Abstract
A fiber optic bundle is wound for inside payout and is provided with a housing, with flanges, which maintains compressive force on the windings, and the payout of optical fiber is controlled by a substantially cylindrical mandrel placed in the interior of the inside payout spool. The mandrel supports a small-diameter tube through which the optical fiber pays and places drag on the optical fiber. The drag placed on the optical fiber passing through the small-diameter tube may be increased by slightly bending the tube. The combination of mandrel and small-diameter tube combine to hold the fiber coils in place and supply a certain amount of payout tension on the optical fiber.
