PART 3 – PRODUCTS

3.1 EQUIPMENT, MATERIALS AND WORKMANSHIP

A. General: It is the intent of these Contract Documents to secure high quality in all equipment and materials, and to require first class workmanship, in order to assure long, trouble-free operation and minimum maintenance of the installed components.

B. Equipment and materials shall be the products of reputable, experienced manufacturers with a verifiable history of manufacturing similar equipment. Similar items in the project shall be the products of the same manufacturer. All equipment shall be of industrial grade and standard construction, shall be of sturdy design and manufacture, and shall be capable of long, reliable, trouble-free service.

C. All work, including installation, calibration, testing, adjustment, start-up and maintenance, shall be done by qualified experienced personnel who are technically skilled in their trade, are thoroughly instructed, and are competently supervised. The resulting completed installation shall reflect professional quality work, employing the highest industrial standards and methods.

D. The fiber optic cable shall be installed without field splices. Cable shall be run continuously between connection centers. All conduit runs shall be installed as not to exceed the minimum bending radius of the fiber optic cable as defined by the cable manufacturer.

3.2 TESTING OF FIBER OPTIC CABLE INSTALLATION

A. Acceptance Testing: The Contractor shall perform post-installation fiber optic cable acceptance tests of all cable installed under this Contract. The Owner shall be notified a minimum of 5 days in advance so they may have the opportunity to witness the tests. The tests shall measure a total attenuation or loss for each fiber on each cable reel. Document results of physical inspections to identify any cable and reel damage conditions, less or more than the specified fibers in the cable, and any deviations from the manufacturers’ specifications.
B. A recording optical time domain refractometer (OTDR) shall be utilized to test for end-to- end continuity and attenuation of each optical fiber. The OTDR shall be equipped with an
850 nm light source for the multi mode fiber (MMF). The OTDR shall have an X-Y plotter to provide a hard copy record of each test measurement. The OTDR shall be equipped with sufficient internal masking to allow the entire cable section to be tested. This may be achieved by using an optical fiber pigtail of sufficient length to display the required cable section.

C. The OTDR shall be calibrated for the correct index of refraction to provide proper length measurement for the known length of reference fiber.

D. A transmission test shall be performed with the use of an 850 nm stabilized light source and 850 nm power meter. This test shall be conducted in both directions on each fiber of each cable.

3.3 INSTALLATION SERVICES

A. General: The Contractor shall install, test, and provide complete test reports for all network hardware and software furnished under these specifications.

B. Installation Coordination: The Contractor shall coordinate all installation and testing with the Owner. No site work shall be done without a minimum of three (3) working day's notice.
