Abstract

PURPOSE: To form such a gas dam which is flexible and does not cause degradation of optical fiber characteristics by inserting the pipe having plural holes intermittently into a cable and injecting tacky resins with this pipe as a passage.
CONSTITUTION: One or a plurality of pipes 6 opened intermittently with holes 61 are inserted into the sheath 5 of the optical fiber cable and tacky silicone resin or the like is injected into the cable containing optical fiber cores 2, from one end of the pipes 6 and is emitted from the holes 61, whereby the resin 7 is packed intermittently. In this way, the cable has flexibility and is prevented of the degradation of the optical fibers 2 owing to the stress.
