Abstract
An optical cable formed by optical fibers, a forming pipe, a sheath, a pair of tension members, and a pair of rip cords. The forming pipe includes a plurality of tapes arranged to permit the forming pipe to be divided in the longitudinal direction and the rip cords are located near the seams of the forming pipe. A distance from the surface of the tension members to the inner surface of the sheath and to the outer surface of the sheath are both 0.3 mm or more. A distance from the center of the rip cords to the inner surface of the sheath is from 0.2-fold or greater to 1.2-fold or less than the radius of the tip cords. Furthermore, the distance from the surface of the rip cords to the seams of the forming pipes is 0.5 mm or less.
