It depends on cable diameter, jacket weight, and reel capacity. Here's how it generally breaks down in practice: 12-fiber through 48-fiber cable — These are your feeder drops and shorter distribution runs. Direct Answer: Select each cable drum length according to the actual route section, installation method, splice plan, cable. Fiber optic cable reel length planning is one of those LLD details that gets treated like an afterthought — right up until a project manager calls asking why the splice count doubled from the estimate. Choose your unit and keep it consistent. Enter each route section as a segment length and quantity. Applied for aerial installation on distribution and power transmission lines for building long distance optical. I'm trying to understand how many splices I should expect (roughly) in a "typical" length of OSP fiber for a utility type pull (144 OS2, inside an innerduct for dozens of miles). I'm reading spools come in various lengths, and I get that, but if I have a 25km run, how long would those spools. The following formulas may be used to determine general guidelines for installing Corning Optical Communications' fiber optic cable; however, refer to the cable specification sheet for the listed minimum bend radius: NOTE: Corning® RocketRibbonTM extreme-density cable (1728- and 3456-fiber) exceeds.
