City of Sunny Isles Beach |Request for Proposal No. 22-04-01 32 3.19 Outer Jacket The all-dielectric cables (no armoring) shall be sheathed with medium or high-density polyethylene. The minimum nominal jacket thickness shall be 1.4 mm. Jacketing material shall be applied directly over the tensile strength members and shall not adhere to the Aramid strength material. The polyethylene shall contain carbon black to provide ultra-violet light protection, and it shall not promote the growth of fungus. The jacket shall be free of holes, splits and blisters. The cable jacket shall contain no metal elements and shall be of a consistent thickness. The jacket or sheath shall be marked with the manufacturer's name, the words "Optical Cable", the number of fibers, fiber type, month and year of manufacture, and sequential measurement markings every meter. The actual length of the cable shall be within ±1 percent of the length marking. The marking shall be in a contrasting color to the cable jacket. The print height of the marking shall be approximately 2.5 mm and must be permanent and weatherproof. The cable shall contain at least one ripcord under the sheath for easy sheath removal. 3.20 Quality Assurance The manufacturer(s) of supplied optical cable, optical cable assemblies and hardware shall be TL 9000 registered. 3.21 Fiber Characteristics One hundred percent (100%) of the optical fibers shall meet or exceed the requirements contained in this specification. The cable shall be tested in accordance with TIA/EIA-455-3A (FOTP-3), "Procedure to Measure Temperature Cycling Effects on Optical Fiber, Optical Cable, and Other Passive Fiber-Optic Components." The average change in attenuation at extreme operational temperatures (-40°C to +70°C) will not exceed 0.05 dB/km at 1550 nm. The magnitude of the maximum attenuation change of each individual fiber will not be greater than 0.15 dB/km at 1550 nm. This figure includes an allowance of up to 0.05 dB/km for measurement repeatability. All fibers within the finished cable shall be composed primarily of silica and shall have a matched clad index of refraction profile as well as the physical and performance characteristics that shall meet the requirements in the following table:
