How Do You Measure Fiber Optic Cable Length?
Fiber optic cable length measurement depends on the context and desired precision. Several methods exist, ranging from simple approximations to highly accurate techniques used in

The round trip time that the light takes to travel through both fibers is converted to length in kilometers, then divided by two to show the length of the fiber cable. These pulses travel down the fibre and reflect when they encounter inconsistencies, like breaks, splices, or bends. Fiber Length calculator uses Length of Fiber = Group Velocity*Group Delay to calculate the Length of Fiber, The Fiber Length formula is defined as the length of fiber cable that is being used to propagate the signal. This Applications Engineering Note (AE Note) addresses estimating cable length or event distance using an optical time domain reflectometer (OTDR). Reel count is ceil (Total ÷ ReelSize), and the rounded order length equals Reels × ReelSize. Intended for short laboratory-bench runs, is typically sold with the lab NIR-O analyzer. This more flexible NIR fiber can be supplied in PVC-coated steel monocoil jacket, steel armored BX jacket, or PVC-zip tubing.
