中断せざるを得なかった。DETAILED DESCRIPTION OF THE INVENTION The present invention aims at converting some or all of the light that has been transmitted in one direction at the connection point between two optical fibers into optical fibers that are different from the originally connected optical fibers. 7 This is related to an optical connector that can lead to an eyeglass. Since conventional optical connectors have a structure in which the tips of the optical fibers are connected by butting each other, it is possible to extract a part of the light that is propagated at the connector connection point. I couldn't. In addition, when guiding the light propagating through the Optical 7 Eyer to an Optical 7 Eyer other than the already connected Optical 7 Eyer, it was necessary to disconnect the connector section and connect it from '' to another connector. , during the switching, the light propagation had to be interrupted.
