ム付光ケーブル。[Scope of Claim for Utility Model Registration] (1) A gas dam having a structure in which the inside of a cable in which optical fiber core wires are arranged is maintained with gas, and a resin for preventing gas leakage is injected into a casing connected to the terminal part of the cable. 1. An optical cable with a gas dam, characterized in that the optical cable includes isolation means between the resin injected into the casing and the casing to prevent direct bonding between the two. (2) In the device set forth in claim 1 of the utility model registration claim, a plastic material is inserted between the casing and the resin as an isolating means to prevent the resin injected into the casing from directly joining the casing. An optical cable with a gas dam equipped with a film. (3) In the device described in claim 1 of the utility model registration claim, a release agent is applied to the inner wall of the casing as an isolating means to prevent the resin injected into the casing from directly bonding with the casing. Optical cable with gas dam made of layers. (4) Utility Model Registration An optical cable with a gas dam according to any one of claims 1 to 3, in which an optical fiber core wire and a metal communication wire are arranged in a composite manner.
