The wrap shall be weather resistant and limit solar heating of the cable such that cable surface temperatures do not exceed 10 degrees C above ambient temperature under solar radiation loading of 1000 watts per square meter in still air. The wrap shall be labeled "Do Not Remove Wrap Until Cable Is Placed." This wrap may be omitted when lags or other mechanical reel protection devices are provided. 5. A copy of the manufacturer's pre-shipping OTDR test data for each strand on each reel shall be included as documentation shipped underneath the thermal wrap or lagging. Test data shall indicate reel number, strand ID (number and color), measured strand distance, wavelength tested, dB/Km loss measured, and manufacturers test personnel name/ signature certifying product meets purchase specifications. 6. A copy of each reel test documentation record shall also be included in a weatherproof envelope showing the above information and also including date of manufacture, cable characteristics, and other information. 3 7. Reels and or/ cable damaged prior to acceptance at City of Ft. Collins deliver site shall be returned and replaced at no cost to the City. 3.2. FIBER OPTIC CABLE REQUIREMENTS A.
