2. SURVEY OF THE WORK

3P has performed qualification testing of Telebox two connector permanent links according toClass E / Category 6A requirements. The permanent links are constructed using individual foilA

and overall braid screened horizontal cable and screened RJ 45 connecting hardware.

Testing was carried out under laboratory conditions at 3P in November 2012.

The applied permanent link configuration is according to definition in ISO/IEC 11801, CENELECEN 50173-1 and ANSI/TIA/EIA-568-B.1. No consolidation point and totally 90,0 metreshorizontal cable length is applied. Furthermore, it has been verified that the performance of asimilarly configured short two connector permanent link, modified to have 30,0 metres ofhorizontal cable between wall outlet and patch panel instead of 90,0 metres, also complies withthe requirements. This additional testing concerns the critical noise parameters of return loss, andpair-pair and power sum near end crosstalk.

The qualification testing was carried out according to Class E requirements of edition 2.2 ofA

ISO/IEC 11801 and CENELEC EN 50173-1:2011, Category 6A requirements ofANSI/TIA-568-C.2, and the requirements specified in IEEE P802.3an. The requirements to aliencrosstalk have been verified to comply based on passing of the threshold coupling attenuation limitas specified in edition 2.2 of ISO/IEC 11801.

The 90,0 metres permanent link was assembled by 3P and consisted of:

• Screened RJ 45 plug from Telebox

• Wall outlet with screened keystone jack from Telebox

• 90,0 metres of individual foil and overall braid screened horizontal cable in LSFRHF versionfrom Draka

• Screened patch panel from Telebox


The short length permanent link was also assembled by 3P.

Testing was conducted using the patch panel, P/N MLB246ASx. The patch panel, P/NLB246ASx, is also covered by the positive conclusion of testing. The two types of patch panelsare having the same printed circuit board design and both pass the transfer impedancerequirements.

Transfer impedance of the horizontal cable, and the keystone jack and patch panels terminatedwith the horizontal cable of the permanent link and RJ 45 plug from Telebox, has been evaluatedin connection with the present permanent link testing and complies with the specified transferimpedance limits for components of a Class E / Category 6A permanent link.A

of 47


The electrical performance of the horizontal cable, keystone jack and patch panels has beenmanufacturer verified.

The overall result of testing is that the Telebox two connector permanent link in every respectcomplies with the screened Class E / Category 6A requirements.A

A 3P qualification is therefore granted for the Telebox two connector permanent link,consisting of a combination of the following horizontal cable, connecting hardware and RJ 45plug:

• Individual Foil and Overall Braid ScreenedHorizontal Cable from Draka, Type Silverline Gold 1000

• Screened Keystone Jack from Telebox, P/N TB806ASxhaving PCB Marking 001-8074

• Screened Patch Panels from Telebox, P/N MLB246ASxandP/N LB246ASxhaving PCB Marking Cat.6A 001-0895

• Screened RJ 45 Plug from Telebox, P/N TA3368DS

for screened Class E / Category 6A installations.A

Qualification of the Telebox two connector permanent link for screened Class E / Category 6AA

installations will be valid until failure to pass one of the maintenance of qualification testprogrammes, which will be performed at 12 months intervals. Also, the qualification is made onthe premise that all keystone jack, patch panels, horizontal cable and RJ 45 plug have andmaintain quality and performance levels corresponding to the ones of the components of thepresently tested permanent link, are correctly terminated according to the Telebox instructions,and are installed using proper workmanship in compliance with all specified and relevantinstallation guidelines.

5. SUMMARISED TEST RESULTS

Summarised test results are presented in the following clauses, while recordings of electricalperformance versus frequency are found in the appendix. The tables in the present sectiongenerally inform about the headroom to a specified worst case limiting function which is presentedunder the table concerned. The various recordings of electrical performance versus frequency inthe appendix contains, in red colour, the limiting function specified for the parameter in question.

3P has performed testing according to Class E / Category 6A requirements.A

The permanent link is constructed according to the the two connector model using individual foiland overall braid screened horizontal cable and screened RJ 45 connecting hardware.

5.1 Nominal Impedance

Nominal impedance has been specified as 100 Ω. Consequently return loss measurements havebeen performed using a 100 Ω end termination.

CENELEC EN 50173-1 and ISO/IEC 11801 specify that the nominal impedance is a design valuewhich is not intended for testing. Return loss is the relevant parameter applied for testing ofreflections caused by characteristic impedance variations in cables, return loss of connectors andmismatch of impedances of the cables of links and channels.

Results of return loss measurements are presented in clause 5.2.

5.2 Return Loss

Summarised results of testing are found in table 5.2, and include all four tested pairs measuredfrom both ends of the permanent links. Recordings of return loss versus frequency from both endsof the 30,0 metres permanent link are found in pages 26 - 27 of the appendix.

40 - 398 MHz: 34,0-10log(f) dB

398 - 500 MHz: 8,0 dB,

where f is frequency in MHz. Calculated requirements more strict than 21,0 dB areequalled to this value.

: The first column is measurement of the 90,0 metres two connector permanent link,2

while the second column concerns measurement of the 30,0 metres two connectorpermanent link.

: The first value for each pair gives the worst case margin to limit from 1 MHz to3

250 MHz, while the value in brackets is the worst case margin to limit from250 MHz to 500 MHz.

It is concluded from table 5.2 and return loss recordings in pages 26 and 27 that return losscomplies with the specified Class E / Category 6A requirements in the complete frequency rangeA

from 1 MHz to 500 MHz seen from both ends of the permanent links.

5.3 Attenuation

Summarised results of testing are found in tables 5.3.1 and 5.3.2, and include all four tested pairsmeasured from one end of the permanent link. Table 5.3.1 presents measured values at specificselected key frequencies while table 5.3.2 gives the worst case margin to limit (in pct.).Recordings of attenuation versus frequency are found in page 28 of the appendix.

Tables 5.3.1 and 5.3.2, and the attenuation recordings in page 28 are making reference to theattenuation limits at the nominal temperature of 20,0°C. The actually applied test temperature was22,0°C. The degradation of attenuation with temperature of screened cables is in internationalstandards specified to be max. 0,2 %/°C between 20°C and 60°C. Only small variations intemperature dependence of screened cable attenuation exists on the market and it is thereforegenerally not necessary to seek product specific information about temperature dependence of theattenuation from the screened cable supplier.

of 47


If the specified values are assumed to apply for the cable of the presently tested permanent linkthen no cabling design modification is necessary below 68°C. This means at 60°C, for instance,that no reduction of the totally allowed maximum horizontal cable length is required to avoidtemperature problems for an installation using the tested permanent link (with reservation foractual temperature performance of attenuation).

5.7 Power Sum Alien Near End Crosstalk (PSANEXT)

Alien near end crosstalk performance is concluded to pass requirements based on measurementof coupling attenuation. It is specified in edition 2.2 of ISO/IEC 11801 that alien crosstalkperformance of screened cabling will always comply with the requirements and needs not betested when EMC performance is better than 50 dB (100 MHz coupling attenuation value). EMCperformance was 57 dB, which passes the 50 dB limit requirements for alien crosstalkmeasurements.

Consequently, measurements of alien near end crosstalk have not been carried out.

5.8 Power Sum Alien Equal Level Far End Crosstalk (PSAACR-F)

Alien far end crosstalk performance is concluded to pass requirements based on measurement ofcoupling attenuation. It is specified in edition 2.2 of ISO/IEC 11801 that alien crosstalkperformance of screened cabling will always comply with the requirements and needs not betested when EMC performance is better than 50 dB (100 MHz coupling attenuation value). EMCperformance was 57 dB, which passes the 50 dB limit requirements for alien crosstalkmeasurements.

Consequently, measurements of alien far end crosstalk have not been carried out.

5.9 DC Loop Resistance

Results of testing are found in table 5.9, and include all four tested pairs measured from one endof the permanent link.

Measurement of DC loop resistance is carried out at room ambient temperature and results areequalled to 20°C by calculation. A degradation of DC loop resistance with temperature mustalways be accommodated for by the design of the installation, for instance by making a total cablelength reduction taking into account the temperature effects on the DC loop resistance at thehighest temperature for which the installation is intended to run. The worst case temperatureeffect can be expected to be 0,4 %/°C.

For the permanent link in question no cabling design modification will in reality be required fromtemperature degradation of DC loop resistance due to its very large headroom to the limit.Potential design reduction imposed by temperature degradation of attenuation is discussed inclause 5.3.

6. CONCLUSION

Electrical transmission performance testing of Telebox two connector permanent link consistingof






has in every respect shown compliance with the screened Class E / Category 6A requirements.A

Furthermore, the performance of a short, simularly configured two connector permanent linkcontaining 30,0 metres of horizontal cable between wall outlet and patch panel instead of90,0 metres has also been measured and compliance with requirements has been concluded. Thisadditional testing concerns the critical noise parameters of return loss, and pair-pair and powersum near end crosstalk.

Testing was conducted using the patch panel, P/N MLB246ASx. The patch panel,P/N LB246ASx, is also covered by the positive conclusion of testing. The two types of patchpanels are having the same printed circuit board design and both pass the transfer impedancerequirements.

The electrical performance of the horizontal cable, keystone jack and patch panels has beenmanufacturer verified.


of 47


A 3P qualification is therefore granted for the Telebox two connector permanent link,consisting of a combination of the following horizontal cable, connecting hardware and RJ 45plug:

• Individual Foil and Overall Braid ScreenedHorizontal Cable from Draka, Type Silverline Gold 1000

• Screened Keystone Jack from Telebox, P/N TB806ASxhaving PCB Marking 001-8074

• Screened Patch Panels from Telebox, P/N MLB246ASxandP/N LB246ASxhaving PCB Marking Cat.6A 001-0895

• Screened RJ 45 Plug from Telebox, P/N TA3368DS

for screened Class E / Category 6A installations.A

Qualification of the Telebox two connector permanent link for screened Class E / Category 6AA

installations will be valid until failure to pass one of the maintenance of qualification testprogrammes, which will be performed at 12 months intervals. Also, the qualification is made onthe premise that all keystone jack, patch panels, horizontal cable and RJ 45 plug have andmaintain quality and performance levels corresponding to the ones of the components of thepresently tested permanent link, are correctly terminated according to the Telebox instructions,and are installed using proper workmanship in compliance with all specified and relevantinstallation guidelines.
