    Abstract: A tuning index tool for use in determining the degree of tuning necessary fo r a tunable optical fiber connector has a first stationary member having a connector adapter affixed thereto and a second movable member within the first member and spri ng loaded with respect thereto. The second member has a connector adapter affixed thereto axially aligned with the adapter in the first member. The movable member is incrementally rotatable with respect to the stationary member by being pulled against the spring force to disengage the ferrules of connectors in the adapters, which are aligned i n a split sleeve. rotation changes the orientation of the eccentricity vectors of the two connectors, and hence the insertion loss. Measurements of insertion loss are made, and the orientation of the connectors for minimum loss is noted. The number of incremental rotations of the tool indicates the incremental rotation of the ferrule of t he connector under test, the eccentricity vector orientation of the other connector being known, that is necessary to achieve minimum insertion loss for the connector with connector s have a known eccentricity vector orientation.

    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.

    Abstract: A plug type connector is adapted to be latched to a backplane wall in a fixed position and has a tapered front, noses or connector end for insertion into an adapter which plugs into the backplane wall. The adapter may be misaligned in any or all of the X, Y, Z axes. The tapered nose cams the X or Y misaligned adapter into axial alignment as the adapter and its mount are being inserted. A shortened front or connector end of the connector causes the ferrule of the connector to project beyond the optical plane of the connection so that it reaches a ferrule in a Z aligned adapter to complete the connection. A coil spring within the housing of the connector is tuned to allow counter movement of the ferrule where the ferrule in the adapter is too long, thereby shifting the position of the optical plane. The connector has a ferrule-barrel assembly within a housing and an insert member which has an enlarged diameter portion which is contained by openings in the housing to prevent rotation of the ferrule-barrel assembly

    Abstract: A tunable adapter for joining optical fiber connectors with other elements has a housing (12) in which are contained a fixed disc member (28) having a connector receiving jack (19) mounted thereon, the axis of which is surrounded by an array of indexing member (41). The housing further contains a movable wall member (17) having a connector jack (19) extending therefrom, the axis of which is surrounded by an array of indexing members (37) adapted to mate with the indexing members on the fixed disc member. The movable wall is biased toward the disc member by means of a spring member (36) so that, in normal operation, the indexing members are mated. When the movable wall is pulled out of engagement, it is rotatable so that the adapter may be tuned by an approximate alignment of the eccentricity vectors of the two connectors.
