Fiber Cable Procurement Length Calculator

Estimate cable reel length from route distance, percentage slack, and explicit slack reserved at splice locations.

Inputs

Link inputs

Range: 0–1,000,000 m

Use the actual duct or aerial route length.

Range: 0–20 %

FOA describes 2% as typical in its cited OSP guide; adjust this project input to the route and owner standard.

Range: 0–10,000

Count closures where reserve cable is required.

Range: 0–100 m

FOA describes 17 m as a traditional handhole/manhole reserve (15 m slack + 2 m splicing); use the project requirement.
