The test results shall include: MHz sweep tests, continuity, polarity checks, wire map, Attenuation, NEXT, PSNEXT, FEXT, PSFEXT, ELFEXT, PSELFEXT, ACR, PSACR, Return Loss, Delay Skew, and the installed length for Category 5E cables. 2. Cables not complying with EIA/TIA 568A Category 5E tests for 100 Mb rating shall be identified to the engineer for corrective action which may include replacement at no additional expense to the Owner TESTING OF FIBER OPTIC CABLE A. General: Each strand in fiber optic cables shall be tested for correctness of termination, overall transmission loss, and defects using an approved Optical Time Domain Reflectometer (OTDR) and a power meter. The Engineer shall be present during all tests. Notify the engineer one prior to testing. B. Testing Equipment: Tester shall be as manufactured by Hewlett Packard, Fluke, Microtest, Noyes or Wavetek. C. Multimode fiber Testing shall be I.A.W. TIA/EIA method B. System loss measurements (both calculated and measured) shall be provided at 850 and 1300 nanometers in both directions for multimode cables (1310 and 1550 nanometers for singlemode) for each strand. Per IEEE 802.3z, maximum fiber strand attenuation shall not exceed nm with a modal bandwidth STRUCTURED CABLING SYSTEM

19 of 160 Mhz-km and nm with a modal bandwidth of 500 Mhz-km. Test as follows: 1. Measure and record normalized fiber loss at operating wavelength in db/km. 2. Detect and record point faults or discontinuities. 3. Measure and record overall length of cable. B. Certification report shall be provided listing both the calculated and measure loss for each fiber optic circuit and submitted with he test results as called for above. Provide test results in IBM text format on 3 1/2" diskettes as well as (2) hard bound copies in 3-ring binders. Documentation of testing shall include: Wavelength, fiber type, fiber manufacturer and cable model number, cable manufacturers attenuation specifications, cable manufacturers bandwidth specifications, Measurement direction, Test equipment and serial numbers (with date of last calibration), date of each test, reference setup, Name of technician(s) performing testing. OTDR trace(s) shall be submitted with request for substantial completion. END OF SECTION STRUCTURED CABLING SYSTEM
