Abstract: A multi-fiber ferrule has lenses that have different prescriptions to disperse the light emitted from the multi-fiber ferrule. Alternatively, the lens for each individual optical fiber can be moved relative to the optical fiber or the optical fiber opening in the multi-fiber ferrule to cause the laser beam exiting the multi-fiber ferrule to be redirected into a structure that absorbs or blocks the laser.

Abstract: An optical module for preventing laser beam leakage and a control method thereof are disclosed. The optical module including a current control circuit, a first transistor, a laser, and a laser control unit. The laser control unit is configured to: if it is detected that an optical fiber is inserted in the optical fiber interface, perform control to turn on the laser, or if it is detected that no optical fiber is inserted in the optical fiber interface, control the laser to remain in an off state. A laser beam is effectively prevented from causing human bodily injury when an optical fiber is not inserted in an optical fiber interface.

Abstract: A lens of a plug converts a light signal from an optical fiber cable to light of a predetermined divergence angle in order to emit the light. A plug housing fixes the optical fiber cable and the lens. The lens is positioned such that the light signal from the optical fiber cable becomes the light of the predetermined divergence angle at an emission surface side of the optical fiber cable. The light signal emitted from the plug becomes dispersed when entering into the eyeball of a nearby person, and therefore can be prevented from exerting adverse effect on visual function and the like.

Abstract: An optical connector plug with a shutter to be fitted to an optical connector adapter includes: a plug frame configured to hold a ferrule; a square cylindrical front housing including a shutter that opens and closes with a movement of the ferrule; a locking housing fixedly and integrally connected to the plug frame and configured to be fitted into and be locked with the optical connector adapter; and a spring that biases the front housing forward. The plug frame is moved forward by a rearward movement of the front housing, a front opening edge portion of the plug frame expands a shutter into a straight shape, and the shutter includes slits straddling over a boundary between a flat portion and a curved portion when light is blocked, and a protrusion formed by a center portion being deformed by the expanded shutter when being fitted is cancelled.

Abstract: An optical fiber adapter according to the present disclosure includes a main body, an inner housing, an elastic shutter member and a spring. The main body has an axial accommodation room defined by a first wall, a second wall, a third wall and a fourth wall. The accommodation room has opposing first and second openings in the axial direction. The inner housing is placed within the accommodation room and includes a hollow cylinder extending from the front surface of a flange. The shutter member is positioned within the accommodation room and includes a base portion, a shutter plate and a connecting portion. The connecting portion connects the base portion with the shutter plate. The shutter plate extends from the connecting portion and arrives in front of an opening of the hollow cylinder. The shutter plate is movable with respect to the base portion. The spring is positioned within the accommodation room to push the shutter member toward the first opening of the accommodation room.
