Equipment

Splicing Unit

The splicing unit was obtained in December of 2009 from Ron Richards of Michigan State University. Originally it had been used to fuse small round fibers. Some of the equipment has been modified to accommodate the square fibers that will be fused in the unit.

Ferrules

The ferrules are made of quartz, and are V shaped so that they make a hollow square cross-section when mated. This is so the fiber fits between them snugly while it is being fused.

A 2x2 mm square waveguide, 2 ferrules, and heat-shrink used to mount the ferrules and supports to the collars. The black residue on one of the ferrules is RTV and it is used in mounting ferrules to the collars.

Splicing Collars

Prototype collars designed for small round fibers. The top and bottom collars seem to be identical.
The supports and rounded ferrule are mounted.

Top collar, with ferrule and support mounted (machined specifically to mount 2x2mm square fibers).
Bottom collar, with ferrule and support mounted (machined specifically to mount 2x2mm square fibers).

Lamp

The lamp used in the fiber splicing unit is a 25 volt - 250 watt AV/Photo lamp.
