Abstract:
A pre-assembled optical fiber connector is provided that comprises a boot, a sleeve, a spacing sleeve, a tubular housing, a spring, an alignment ferrule, a push-pull insulative housing and a push-pull element which are assembled in series. The alignment ferrule has at least one engaging portion to engage the tubular housing so that the tubular housing, the spring and the alignment ferrule are pre-assembled.
Abstract:
A boot for an optical fiber connector according to the present invention is provided. The boot includes a hollow cylindrical body defining an axial direction, a protrusion portion formed on the cylindrical body, and a member with the property of plasticity disposed in the protrusion portion, wherein the member has at least one protrusion formed thereon The at least one protrusion sticks in the protrusion portion formed on the cylindrical body.
Abstract:
A one-piece LC type optical fiber adapter is provided. The LC type adapter of the present invention has fewer parts than a conventional one. Therefore, it is simpler and easier to assemble the LC type adapter of the present invention. In addition, the main body of the LC type adapter is unitary thereby avoiding the prior art problem that the stresses cause the two halves of the adapter to separate from each other after time.
Abstract:
An optical fiber connector includes a connector housing, a ferrule and a clamping assembly. The connector hosing has a front end and a rear end. The ferrule is disposed in the connector housing and projects from the front end of the connector housing. The clamping assembly is disposed in the connector housing for mounting the ferrule, and includes a hollow housing and a cam member, wherein the cam member includes a groove adapted to clamp a terminating fiber when a cam effect between the hollow housing and the cam member is generated and further the cam effect causes the groove of the cam member to generate a clamping force.

Abstract:
A fiber adapter includes a housing having a plurality of side walls, the side walls defining a receiving recess for mating with a fiber connector, and an attachable, integrally formed shutter member. The shutter member includes a clip portion having opposing first and second ends, the first end provided with a clip recess configured to attach to one of the side walls and the second end comprising a hook, wherein the clip portion is configured to secure the shutter member to the housing, a protrusion formed at the first end of the clip portion and configured to extend away from the housing, and a curved elastic shutter plate extending from the first end of the clip portion and into the receiving recess.

Abstract:
An adjustable attenuation adapter mainly comprises a fixing body having a bore centrally disposed therethrough and a connecting member extending outwardly from the bore; a moving body having a cylindrical body with a threaded outer surface; an inner roller being disposed within the central bore of the fixing body, the inner roller having an outer surface with gear teeth and an inner threaded surface for driving the threaded outer surface of the cylindrical body of the moving body; and an adjusting knob disposed within the fixing body and adjacent to the inner roller, the adjusting knob having a gear body for driving gear teeth of the inner roller. Since the threaded outer surface of the cylindrical body is threadedly driven by the inner threaded surface of the inner roller which is also gearedly rotated by the adjusting knob, the rotation of the adjusting knob causes the axial displacement of the moving body with respect to the fixing body.
Abstract:
A bimetal-based temperature stabilized multi-FBG package with tunable mechanism mainly includes a moving pin, a bimetal fixture, a rotation sleeve, a locking pin. The moving pin has a first predetermined outer screw pitch at one end and an elongated slot at the other end for receiving the locking pin. The bimetal fixture has a main frame and a plate secured to the main frame. The main frame of the bimetal fixture has a tube member extending outwardly from the side wall thereof, and the tube member has a second predetermined outer screw pitch at the distal end thereof. The rotation sleeve has a first predetermined inner thread corresponding to the first predetermined outer screw pitch of the moving pin and a second predetermined inner thread corresponding to the second predetermined outer screw pitch of the bimetal fixture. The grating fiber is first placed inside the moving pin and then the fiber is metallized or soldered to the moving pin and the holding arm of the bimetal fixture. The slot of the moving pin is guided by the locking pin which enables the linear movement of the moving pin. When the locking pin is in position, the moving pin cannot self-rotate, so rotating the sleeve in one cycle will make the moving pin has a movement of the second predetermined outer screw pitch minus the first predetermined outer screw pitch. Once the locking pin is rotated outwardly not to guide the slot, rotating the rotation sleeve 30 in 360 degrees will result in the second predetermined outer screw pitch (0.4 mm) movement of the moving pin, which called “quick movement”.
