Abstract: An optical fiber connector (11) that is tunable despite being fully assembled has a assembly having an enlarged ferrule (24,27) holding member or flange (26) that has a multi-faceted, hexagonal periphery (33), and a tapered portion with slots. The connector has a front housing portion (12) that has a multi-faceted seating region for the flange. The flange is disengageable from the seating region for tuning rotation by being movable axially toward the rear of the housing (13) against the force of a spring (29). The connector can be tuned by incremental rotations of the assembly when the flange is disengaged. The tuning which is executed with a tuning wrench engaged in the slots, reduces coupling loss by rotation of the eccentricity vector. The optimum position can be determined by using a tuning tool and coupling loss measurements.
