A spool system for a telecommunications cable. The spool system winds-up and pays-out the cable without accumulating twist in the cable. The spool system can also pay out a distal end of the cable and mount a proximal end of the cable. Because no twist is accumulated in the cable, the first end and/or the second end of the cable can remain connected while the spool system is winding-up or paying-out. The spool system includes a base, a cable unwrapper, and a hub. The cable unwrapper and the hub rotate in opposite directions from each other. A first cable wrapping area is provided on the base and a second cable wrapping area is provided on the hub.
