<p>An optical functioning component has a tubular housing with a front end side having substantially the same shape as that of a front end of a removable plug housing of an optical connector plug. A rear end side of the tubular housing has a shape configured for connection to the optical connector plug when the plug housing is removed from the optical connector plug. A ferrule is provided on the front end side of the tubular housing and has a mechanism capable of attenuating, cutting-off, reflecting or absorbing a specific wavelength of light. An optical connection sleeve is connected to an end of the ferrule. A frame supports the ferrule and the optical connection sleeve and is mounted in the tubular housing for undergoing axial movement therein by a preselected amount.</p> |
