摘要： The present invention's optical cable is provided with optical fibers, a forming pipe for housing the optical fibers, a sheath provided around the forming pipe, and at least one pair of rip cords embedded in the sheath. The forming pipe is formed of a plurality of tapes so that it is dividable along its longitudinal direction. When dividing the optical cable, the rip cords are pulled to tear open the sheath, and the already split forming pipe is divided while staying adhered to the respective parts of the sheath. As a result, the division of the sheath and the forming pipe is carried out in one stroke, so that the optical fibers inside the forming pipe can be exposed easily and quickly.
