Network Cable Maximum Lengths: Ethernet, Coaxial, and Fiber Optic
In the design of any network—whether a home Wi-Fi setup, an office backbone, or a global telecom infrastructure—the maximum length of network cables is a make-or-break factor.

Cable knowledge
Depending on the cable structure, this excess length is 0.5 to 1.5 %. The overlength protects the fiber in the event of bending stress or tension on the cable. With both loads, the cable expands locally

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

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%.
