CABLING SYSTEM CERTIFICATION TESTING
2
TWISTED-PAIR CABLING TESTING
3
Test Configurations Certification testing may be performed for either of two or both models of the cabling system: –Channel –Permanent Link
4
Channel Model The Channel test configuration should be used to verify the overall Channel performance Channel starts here ABCDE FIELD TESTER TRWA TOCPHC Channel starts here
5
Channel Model 1 Any Channel models of the twisted-pair Horizontal and Backbone subsystems with the cable overall length of under 100 m, including connecting hardware and equipment cords, shall pass 100% certification testing The Channel certification testing of the twisted-pair Signamax Cabling System may apply the testing settings of the field testers for the compliance of the cabling system Channel transmission performance parameters with the requirements of various standards (ISO, TIA, CENELEC, AS/NZ and any others available in the field tester software)
6
Permanent Link Model The Permanent Link test configuration should be used to verify the efficiency of permanently installed cabling Link starts here ABCD FIELD TESTER TRWA TOCPHC Link starts here
7
Permanent Link Model 3 Any Permanent Link models of the twisted-pair Horizontal and Backbone subsystems with the cable length of less than 90 m (295 ft) shall pass 100% certification testing The Permanent Link certification testing of the twisted- pair Signamax Cabling System may apply the testing settings of the field testers for the compliance of the cabling system Channel transmission performance parameters with the requirements of various standards (ISO, TIA, CENELEC, AS/NZ and any others available in the field tester software)

TEST PARAMETERS
9
Test Parameters 5 On testing of the category 5e, 6, and 6A Channels and Permanent Links of the twisted-pair cabling system the following parameters shall be tested: Wire map and screen continuity Return loss (RL) Insertion loss (IL) Propagation delay (PD) Propagation delay skew (PDS) Pair-to-pair near-end crosstalk loss (NEXT) Power-sum near-end crosstalk loss (PSNEXT) Pair-to-pair attenuation-to-crosstalk ratio, far end (ACRF) Power-sum attenuation-to-crosstalk ratio, far end (PSACRF)
10
Test Parameters 1 On testing of the category 6A Channels and Permanent Links of the twisted-pair cabling system the following parameters are recommended to be tested, but not required for the Signamax Cabling System warranty provision: Power-sum alien near-end crosstalk (PSANEXT) loss Average power-sum alien near-end crosstalk (PSANEXT) loss Power-sum attenuation-to-alien crosstalk ratio, far-end (PSAACRF) Average power-sum attenuation-to-alien crosstalk ratio, far-end (PSAACRF)
11
TEST RESULTS
12
PASS/FAIL Criteria A Pass or Fail result for each parameter shall be determined by the permissible parameter limits The parameter test result shall be marked with an asterisk (*) when it is closer to the test limit than the measurement accuracy published by the field tester manufacturer for the Permanent Link and Channel
13
PASS/FAIL Criteria 1 – Parameter allowable limit 2 – Measurement accuracy upper limit 3 – Measured parameter value 4 – Measurement accuracy lower limit 12341234
14
PASS/FAIL Criteria 6 The test results marked PASS obtained as a result of testing of all the parameters determined in 5 shall be registered and submitted for the warranty provision. The test results marked PASS*, FAIL* and FAIL shall not be registered and submitted for the warranty provision
15
Test Results Saving 7 Any positive test results shall be recorded in an electronic format with software supplied by the field tester manufacturer. The test results supplied in the format not supported by the field tester software shall not be accepted for registration
16
FIELD TESTERS
17
Qualified Field Testers 8 Warranty certification testing of transmission performance of the Signamax Cabling Systems shall be performed by one or several of the following field testers : –Agilent Technologies:WireScope 350, WireScope Pro, FrameScope 350 –Fluke Networks:OMNIScanner, OMNIScanner2, DSP-4000, DSP-4100, DSP-4300, DTX-1800, DTX-1200, DTX-LT –IDEAL Industries:LT 8100A, LT 8155T, LT 8600T, LANTEK 6, LANTEK 7, LANTEK 7G, LanTEK II-350, LanTEK II-500, LanTEK II-1000 –JDSU:Certifier40G –Megger:SCT1500, SCT2000 –Psiber Data:WireXpert
18
Software 9 Qualified field tester used for the Signamax Cabling System testing shall operate with the latest software version as of the date of such testing. Test results obtained with outdated software version are invalid and shall not be accepted for the system warranty registration.

OPTICAL FIBER CABLING TESTING
20
TEST CONFIGURATIONS
21
Optical Fiber Link An optical fiber link segment is the passive cabling, to include cable, connectors, and splices (if present), between two optical fiber connecting hardware termination points TEST JUMPER 1 OPTICAL FIBER LINK UNDER TESTTEST JUMPER 2 CROSS-CONNECT OR OUTLET LIGHT SOURCEPOWER METER 850 nm1300 nm ONOF -14.3 dBm 850 nm 1300 nm ONOF CROSS-CONNECT
22
TEST PARAMETERS
23
Test Parameters Testing of the optical fiber components and systems includes measurements of several major characteristics For the certification testing of the majority of the optical fiber cabling systems, installed in the buildings and campus environments, it is usually sufficient to get the data on insertion loss and, optionally, return loss and optical length Bandwidth (multimode) and dispersion (singlemode) are important performance parameters, however as they cannot be adversely affected by installation practices, they should be tested by the fiber manufacturer and do not require any field testing
24
Insertion Loss 15 Any optical fiber Links of the Horizontal and Backbone cabling subsystems shall be tested for insertion loss Insertion loss test shall be carried out by the one reference jumper method
25
FIELD TESTERS
26
Qualified Field Testers 20 Warranty certification insertion loss testing of the Signamax Optical Fiber Cabling System shall be performed with: –Power meter and light source or –Test equipment listed in 6, including the optical fiber detectors within their sets, facilitating insertion loss tests Characteristics of the test equipment shall comply with the specifications given in sections “12.2.6.4 Power meters” and “12.2.6.5 Light sources” of the Signamax Cabling System Manual
