ている。i! In the case of one light-emitting and light-receiving element, especially a light-emitting element, as in the tT configuration, there is a large variation in optical output, and in order to obtain sufficient optical output through an optical connector, the distance between the element and the fiber must be 1v4y. However, most of the 6141 work involves inserting a light emitting element using a micro-insertion device, etc. while observing the light output with a meter, and once a certain level of light output is obtained, applying an adhesive and maintaining that state until it hardens. A surprising method has been adopted.

However, since the holding position does not change even if the holding position is changed, Ichihime-sakuhigashi and Katsoku-sakuhigashi can be divided, improving work efficiency. In addition, it is a version of JI7Jtlc that automates AI4 adjustment work.
