The receiver portion (712/912) is sized to accommodate the flange portion (710/910) of the stud (702/902) and the retention portion (714/914) is sized to accommodate the stem portion (708/908) but not the flange portion (710/910) of the stud (702/902). A third locking feature (705/905) prevents relative sliding between the two pieces of telecommunications equipment (610/810) once the stud stem portion (708/908) has been slid within the slot retention portion (714/914) and the stud flange portion (710/910) is out of alignment with the slot receiver portion (712/912).

A laser device includes: a laser unit that outputs laser light; an output end that launches the laser light; a first fusion splice portion; and a second fusion splice portion. In each of the first fusion splice portion and the second fusion splice portion, two multi-mode fibers are fusion-spliced. Each of the two multi-mode fibers include a core through which the laser light propagates and a cladding that surrounds the core. The first fusion splice portion is disposed closer to the laser unit than is the second fusion splice portion. At least a part of the core in the first fusion splice portion contains a dopant that is the same type as a dopant contained in the cladding in the first fusion splice portion for decreasing a refractive index.

A splicing structure, a splicing table, and a splicing and fitting device are provided. The splicing structure includes: a splicing adjustment component, a splicing alignment component, and a splicing base. The splicing adjustment component and the splicing alignment component are connected to the splicing base; and the splicing adjustment component is configured to support at least two to-be-spliced pieces; the splicing alignment component is configured to align the at least two to-be-spliced pieces to a first reference site. The splicing adjustment component is further configured to drive at least one of two adjacent to-be-spliced pieces in the at least two to-be-spliced pieces to move relative to the first reference site, to enable the two adjacent to-be-spliced pieces to be close to or far away from each other.

A fusion splicer for fusion-splicing a first group of optical fibers and a second group of optical fibers by arc discharge is disclosed. The fusion splicer includes first and second electrode rods, first and second fiber holding parts, and a first shield. The electrode rods generate the arc discharge therebetween. The first fiber holding part has a first plurality of V-grooves positioning the first group of optical fibers. The second fiber holding part has a second plurality of V-grooves positioning the second group of optical fibers. The first shield is located between the first and second plurality of V-grooves and the first electrode rod in a direction along a center line connecting a tip of the first electrode rod to a tip of the second electrode rod. The first shield is formed of an insulating material having heat resisting properties withstanding 1000 or more degrees Celsius.

A parallel position manipulator includes a top plate, a baseplate and a plurality of prismatic joint actuators. Each actuator includes an actuator joint having five Degrees of Freedom (DOF) at either the base plate or the top plate. When one or more of the actuators extends or contracts, the pivot points, or five DOF actuator joint, of the remaining actuators are allowed to shift in any axis other than that actuator's primary axis of motion.
