Claim 9:
10. A reinforcement method for an optical fiber connection part using the reinforcement sleeve according to claim 1, the method comprising:
fusion bonding optical fiber ribbons, the optical fiber ribbon comprising a plurality of optical fiber core wires that are disposed side by side and bonded at intervals in a longitudinal direction;
moving the reinforcement sleeve so as to cover a connection part between the optical fiber ribbons;
heating the heat-shrinkable tube and the heat-meltable member so as to shrink the heat-shrinkable tube and melt the heat-meltable member at the same time; and
cooling the plurality of the optical fiber core wires in a state in which the plurality of the optical fiber core wires are arranged along a curved surface of the tension member so that the tension member and the connection part of the plurality of the optical fiber core wires are unified as one body.
