Then, the fixing plate (32) and the supporting plate (33) are arranged on the fixed plate (32) and then the fixing plate (32) is fixed by screws or the like to connect the pair of optical fibers (20).
ところが、この接続具(30)を製造する場合、各V溝
(31a)及び溝(32a)は相当の精度が要求される。However, when manufacturing the connector (30), each V groove (31a) and groove (32a) are required to have a considerable accuracy.

ればならないため、相当困難が伴なっているのである。The accuracy of each V groove (31a) and groove (32a) depends on the optical fiber (2
If it corresponds to 0), as shown in FIGS. 13 and 14, each optical fiber (20) is held at a predetermined position and the connection loss is small. If the accuracy is not good, as shown in Fig. 15, the optical fiber (20)
The position of the core wire (21) deviates from the normal position of the virtual line, resulting in a connection loss. To avoid this, each V
The groove (31a) and the groove (32a) must be finished with considerable accuracy, which makes the manufacturing of the connector (30) itself troublesome and increases its value. Further, not only is there a problem in the manufacturing of the connector (30) itself, but attention must also be paid to the accuracy required in the connection work, which is considerably difficult.
