Page 4 of 49 1. Summary Three communication channels have been subjected to an electrical qualification test programme to verify that they comply with generic cabling standards. The three channels are all four connector model channels. Channel no. 1 uses a double foil shielded horizontal cable for 600 MHz, F/FTP 600, 1711163. Channel no. 2 uses a braid and foil shielded horizontal cable for 600 MHz, S/FTP 600, 57893. Channel no. 3 uses a braid and foil shielded horizontal cable for 1200 MHz, S/FTP 1200, 1499102. Cords, Wall Outlets and Patch Panels are the same for the three types of channels. Transmission measurements are performed on all three types of channels and on one short channel. External crosstalk parameters are measured for channel no. 1. Coupling attenuation is measured for the three types of horizontal cables. Coupling attenuation for the two braided cables is equal to or better than coupling attenuation of the foil shielded cable. It is therefore concluded that the external crosstalk performance of the channels with the braided horizontal cable is equal to or better than that of channel no. 1. The channels for this electrical performance test were assembled and delivered to DELTA by the client. The channel testing has been performed under laboratory conditions at the European Cabling group of DELTA. This report firstly gives a detailed description of the channels under test. Then the conclusion is given followed by the test results. At last an overview of the test procedures and applied standard are given.

Page 42 of 49 6. Test procedures The tests carried out on the communication channel under test are performed according to the standard: IEC 61935-1 Testing of balanced communication cabling in accordance with ISO/IEC 11801-Part 1: Installed cabling. The test methods are detailed in test procedures worked out by DELTA and approved by DANAK. In this section the procedures are described briefly. 6.1 Electrical test The electrical tests on the communication channel under test are performed according to the procedures described in this section. The performed tests are shown in the following table. The floor cable is stretched on a non-conductive surface.

Terminal end and equipment end are connected to one balun each. The measurement uncertainty for attenuation is ±0.15 db for attenuation up to 40 db and ±0.5 db for attenuation up to 60 db.

The return loss of the channel under test is measured with the far end terminated with a resistance of the specified characteristic impedance of the channel under test, Z0. The measurement uncertainty for return loss is dependant of the measured return loss value. The error band is specified in the table below: Measured return loss Error band 5 db 4.8 RL 5. 2 10 db 9.7 RL 10. 3 15 db 14.5 RL 15. 5 20 db 19.2 RL 20. 9 25 db 23.6 RL 26. 7 30 db 31.1 RL 42. 2 40 db 34 RL
Page 45 of 49 6.1.3 Near end crosstalk NETWORK ANALYSER PLOTTER/ PRINTER S PARAMETER TEST SET/ DIVISER LOAD LOAD BALUN BALUN DEVICE UNDER TEST Figure 5 Test set-up for near end cross talk measurements. Near end cross talk, NEXT, is measured as the attenuation from one pair to the others and these measurements are repeated for all pair combinations. In the far end all pairs are terminated with a resistor with a value of the quoted characteristic impedance of the component under test. The measurement uncertainty for NEXT is dependant of the level of measured NEXT. The uncertainty is shown in the table below: Measured NEXT Uncertainty 40 db ± 0.5 db 60 db ± 0.6 db 70 db ± 0.8 db 80 db ± 1.7 db 6.1.4 Powersum near end crosstalk (PSNEXT) PSNEXT is calculated according to the formula: PSNEXT = 10log( 10 + 10 + 10 x1 / 10 x2 / 10 x3 / 10 ) where x1, x2, x3 are the pair-to-pair cross talk measurements in db between the selected pair and the other three pairs. The measurement uncertainty is the same as for NEXT measurements.
Page 46 of 49 6.1.5 Attenuation to crosstalk loss ratio (ACR) Attenuation to Crosstalk Ratio, ACR is calculated for each pair considering the minimum near end cross talk, NEXT measured for the six pair combinations. The measurement uncertainty is the same as for NEXT measurements. 6.1.6 Power sum ACR (PSACR) PSACR is calculated according to the formula: PSACR = 10 log(10 + 10 + 10 + 10 x1/10 x2 /10 x3 /10 x4 /10 Where x1, x2, x3, and x4 are the pairs ACR measurements in db. The measurement uncertainty is the same as for NEXT measurements. ) 6.1.7 Attenuation to crosstalk ratio-far end NETWORK ANALYSER PLOTTER/ PRINTER LOAD LOAD S - PARAMETER TEST SET/ DIVISER DEVICE UNDER TEST BALUN BALUN Figure 6 Test set-up for far end crosstalk measurements. ACR-F is calculated from the measured values of far end crosstalk, FEXT, and attenuation, ATT. ACR-F = FEXT - ATT The measurement uncertainty is the same as for NEXT measurements.

The length of the measured part of the component or cabling under test is 6 m. The measurement result of the network analyser is corrected for insertion loss of the balun and absorbing clamp. The result is also corrected for the reflected wave at the input of the clamp. The result is evaluated by a limit curve, which is horizontal up to 100 MHz and has a slope of 20 db/octave up to 1 GHz. The value for which the limit curve intercepts the Y axis is the coupling attenuation. The measurement uncertainty for coupling attenuation is ±6 db.
Page 48 of 49 6.1.9 DC loop resistance DC loop resistance is measured for each conductor in a pair. The loop resistance is calculated by adding the resistance of each conductor. The measured value is corrected for the temperature of the test object in order to obtain the resistance at 20 C. 6.1.10 Propagation delay Propagation delay is measured by determining the phase delay of a signal transmitted through the cable. δ = ϕ 2 π f where ϕ is the phase delay. f is the frequency in Hertz. The measurement uncertainty for delay is ±1%. 6.1.11 Delay skew Delay skew is calculated as the difference between the maximum and minimum propagation delay over the four pairs at each frequency. The measurement uncertainty for skew is ±10%.
Page 49 of 49 6.1.12 Alien crosstalk tests Alien crosstalk was measured for the channel mounted in a six around one configuration. Alien crosstalk was obtained by measuring the S21 parameter with a network analyser. The channels were attached to baluns, which perform the asymmetric to symmetric conversion of the signal. The baluns were placed on a metallic ground plane. Alien NEXT was measured from the patch panel end of the channels. All pairs in the far end were terminated. The pairs not under test in the near end were terminated with loads providing differential and common mode termination. With one victim and 6 disturbers there are 96 different combinations, 24 for each victim pair. All 96 combinations were measured. For alien FEXT measurements the near end and far end of the measured pairs were terminated. Alien FEXT was measured as the coupling from the far end of the disturber to the near end of the victim. There are again 96 combinations. For each victim pair, power sum crosstalk was calculated as the power sum of 24 pair to pair results. The signal to noise ratio, due to alien FEXT (which is Power Sum Alien Attenuation to Crosstalk ratio Far end, PSAACR-F) was calculated by subtracting the measured attenuation of the victim channel (the disturbed pair) from the PS AFEXT. (This parameter was formerly called PSAELFEXT). Note: Values in graphs for alien crosstalk, which are lower than 85 db comes from the noise floor of the network analyzer. This noise floor has a jump at 15 MHz, which may be seen at some graphs. It has nothing to do with the performance of the sample under test. The measurement uncertainty for alien crosstalk measurements are the same as for NEXT measurements. 6.2 Test software Test software according to information in the table below is used for the conducted tests.
