Abstract: Multi-fiber, fiber optic cable assemblies and related fiber optic components, cables, and methods providing constrained optical fibers within an optical fiber sub-unit are disclosed. The optical fiber sub-unit(s) comprises optical fibers disposed adjacent a sub-unit strength member(s) within a sub-unit jacket. Movement of optical fibers within a sub-unit jacket can be constrained. In this manner, the optical fibers in an optical fiber sub-unit can be held together within the optical fiber sub-unit as a unit. As a non-limiting example, the optical fiber sub-unit(s) may be exposed and constrained in a furcation assembly as opposed to the optical fibers, thereby reducing complexity in fiber optic cable assembly preparations. Constraining the optical fibers may also allow optical skew, reduction of entanglement between the optical fibers and the cable strength members to reduce or avoid optical attenuation, and/or allow the optical fibers to act as anti-buckling components within the fiber optic cable.

Abstract: Embodiments disclosed herein include ferrule assembly having a ferrule and a ferrule boot that is coupled to the ferrule. The ferrule boot is used for aligning an array of optical fibers in the desired arrangement when entering the ferrule. In one embodiment, the ferrule boot may have a two-piece construction that includes a fiber alignment portion that defines a first groove for a first row of optical fibers and a cover portion. Moreover, the ferrule boot may be configured to accommodate multiple rows of optical fibers. Other embodiments may use a bendable material for the ferrule boot and/or include color coding for aiding the craft with fiber positioning.

Abstract: An exemplary apparatus includes ferrule offset assemblies each having opposing ferrules with respective ends and respective fiber channels maintained in general relative and adjustable alignment. Offset adjusting devices adjust the relative alignment of the fiber channels to create at least one select fiber channel alignment offset. Respective multimode fibers are disposed in the fiber channels and have a fiber alignment corresponding to the fiber channel alignment. One of the multimode fibers has an end configured to optically couple to a launch multimode fiber, which is connected to a device having a light source. The multimode fiber receives light from the launch multimode fiber so that at least some of the light passes through to the other multimode fiber and then to a power meter. Power measurements for different fiber offsets are then compared to established attenuation values.
