This letter describes an efficient and economical method for dropping optical fiber to residential premises in which several fiber ribbons in a distribution cable are assigned to one dropping point. The optical fiber cables for dropping, which contain mono-coated fibers, are then aerially installed between several poles from this point during initial construction. One or two fibers in a cable are then branched and dropped to a subscriber when the demand arises. When an optical drop wire stranded cable is used as the optical fiber cable for dropping, the above method can be employed without the need for a fiber joint in the dropping portion. The tube stranding pitch of this cable is investigated theoretically and experimentally, and the cable is manufactured based on the results. The transmission characteristics of the cable are confirmed to be stable.
