VOICE & DATA COMMUNICATIONS Section 16760 15-1207 change requiring a re -submittal. The scope of this work includes, but is not limited to, the following: 1. Check all system(s) for compliance with the Owner Standards and Specifications 2. Maintain a check -off list for reference by the Owner during tests. 3. The result of the measurements outlined shall be recorded and submitted to the Owner as final proof of system performance. 4. All systems must pass specifications and be accepted by the Owner before the work shall be considered complete 5. All cables will be tested with a tester and assigned its number with auto test. All outlets will be tested for shorts, crosses, transpositions, reversals, opens, grounds, foreign battery, continuity, and resistance (in ohms). 6. Test Report Formats: Test results will be reported as follows: Jack Short Open Trans Rev Cross Grd Bat Cont Res 1.3/0005/D No No NoNo No No No Yes 45.6 1.3/0005/D No No NoNo No No No Yes 45.7 All horizontal wiring/information outlets (100%) will be tested (in dB) on the 10GBase-T segment for Worst Pair to Pair Near -End Cross -Talk (NEXT) and Attenuation at the following frequencies: .772 MHz, 1 MHz, 4 MHz, 8 MHz, 10 MHz, 16 MHz, 20 MHz, 25MHz, 31.25 MHz, 62.5 MHz, 100 MHz, 155 MHz, 200 MHz, 250 MHz, 300 MHz, 350 MHz, 400 MHz, 500 MHz, 550 MHz, 600 MHz, 650 MHz, 750 MHz. The results will be reported to meeting the Manufacturer's published specification for Attenuation, Pair to Pair and NEXT. C. Pairs not meeting the requirements of the standards will be brought into compliance by the Contractor at no charge to the Owner. Complete end-to-end test results must be submitted to the Owner before acceptance sign -off. 3.7 FIBER TESTING: All fiber testing shall be performed on all fibers in the completed end-to-end system. There shall be no splices allowed in the fiber cabling. Testing shall consist of a bi- directional end to end OTDR trace performed per TIA 455-78 or a bi-directional end to end power meter test performed per ANSI/TIA-EIA-5688.1. The system loss measurements shall be provided at 850 and 1310 nm for single -mode fibers. A. All fiber supplied to the Owner must be tested before installation, while still on the shipping reel. The test results must be compared to the manufacturer's test results. A discrepancy of more than 1 dB on any fiber in either window indicates possible shipping damage and the fiber must be returned to the supplier. The test results must be maintained in a file for future reference. The Contractor is responsible for insuring fiber integrity and performance specifications. B. All fibers must be tested after installation according to the procedures and acceptability criteria as described in the pre -installation testing. The results of these tests (printed results and tabular loss results) must be provided by the Contractor as documentation of the quality of installation and as a baseline for future troubleshooting. The results must be compared to the pre -installation test results for significant changes. All optical test equipment must have current, traceable calibration certification. C. Fiber links shall have a maximum loss calculated as: (allowable cable loss per km)(km of fiber in link) + (.4dB)(number of connectors) = maximum allowable loss A mated connector to connector 13
