 ⋅ log⎛⎜ L k ⎞⎟ (G-35) k k ⎜ 100 ⎟ ⎜ 100 ⎟ ⎝ ⎠ ⎝ ⎠ ⎛ IL j ⎞ ⎜ ⎟ 815 AACR − Fnormalized = AACR − Fcoupled + 10 ⋅ log⎜ (G-36) k k ⎜ IL ⎟⎟ ⎝ k⎠ 816 The log ratio of lengths can be converted to a log ratio of insertion losses. It is suggested that the 817 average insertion losses of all pairs @ 250 MHz be used to compute the ratio. 818 G.7.5.2 Normalization for signal strengths 819 To correct for the coupling length, assuming the disturbed link is longer than the disturbed link and the 820 insertion loss of the coupling length (in this case the insertion loss of the disturbing link) is to be tested 821 requires a normalization that is equal to: 822 IL − IL (G-37) disturbed disturber 823 The AACR − Fcoupled is then computed as in equations (G-38) through (G-40) k 824 AACR − Fcoupled = AFEXT − IL − IL + IL = (G-38) k k j k k 825 AACR − Fcoupled = AFEXT − IL − ⎛⎜ IL − IL ⎞⎟ (G-39) k k k ⎝ j k⎠ 826 AACR − Fcoupled =AACR − F + ⎛⎜ IL − IL ⎞⎟ (G-40) k k ⎝ k j⎠ 827 In other words, the measured AFEXT needs to be adjusted “improved” by the difference of the insertion 828 losses of disturbed and disturbing links in order to reflect the AFEXT of the coupled length. 829 G.7.7.3 Total normalization 830 By combining the normalization for coupling length and the scaling for length, the correction to be 831 applied to every AFEXT result between a disturbed and a disturbing link becomes: ⎛ Lj ⎞ 832 AFEXT + IL − IL + 10 ⋅ log⎜ ⎟ (G-41) k, j k j ⎜L ⎟ ⎝ k⎠ 833 The log ratio of lengths can be converted to a log ratio of insertion losses.

These cables may not be compatible with all connecting hardware. 3) See clause 11 of ISO/IEC 11801 Ed.2. 4) Should be minimized to make best use of duct and cross-connect capacity (see clause 10 of ISO/IEC 11801). If the cable will be terminated in a plug, e.g. flexible cables, then cable unit diameters above 9 mm may not be compatible with all connecting hardware (see clause 10 of ISO/IEC 11801). 5) For certain applications (e.g. precabling buildings in cold climate) a cable with a lower temperature bending performance of -30 °C may be required. 6) This is an indication for cable performance. This results in a maximum pulling force of 50 N/mm² times copper conductor cross-section, excluding screens if present. A cu min is the minimum copper cross section. Additional strength members increase the pulling strength. 908 ISO/IEC JTC 1/SC 25N1318c.doc 54 ISO/IEC JTC 1/SC 25 SC 25 N 1318 2007-05-02 909 Table 2 - Electrical characteristics of balanced cables
