OPTICAL-COUPLER REINFORCING MATERIAL AND OPTICAL-COUPLER REINFORCING METHOD

摘要

The invention provides an optical-coupler reinforcing member for fixing and reinforcing a fiber-coupler body and a method of performing the reinforcing. The reinforcing member includes heat-shrinkage tubes which are shrunk by heating, and a hollow protection pipe provided in the heatshrinkage tubes. Cylindrical heat-fusible adhesive members are provided on opposite ends of the protection pipe, and heating is made such that a fusing portion of an optical-fiber coupler body is inserted through the reinforcing member so that the heat-fusible adhesive members and the heatshrinkage tubes are shrunk by heating to thereby fix and reinforce the optical coupler body.
