Abstract
In an optical fiber ferrule assembly, a bare optical fiber, an end coating of which is removed, is inserted and fixed into the central hole of a ferrule body. By setting the distance between a boundary point at which the bare optical fiber is fixed at the rear end of the ferrule body and a next point at which the bare optical fiber is fixed to a fixing member which is formed integrally with the ferrule body via a coating of an optical fiber core to the range of 0.5 to 6 mm, more preferably, to the range of 1 to 4 mm, stress concentration at the boundary point at which the bare optical fiber is bonded and the point at which the optical fiber core is fixed cab be reduced.
