What is recommended to have for future changes and restorations?

• A. Slack (service loops)
• B. Spare splices
• C. Extra duct plugs
• D. Additional fiber

Answer: (A)

Having slack in the fiber run, as service loops, is the practical way to plan for future changes and restorations. Service loops are extra lengths of fiber tucked into splice closures or terminations so you can re-terminate or reroute without pulling new fiber from the trunk. This setup speeds up restoration after a fault and makes it easier to add new branches or upgrade equipment later, because you already have usable length available without digging up and replacing the main route. Spare splices don’t provide that extra length to reconfigure an existing path, and extra duct plugs or simply adding more fiber don’t directly enable changes or quicker restoration in the same way.
