A technique for storing cable slack in an automatic and safe manner, to allow a plug and play connectivity for fiber optic cable installation between floors in multi-floor high-rise apartment buildings. A tamper-proof storage box is located in a prescribed location for which its footprint is intended, such as a utility closet in a lobby or basement. The box contains a number of reels of cable (bundles of individual optical strands), each reel's contents designated for a different floor in the building. As pre-connectorized strands are pulled from a rotatable spindle mounted in the storage box to its intended floor, any cable excess (slack) remains automatically on the spindle in the storage box in an out-of-the-way location avoiding tampering and tripping. This allows off the shelf lengths of cable saving time and expense.
