How many kilometers is a standard optical cable reel
Fiber cable is normally shipped with a maximum reel length of 15,000 feet (or 4. Assume that this system will have at least 4 mid-span fusion splices. Table 11-2: Fiber Loss Budget CalculationCorning, OFS, and Prysmian all offer 20,000-foot reels for loose-tube cables in this fiber count range. Some will go to 25,000 feet on request for 12F, though you'll pay a premium for the larger reel and may face delivery logistics headaches if the staging area is tight. Applied for aerial installation on distribution and power transmission lines for building long distance optical. Fiber optic reels are manufactured in wood, metal, or heavy-duty plastic, and are defined by three primary dimensions: flange diameter, traverse (barrel) width, and core diameter. 5/km so your 25km link I'd expect a loss around 12-15db loss. org/tech/ref/Loss_Budget/Loss_Budget. htm I usually assume 4-5 splices per 40000feet As others have said, the length of the spool is typically not your limiting factor. ts must be converted to kilometers. In fact, the total margin is 8.
