Polishing bare fiber using the Micro-G® System
To polish fiber using the Micro-G® system follow these steps.
1. Load fibers into the bare fiber adaptors and insert them into the
polishing fixture on the APM-HDC-5400 series machine. Be careful
that the protrusion of the fiber from the ferrule end face is less
than 250 microns when loading.
2. After all fibers are loaded into the bare fiber adaptors and
adaptors have been inserted into the polishing fixture, inspect the
fiber protrusion using the DE2910 Videoscope.

3. While inspecting the fibers look for the fiber with the longest
protrusion and measure its length using the DE2910 Videoscope
software.
4. Measure the distance between the tip of the longest protruding
fiber and the glass plate surface using the DE2910 Videoscope.
5. Determine how much removal is desired on the fibers (for Step 1)
and enter the correct parameters into the MICRO-G® recipe
under step 1.
For example: fiber is 250 microns long and distance to the glass
plate is 2000 microns.
Parameters for 200 microns of removal could be as follows:
Initial move: 1950 microns
Feed Speed: 50 microns/sec
Step Move: 5 microns
Dwell Time: 10 seconds
# Of moves: 50
Final Dwell: 30 seconds
