A furcation system of an optical fiber assembly includes a fan-out and a transition tube. The fan-out includes a surface and stations. The surface is flexible such that the surface is configured to be changed from flat to curved. The stations are coupled to one side of the surface and are configured to receive and hold sub-units of an optical fiber cable, while allowing the sub-units to project from the stations. The stations are spaced apart from one another such that the stations provide separation between the sub-units received by the stations. Bending of the surface moves the stations from a planar arrangement to a three-dimensional arrangement such that the sub-units may project from the stations of the fan-out in planar and three-dimensional arrays.
