  • Patent number: 9753232
    Abstract: Embodiments include a fiber organizer comprising an optical interface having a plurality of optical interface-side fiber positions arranged in a linear array, and a cable-side interface having at least two pluralities of cable-side fiber positions each arranged in a linear array. The at least two pluralities of cable-side fiber positions are not collinear with each other, and in some embodiments define a two-dimensional array. A plurality of optical fiber paths extend between the optical interface-side and the cable-side of the fiber organizer such that each optical fiber extends between one of the optical interface-side fiber positions and one of the cable-side fiber positions. Because the transition from a compact bundle of fibers to a linear array occurs within the fiber organizer residing within the plug connector rather than the boot assembly, the boot assembly can be made more compact and ergonomic.
