Abstract

PURPOSE:To make it possible to select a position where connection loss is minimum, by mounting the erroneous insertion preventing ring, which has a concave part to be fitted to the dowel for positioning provided in the flange of the plug, onto the groove provided on the end face of the adapter to give a constitution where the ring can be rotated together with the plug in one body. CONSTITUTION:After erroneous insertion preventing ring 14b is fitted to groove 19b provided on end face 18b of adapter 12 and is fixed by screw 20b, plug 11b having optical fiber 10b is inserted to insertion hole 17 of adapter 12, and dowel 16b for positioning provided in flange 15b is fitted to concave part 21b of ring 14b. Next, dowel 16a for positioning is fitted to the concave part of ring 14a similarly under the state where ring 14a is not fixed, and plug 11a is rotated while measuring connection loss of the connector to fix ring 14a in the minimum loss position by screw 20a. After ring 14b is fixed after screw 20b is relaxed to perform the similar test. cap nuts 13a and 13b are tightened to adapter 12. As a result, the position where connection loss is minimum can be determined.
