Splice Station with PM Alignment (Item #s FFS2000PM and FFS200WS)
Figure 10 Rotary Splice Station
Splice Head: The splice head contains the tungsten or iridium filament, viewing optics, and XY
illuminators. It moves axially during the high-strength fire polishing process.
Filament Port: The filament port allows argon to escape during the splice process.
Mirror Toggle: The mirror toggle is used to switch between the side view (for XY alignment) and the end
view (for PM alignment).
Fiber Positioner: The stepper-motor pivot positioner is used for aligning fibers in the XY-direction with a
resolution of 0.01 μm.
Vacuum V-Groove Fiber Holders: The vacuum v-grooves are used to position the stripped fiber. The
non-abrasive material maintains the fiber strength.
Side Illuminators: The side illuminators are used to illuminate the cladding structure for end view during
rotary alignment.
Fiber Holding Block Drive Shaft: The drive shafts position the fiber holding blocks in Z-direction and
rotate the fiber for PM alignment.
Transfer Jig Bushings: The bushings are used to position transfer jig at the splice station.
3.5.8. Recoat Station
The recoat station is used to reinstate the polymer coating on the fiber, maintaining its strength and flexibility by
protecting the glass surface from damage. Liquid UV acrylate material is injected into the recoat cavity and cured
around the fiber using tungsten-halogen lamps to provide the necessary UV radiation.
