ABSTRACT:
To avoid change in the property of an optical fiber, an optical fiber cord 100 has a structure fabricated by exposing a portion of the optical fiber 1 located at one end of an optical fiber core 15 which comprises a cushion layer 2 provided over the outer side of the optical fiber 1 and a cladding 3 provided over the outer side of the cushion layer 2; protecting one end of the exposed portion of the optical fiber 1 adjacent to the end of the cushion layer 3 with a roll of low hardness resin 4; and bonding the exposed portion of the optical fiber 1 to the capillary 32 of a ferrule 30 by an adhesive 20 so that the one end of the optical fiber core 15 is fixed integral with the ferrule 30. The stress of thermal shrinkage of the adhesive 20 is attenuated by the action of the low hardness resin 4 thus hardly acting on the optical fiber 1. Accordingly, a change in the property of the optical fiber 1 such as mode shift can be avoided.
