Abstract
An optical connection detecting device has in a front face thereof a light emission display portion for detecting an optical connection, and in both front and rear ends of a lower face thereof a switch lever for detecting the optical connection. In an optical adapter, ferrule leading end portions of optical connector plugs inserted from fitting portions in both ends are butt jointed, leading ends of the switch levers in both front and rear ends of the optical connection detecting device are faced to notch concave portions which are formed in upper wall sides of opening ends of both the fitting portions of the optical adapter. When the optical connector plug is fully inserted into the fitting portion of the optical adapter instead of being in a half-inserted state, the switch lever is pushed up and the light emission display portion is displayed with an on-state lighting color.
