For municipal utilities, which are increasingly building and operating their own fiber optic infrastructures, the professional implementation of OTDR
Estimating Cable Length with OTDR
In most outside plant cables (and some indoor cables), fiber length exceeds cable length. In stranded loose tube designs, this excess fiber length (EFL) is typically 2-3%.
The FOA Reference For Fiber Optics
Just measure the fiber on the spool of cable with the OTDR, then look at the cable jacket for length markings to get the actual length of the cable from the printed markings at each end of the cable.
The FOA Reference For Fiber Optics
Since fiber optic cable has about 1% excess fiber, the actual cable length is less than the fiber by that amount. The OTDR makes its measurements on the fiber, not the cable, so one must estimate the

Why OTDR and Optical Cable Jacket Length Markings Don''t Agree
While many of these cables are still being made and the excess length of fiber over jacket length is a function of the diameter of the core (larger core/bigger helix), there are now a
