A predetermined optical fiber cable has a main trunk cable comprising a plurality of optical fibers disposed therein and multiple drop cables spliced to the trunk cable at various branch points, the preterminated fiber optic cable being completely assembled at the time of manufacture and is easily installed thereafter. At each branch point an optical fiber cable splice closure is utilized for protecting the optical fibers and splices from moisture and mechanical damage, providing a strong anchoring point for the optical fiber drop cable, and insuring that the minimum fiber bend radius is not violated. The splice closure is cylindrical in shape and has a cavity providing room for the splices and for excess optical fiber storage. Because the splice closure is relatively small (an outer diameter of no greater than 4 inches and a length of no greater than 7 inches), the preterminated fiber optic cable, after manufacture, may be wound in reels for installment without incurring cable or fiber damage and, further, may be depolyed within standard PVC piping having a 4 inch inner diameter. The preterminated fiber optic cable may also be preconnectorized.
