A variable fiber count optical fiber cable core is disclosed. The cable core is intended for use as a part of an optical fiber cable, the optical fiber cable having an elongate cylindrical core tube formed about a longitudinal axis, and within which the cable core is received. The cable core comprises a stac k of a plurality of variable fiber count optical fiber units formed about the longitudinal axis of the core tube, and housed therein. The stack of the optical fiber units will comprise at least a first optical fiber unit having a first predetermined number of fibers therein, and at least a second optical fiber unit having a second predetermined number of optical fibers therein, where the first and second predetermined numbers of optical fibers differ from one another within the stack of optical fiber units. So constructed, the number of optic al fibers within selected ones of the stack of optical fiber units will be vari ed dependent on the position of the selected ones of the optical fiber units within the stack of optical fiber units, and so that the stack of optical fiber uni ts takes on the approximate shape of a cylindrical cable core within the cable core tube. Each of the optical fiber units comprised a first predetermined number of optical fibers sub-units joined together, each of the optical fiber sub-units being comprised of a second predetermined number of optical fibers, where both the first and second predetermined numbers of sub-units and optical fibers, respectively, comprise integers.
