Abstract: PROBLEM TO BE SOLVED: To provide an optical fiber connector adjustable even after being completely assembled. SOLUTION: A connector 11 is provided with the assembly having the member or flange which has the peripheral edge with many cut surfaces, whose shape is preferably a hexagon and which holds an enlarged ferrule 27. The connector 11 is provided with the forward housing part having an attaching area with many cut surfaces for the flange 26. The flange 26 can be separated from the attaching area for the rotation for adjustment because of being movable in the axial direction toward the back side of the housing against force of a spring. The connector 11 is adjustable by the increased rotation of the assembly when the flange 26 is separated.

Abstract: PROBLEM TO BE SOLVED: To obtain an adjustment index tool used for deciding the degree of adjustment required for an adjustable optical fiber connector. SOLUTION: This adjustment index tool 51 is provided with a first fixing member, and the first fixing member is provided with a connector adapter 61 stuck to the first member, a second movable member within the first member and a spring loaded relating to the first member. The connector adapter 63 of a second member is aligned in the axial direction with the adapter within the first member. The movable member is increasingly rotated with respect to the fixing member by being pulled against the force of the spring in order to separate the ferrule of the connector within the adapter. The adapter is aligned within a split sleeve. An insertion loss is changed because of the rotation in the direction of an eccentric vector with respect to two connectors.

Abstract: PROBLEM TO BE SOLVED: To realize connection with less optical loss by tunning with a connector, in the case of inconsistency on the X, Y and Z axes in a connecting adaptor, in an optical fiber connector to be connected to a back plane/wall. SOLUTION: With the connector end tapered, the inconsistency on the X and Y axes is corrected. Also, by shortening the tip end part, a ferrule is projected beyond the optical plane, dealing with the inconsistency on the Z axis. Further, by attaching a spring part, a ferrule length inside the adaptor is adjustable. Furthermore, a large diameter part is made in barrel assembly to be stored in the housing and a recess is mad in the axis hole of a housing, thereby preventing rotation of the assembly in insertion. Thus, it is possible to connect with the adaptor while optical loss is suppressed.

Abstract: PROBLEM TO BE SOLVED: To provide an adjusting wrench for adjusting an optical fiber connector. SOLUTION: The limited part extending from the enlarged part of an adjusting wrench is provided with the diameter larger than that of the opening of the ferrule housing part of an optical connector. A tubular member is projected from the limited part and the dimension of inside diameter is decided so as to slide the ferrule of the connector. The end of the tubular member 91 is provided with a pair of tanks 92, 93, which are composed so as to be adaptable to the inside of the front of the flange part of the ferrule barrel member of the connector or to the opening existing in the inside of the front. The distance from the surface of the limited member 86 to the tank is set so that the flange 26 is moved backward from meshing with the housing or the surface of the limited member 86 is abutted against the front surface of the housing before a spring member is bottomed within the housing by a pressure in the axial direction by means of the wrench. A ferrule barrel assembly is rotated with the wrench and whereby the angular direction of the eccentric vector of the ferrule is changed.
