All cables and termination hardware shall be 100% tested for defects in installation and to verify cabling system performance under installed conditions according to the requirements of ANSI/TIA 1152, ANSI/TIA-568 C.2 and IS&T. All pairs of each installed cable shall be verified prior to system acceptance. Any defect in the cabling system installation including but not limited to cable, connectors, feed through couplers, patch panels, and connector blocks shall be repaired or replaced in order to ensure 100% usable conductors in all cables installed.
Copper Channel Testing
All twisted-pair copper cable links shall be tested for compliance to the requirements in ANSI/TIA 1152 and ANSI/TIA 568-C.2 11 for the appropriate Category of cabling installed. All wire harness cabling shall be tested with a Link-Runner test meter. Testing for basic network connectivity is required. Reports to be generated and delivered to client representative.
Fiber Optic Testing
All installed fiber shall be tested in accordance with ANSI/TIA-C.0 AND ANSI/TIA-3.3. For horizontal cabling system using multimode optical fiber, attenuation shall be measured in one direction at either 850 nanometer (nm) or 1300 nm using an LED light source and power meter. Backbone multimode fiber cabling shall be tested at both 850 nm and 1300 nm (or 1310 and 1550 nm for single mode) in both directions. Single mode testing shall incorporate the same testing methods as Multimode for the proper spectrum. Test set-up and performance shall be conducted in accordance with ANSI/568-C.0 Standard, Method B. Where links are combined to complete a circuit between devices, the Contractor shall test each link from end to end to ensure the performance of the system. ONLY PERMANENT LINK LOSS TEST IS REQUIRED. The contractor can optionally install patch cords to complete the circuit and then test the entire channel. The test method shall be the same used for the test described above. The values for calculating loss shall be those defined in the ANSI/TIA 568-C.3 Standard.
Attenuation testing shall be performed with a stable launch condition using two meter jumpers to attach the test equipment to the cable plant. The light source shall be left in place after calibration and the power meter moved to the far end to take measurements.
