Abstract
A connector adapter including a light emitting element for emitting a laser beam and connected with a plug having an optical fiber, whereby the laser beam emitted from the light emitting element is introdued into the optical fiber. The connector adapter comprises a shutter member fixed in a connector and including a base portion having a first spring portion and a shutter portion connected to the base portion. The base portion undergoes elastic deformation at the first spring portion so that the shutter portion recedes from the optical path of the laser beam when the plug is pushed into the adapter to be attached thereto, and is restored from the elastic deformation so that the shutter portion intercepts the optical path of the laser beam when the plug is drawn out of the adapter to be detached therefrom.
