The present invention relates to an optical fiber cable capable of recognizing a reversal section and a construction method according to the same. According to the present invention, a specific loose tube, which a user wants to use, can be separated from a reversal section without interference by marking a stripped zone on an outer cover corresponding to a reversal section between S-direction group and Z-direction group of unit comprising an optical fiber cable, applying an outer tape which makes a loose tube identified, and stripping the outer cover from the reversal section. Also, splicing of distribution and insertion cables can be possible at a point which requires a branching after fabrication of optical fiber cable or deployment of pipe by making a space enough for connection work by enabling separate extraction of specific optical fiber of the loose tube. To work within a narrow space cabinet or an optical fiber splice closure, the loose tube is formed with a flexible material, and an internal waterproof material is formed with waterproof thread to make extraction a specific optical fiber core which the user wants to use among the optical fiber cores in the loose tube possible. By applying an auxiliary strength member together with an internal strength member, the fixability of cable with various structures can be provided. |
