Safety OptiSpin™ is safe to operate by most trained personnel in most environments due to its lack of electrical components and it's manual operation. Always wear safety glasses when handling and polishing fiber optics to avoid possible eye injury. Dispose of any cleaved or broken glass fibers in accordance with accepted safety standards. -
Page 4: Introduction
OptiSpin™ also provides a means for flat-polish. Plastic fibers and stainless steel ferrules are a snap for OptiSpin™ . Thank you for taking time to learn more about OptiSpin™. Please read further about set-up, and then, polishing procedures. -
Page 5: Set-Up
Set-up OptiSpin™ comes to you ready to polish . The following procedures should be implemented only if your application requires some special modification or if the device should require adjustment in the future. Changing Bits The diagram below shows the "Block " and "Bit" assembly. The bit is affixed to the block by two screws with thumb wheels at point "A"... -
Page 6: Squaring Bit
Points "C","D", & "E" in figure 1 are adjustment ports for the bit. This 3- point adjustment feature allows the bit to be "squared" to the polishing film surface. Your OptiSpin™ bit was squared at the factory and no adjustment should be required. Adjustments to the bit may be made with an .050 allen wrench that is inserted through the adjustment ports until the... -

block and depress the button. Keeping the button depressed, slide the block to its new position and then release the button. Turn the hand wheel three or four rotations to make sure the screw drive threads are reseated. Spacing the Bit From the Polishing Disc Maintaining proper spacing between the bit and polishing film disc is necessary for efficient operation. -
Page 8: Model Descriptions
Models 140, 1100S • The Model 140 has a fixed gear ratio. This unit indexes the fiber across the polishing film at a rate of 140µm per 360º rotation of the polishing disc. -
Page 9: Polishing Disc
Polishing Discs Polishing discs are manufactured in four basic styles and all serve different purposes in the polishing process. Always select the properly designed polishing disc for your application. Polishing discs may be used with many commonly available polishing films. The discs are attached to the polishing wheel via small magnetic discs adhered to the back of the polishing disc. - Page 10 The Radius disc has a 1/16" 70 durometer neoprene pad adhered to its entire surface. This disc is used for epoxy removal as well as final polishing stages of connectors with pre- radiused ferrules. Either plain or PSA backed polishing films may be used. Plain backed films may be attached with just a few drops of water.
- Page 11 The process begins by making sure your machine is first set set to 140µm increments and that the bit is set at the center of the polishing disc. You want to make sure that the ferrule starts at the center of the Denub disc so that you can work your way out.
- Page 12 Once the fiber nub has dented the polishing film, hold the connector in one position and begin turning the hand wheel clockwise , slowly, for a turn or two and then pick up speed. The amount of turns required to complete denubbing will vary greatly depending on cleave length, polish grit, and pressure.

Page 13: General Operation
OptiSpin™ gives the operator greater control over the polishing process and more tools to aid in production of a quality product. No longer are you working upside down and blind. OptiSpin™ allows you to see, hear, and feel the polishing process as it occurs. - Page 14 Depending on the model purchased, the ferrule and fiber are indexed across the polishing film at either 140µm or 1100µm rates for each 360° rotation of the polishing wheel. Usually the connector is placed into the proper bit for the application and hand pressure is applied to the connector housing supplying the necessary pressure to accomplish the polishing task.

Page 15: Suggested Polishing Procedures
Suggested Polishing Procedures The OptiSpin™ system uses fewer steps than conventional polishing methods. Fewer steps are required due to the efficiency of the OptiSpin™ concept. OptiSpin™ also produces near-perfect connectors with respect to ferrule geometry. This is of particular importance when back- reflectance levels are at issue. - Page 16 2. Position the bit so that the ferrule is at the center of the disc. 3. Make sure that the indexing rate is set to 140µm. 4. Insert the connector into the bit and exert pressure so that the plastic fiber contacts the polish film solidly.
- Page 17 1. Apply 5µm silicon carbide polish film to the Denub Disc, load disc on machine. 2. Move bit so that ferrule starts in center of disc, then set to 140µm index rate.. 3. Insert connector into bit so that cleaved fiber nub dents polishing film slightly.
- Page 18 Singlemode Fibers Now a little more about denubbing. You will note in the previously described discussion and procedures for multimode fibers that care is taken not to allow the coarser grit films to remove the fiber nub flush with the ferrule surface. This serves two purposes: First, the best way to remove deep scratches from the ferrule surface is not to put them in the first place.
- Page 19 Denubbing with coarse grit films can damage the cladding edges. Pieces and chips of glass are torn from the cladding edge by the more abrasive polishing films. These chips can extend down the cladding wall for several microns as indicated by Figure 5. When the fiber is flush with the ferrule surface and observed with 400X inspection scopes, these chips can appear as if they are epoxy residue or some other contaminate stuck around the perimeter of the glue line (Figure 6).
- Page 20 Sometimes it seems more luck than skill in achieving a scratch free polish. OptiSpin™ offers two suggestions to make the process less painful. Use the optical swab in this final stage. You can dip it in alcohol or other fluid if you wish.
- Page 21 6. When the ferrule has entered zone 2, apply more pressure to the connector 7. Before the ferrule reaches zone 3, check to make certain that the fiber nub has been reduced to flush with the epoxy bead. Check with your fingertip.
