A payout cassette for a cable, which extends between first and second ends, stores and pays-out the cable. The cassette includes a storage area and a transitioning area. The storage area stores a stored portion of the cable between first and second generally parallel cable constraining surfaces that are spaced a distance from each other. The distance is sufficiently large to allow a single cable thickness to slide between the cable constraining surfaces and is sufficiently small to prevent another cable thickness from crossing over the signal cable thickness within the storage area. Thus, the storage area includes a single cable layer and thereby keeps the cable from becoming tangled. The transitioning area is adapted to transition the cable from the stored portion within the storage area to a paid-out portion of the cable that is external to the storage area. The transitioning area is at least partially positioned within an interior of the storage area.
