What range of slack fiber length is considered useful?

Slack fiber length is the extra length left in a run so you can accommodate future changes, repairs, or provisioning without pulling new fiber. Six to thirty meters provides a practical balance: there’s enough room to perform splices, reroute, or extend the fiber at pull points or handholes, and to absorb small movements or thermal expansion, while still keeping the slack manageable and within safe bend radii. If slack is only a few meters, you may not have enough length for field adjustments or replacements. If slack is much longer, it becomes difficult to manage, increases the chance of damage from movement or handling, and adds unused fiber that can collect dust or moisture. So, six to thirty meters is the useful range.
