A spool for a telecommunications cable. The spool winds-up and pays-out the cable without accumulating twist in the cable. The spool 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 is winding-up or paying-out. The spool includes a base, a cable wrap reverser, and a hub. The spool is adapted to wrap the cable about the base in a first wrapping direction and is adapted to wrap the cable about the hub in an opposite second wrapping direction. The cable wrap reverser is adapted to transition and guide the cable from the first to the second wrapping direction.
