A method of reinforcing a multiple optical fiber coupling unit is provided including the steps of removing a portion of longitudinal coatings of optical fibers of the multiple optical fiber coupling unit to expose glass portions of said optical fibers; fusing a portion of the exposed glass portions so as to optically couple the optical fibers; extending the fused portion to a predetermined state; fixing non-extended portions of the exposed glass portions on a first reinforcing substrate with a first adhesive; and fixing the first reinforcing substrate on a second reinforcing substrate with a second adhesive. The multiple optical fiber unit coupler made by this method has a transmission characteristic that does not substantially change even with a temperature change and under high humidity.
