6.2 All billing invoices submitted to the Owner shall contain the following documentation and information: a. Location (Owner's work center and complete address) where work was performed b. Owner -issued Purchase Order (PO) number c. Name of the IS&T Division representative generating the service request d. Contractor's trouble ticket number or T&M work sheet identification number e. Description of T&M work activity actually performed or a description of trouble clearance. A List of all material used to complete the work request or trouble AND a copy of receipt(s) from Contractor's supply source depicting actual cost of material provided to complete the work request. f. Job start date, end date and time g. Test results completed after installation as specified in Specifications, Section 7.2.5 h. The IS&T Division is required to validate the accuracy of all billing invoices before payment authorization can be made; therefore, billing invoices received which do not contain the required information will result in a delay in payment. Invoices which cannot be validated by the Owner shall not be paid. 7.0 PROJECT SPECIFICATION - TECHNICAL 7.1 This "overall" project, with its individual work requests, shall consist of, but is not limited to, the procurement, delivery, installation and testing, of fiber optic cables, fiber optic cable terminations and terminating equipment and hardware, etc. 7.2 TESTING REQUIREMENTS 7.2.1 The Contractor shall be required to perform tests on all fiber installed, to ensure operational and technical conformity. Dispersion, splice loss, and optical time domain tests shall be performed on all fiber optic cable installed. 7.2.2 Dispersion, splice loss, and optical time domain tests, shall be performed on all fiber optic cable installed. 7.2.3 Each reel of fiber optic cable provided by the Contractor shall be accompanied by the manufacturer's test data showing the conformance to the requirements described herein. The manufacturer's test data shall identify each fiber in each cable and list its factory tested attenuation in decibels per kilometer. This attenuation shall meet as a minimum, the attenuation requirements set forth in Table — Fiber Optic Cable Specifications (Section 7.5.2) included in this document. Ensure that each finished and installed fiber optic cable segment shall be traceable to the test date on file for each step in its manufacturing process. The Contractor shall provide the County five (5) calendar days advance notice of the date the cable will be ready for final testing so that County staff may be present at the tests if staff elects. 7.2.4 The Contractor shall test the fiber optic cable at the site storage area prior to installation. Test each optical fiber in the cable from one end and one wavelength with an OTDR compatible with wavelength and fiber type. Check for continuity, kinks, anomalies, and appropriate attenuation. Record each measurement with color, location and type of fiber measured. If the tested loss per kilometer exceeds the loss from the manufacturers test data, the County will reject the cable. An electronic and hard copy shall be provided to IS&T prior to the fiber optic cable being installed. 7.2.5 After installation (splicing and termination) is complete, and if specified, the Contractor shall test the optical fiber in the cable again for the loss characteristics. Perform a uni- directional test on all terminated fibers using the Optical Time Domain Reflectometer (OTDR). Single mode fiber that is a distance of five (5) miles or less shall be shot at a 1310nm wavelength. Single mode fiber that is greater than five (5) miles shall be shot at a 1550nm wavelength. Multi -mode fiber shall be tested at an 850nm wave length. Results of these tests shall be provided to IS&T in both a hard copy and electronic format for 22
