Introduction This manual covers polishing conditions and procedures with SFP-550 Polishing

Machine. The polishing conditions in this manual are standard and

recommendable for the polishing applicable to our optical zirconia ferrule.

Polishing conditions need to be changed applying to each connector type, ferrule

shape and material.

Note

Before Polishing, read Operating Manual and Maintenance Manual of SFP-550E

along with this manual.

8. Polishing Process Polishing process is depending on each ferrule shape, material, and connector type. Polish ferrules by an appropriate polishing condition described in the former sections. The following Polishing Process is regarding to general ferrule polishing using SFP-550S

8.1 Ferrule Mounting Check When ferrules are mounted to the polishing holder, please make sure that the tip of

ferrules protrude uniformly from the bottom of the holder.

A variety of the protrusion influence the quality of

polishing. Confirm the protrusion of the ferrules

after mounting, remove the ferrule if its protrusion

length is larger or shorter than others. Especially

the ferrule of short protrusion may not be mounted

completely because of adhesive on the side of the

ferrule. Clean the ferrule well and mount it to the

holder again. Do not remove the ferrules during

polishing processes.


37/40

8.2 Adhesive Removal Process (Right-angled convex polishing only) On the tip of the optical connector before polishing, adhesive and the optical fiber are

protrude. Remove the protruding adhesive according to the following steps to prevent

adhesive exfoliation and damage of the polishing films.

• Cut out the protruding fiber. Attach the polishing film to the polishing pad with

double-sided tape and remove the protruding adhesive. Go on to the next process

even if the adhesive remains after that removal except pre-domed ferrules and

angle-convex polishing ferrules. These pre-domed ferrules and angle-convex polishing

ferrules need to be polished until protruding adhesive is removed completely.

• In the case that the protruding adhesive is remaining on most of the ferrules after the

hand remove on the above, the hand polishing time might not be appropriate to the

shape of ferrule, material, or the quantity of adhesive. Those ferrules need to be

re-polished. It will happen that the damage of polishing film or wrong polishing shape

on the next process if the polishing process is continued without re-polishing.


38/40

8.3 Convex Shaping Process Check Check the convex shape of the ferrules with the reflection light of a fluorescent lamp

after the rough polishing step. The tip of the ferrule needs to have complete convex

shape at the point. If the shape is not complete, the polishing time might not be long

enough. Do the rough polishing again on the ferrule.

8.4 Cleaning of Polishing Holder

Polishing particles stuck to the polishing holder at the former polishing step may

be a cause for the damage of a polishing film and scratches of the ferrule tip at

the latter polishing step. After every polishing step, wipe the bottom side of the

polishing holder, especially the area around the ferrule tips shown the shaded

part in the bottom figure, by alcohol and lint-free tissue.


39/40

8.5 Cleaning of Polishing Film And Polishing Pad

Wipe and clean the polishing films used several times by alcohol and lint-free

tissue after every using. Oil and distilled water between the polishing pad and

the polishing film may accelerate the polishing film peeling and be cause for the

bad polishing result or damage of the polishing film. When the polishing film

cleaning, clean the area between the polishing pad and polishing film also and

keep the area free from the extraneous materials.

The following figure shows the area focusing on for cleaning.

8.6 Re-polishing

The ferrule needs to be re-polished if it has an scratch or crack of the fiber after

polishing. For any polishing condition, the re-polishing follows the same steps

starting from the step after adhesive removal. If the polishing result is still not

in good condition, change the polishing film because of its exhaustion.

Re-polish the ferrule because of the crack of the fiber. In this case,

the fiber was caught and adhesive was removed at the former

polishing process. Make sure not to give the pressure suddenly at

the adhesive removal step.

There are many superficial scratches on the fiber. In this case, the

protrusion length of the fiber was not enough. Or change the

polishing film because it is almost out of its service life.

There are slightly superficial scratches on the fiber. In this case,

the cleaning of the ferrule end faces was not complete and polishing

particles and dust of the former polishing process influenced the

following polishing. Re-polish the ferrule starting from the final

polishing. Clean the end faces of ferrules completely after every

polishing process.

• If there is no improvement with the counter plans on the above, inspect the polishing machine according to the maintenance manual.
