Unitary fan-out device for optical ribbon cables

The present invention generally relates to optical fiber closures and, more particularly, to an optical fiber closure having improved optical fiber capacity and insertion loss characteristics. Optical ribbon cable fan-out device includes a top cover portion, a fan-out portion and a bottom portion formed as a unitary body. The fan-out portion has an array of guides housing individual fibers of the optical ribbon cable. The top cover portion and bottom cover portion are connected respectively to the fan-out portion by first and second hinges. The top cover portion and the bottom cover portion each have a plate projecting respectively therefrom to secure a ribbon cable in an axis extending longitudinally through the fan-out apparatus. The fan-out portion is so configured that a first portion of the arrayed guides is co-linear with the axis, a second portion of the arrayed guides is above the axis and a third of the arrayed guides is below the axis. The fan-out apparatus defines pathways for individual optical fibers having a bend radius of at least approximately 1.5 inches.
