Abstract: Provided is a field assembly optical connector comprising: a first unit which includes a housing, a frame provided within the housing, and a fixing member installed in the frame; a ferrule unit which has a portion inserted into the fixing member and into which a core of an optical fiber is inserted; an optical fiber fastening means which is installed in an end of the ferrule unit and pressurizes an outer face of the optical fiber having the core inserted into the ferrule unit to fasten the optical fiber; and a second unit which is coupled to the fixing member and fixes positions of the ferrule unit and the optical fiber fastening means. According to the field assembly optical connector, since an outer face of an optical fiber led in an optical connector is directly fixed by a collet unit including a plurality of groups, splicing of the optical fiber can be strengthened, and the optical fiber can be prevented from being affected by the horizontal external force. Furthermore, since an optical connector assembling work is simplified and accurate core alignment is accomplished, loss of light occurring during core splicing can be prevented.
