Thorlabs offers a family of products to assist customers who would like to connectorize their bare fiber, including fiber polishing film for use with ceramic or stainless steel ferrules, polishing films, polishing pucks, polishing plates, and connectorization kits. We also offer instructions on how to polish a connector, including how to glue and cleave the fiber. A color manual can be purchased below, or it can be downloaded here for free. The components sold here are also available in kits, sold at the bottom of the page.

Calibrating the D50-SMA

Included with the D50-SMA is the D50-A calibration pin. To use this calibration pin, you will need an arbor press and a flat surface as a reference. Using the arbor press, press the calibration pin into the center hole of the puck. This will press the threaded part of the polishing puck into the flat disc until the end of the calibration pin is level with the bottom surface of the puck. This will ensure that the fiber is polished to the correct height in the SMA ferrule.

Hello, We have bought a fiber polishing set to polish damaged (already conectorized, polraziation maintaining) fibers. However, we find that the fiber tip does not stick out from the polishing disc and thus cannot be polished. How can one use this polishing set to polish damaged fiber tips? Kind regards

Response from Buki at Thorlabs: Thank you for your feedback. There is a calibration pin included with the D50-SMA. Please use an Arbor Press to press the pin down to the bottom of the puck and make sure there is room for the pin to extend the bottom of the puck. Then flip the puck on a solid surface and press the pin down. You can then remove the pin. We will add this information to our website. Please contact TechSupport@thorlabs.com if you have additional questions.

A response from Thorlabs to vincent.gosling: After some discussion with the engineers in the fiber business unit we are sending you a new polishing disc just incase the one you have doesnt meet specifications. Some burnt connectors can be repaired by polishing with a diamond polish, however, if the damage is too severe, it may be necessary to replace the connector. Thorlabs provides reconnectorization services, simply contact our technical support department for a quotation. Thank you for contacting us and if the new disk doesn’t solve your problem, please let us know.

My company recently purchased a polishing kit to repair a "burnt" fc/apc. Unfortunately the fibre doesnt sit proud of the polishing disc and therefore doesnt polish. Could you tell me whether there is another technique to repair fibres or , (as I expect) to confirm if it is beyond repair (without replacing the connector). Any information would be greatly appreciated. Many thanks Vince Gosling

Fiber Polishing/Lapping Film for Use with Ceramic Ferrules

Thorlabs offers lapping (polishing) sheets to polish a connector after the fiber has been epoxied into the ceramic ferrule. Polishing or Lapping Film is composed of tiny particles glued to a substrate. By moving the connector over the polishing film, excess material is removed and the fiber end is polished. Different grades of polishing film are used in successive polishing cycles. Each polishing cycle uses a finer grit paper.

Our diamond sheets have tiny diamond particles glued to a substrate of polyester with resin. We highly recommend a five step polishing process: the first four steps using diamond sheets in four different grit sizes of 30, 6, 3, and 1 µm, and the fifth using our final polishing sheets. To use, drop distilled water on to the sheet and polish in a figure-eight motion using an appropriate polishing puck (sold below).

Our Final Polishing Sheets (LFCF), which eliminate the need for slurry, are designed to be used as the last step in the fiber polishing process. These sheets are made by coating polyester film with precision-grade silicon dioxide. These sheets produce an excellent surface finish with minimal scratches and offer no binder contamination on the optical fiber during polishing.

We recommend using these sheets over the less expensive aluminum oxide/silicon carbide sheets when polishing ceramic or zirconia ferrules because they do not cause undercutting when polishing the connector like silicon carbide can. Undercutting occurs when the fiber material is removed more quickly than the ferrule material creating a dip just above the fiber. When the connector is mated to another connector, instead of obtaining a glass-to-glass interface, the air gap created by the undercutting causes a glass-air-glass interface and excess loss, which is undesirable.

Despite the higher upfront cost per sheet, each area of the sheet can be used up to 20 times instead of once, compared to the aluminum oxide/silicon carbide sheets featured below. This greatly increases its value. These 6” x 6” sheets should be used with our glass polishing plates and rubber mats (see below).

Note: The diamond and final polishing films are sold in packages of 5.

Fiber Polishing/Lapping Film for Use with Stainless Steel Ferrules

Thorlabs offers Aluminum Oxide and Silicon Carbide lapping / polishing sheets to polish a connector after the fiber has been epoxied into the ferrule. Lapping sheets are like sandpaper for optical connectors. Tiny aluminum oxide or silicon carbide particles are glued to a substrate of polyester with resin. Since we highly recommend a four step polishing process when using aluminum oxide or silicon carbide sheets, we offer our sheets in four different grit sizes: 3, 1, and 0.3 µm grits using Aluminum Oxide and 5 µm grit using Silicon Carbide.

Typically, each area of each sheet can only be used once to polish a single connector. Also, care should be taken when polishing your connector as these sheets can cause undercutting especially with ceramic or zirconia ferrules. Undercutting occurs when the fiber material is removed quicker than the ferrule material creating a dip just above the fiber. When the connector is mated to another connector, instead of getting a good glass-to-glass interface, the air gap created by the undercutting causes a glass-air-glass interface and undesirable excess loss.

These 13” x 9” sheets should be used with our glass polishing plates and rubber mats (see below).

Note: Aluminum oxide and silicon carbide sheets are sold in packages of 10.

Connectorized Fiber Polishing Pucks

In order to hold the fiber connector securely and to maintain the proper angle, a Manual Fiber Polishing Puck is used. The puck makes it easier to hold the connector against the polishing film and ensures an even polish. We offer polishing discs for six different connector types. Please note that discs are specific to the type of connector; they are not interchangeable.

FC/PC and SC/PC Connector Polishing Disc
This polishing disc will accommodate both flat and pre-radiused connectors.

FC/APC Connector Polishing Disc
This polishing disc is designed to polish ferrules at 8° while securing the connector key in the proper orientation with respect to the polish angle.

SMA Connector Polishing Disc
This polishing disc will accommodate both SMA type 905 and SMA type 906 connectors. Each disc is factory set to produce the correct ferrule length after polishing is complete. The D50-SMA polishing disc can be recalibrated using our D50-A calibration pin, which is included with the D50-SMA polishing disc. For information on the recalibration procedure, please view the D50-SMA Calibration tab above.

ST/PC or LC/PC Connector Polishing Disc
These polishing discs are designed to allow the ST/PC (D50-ST) or LC/PC (D50-LC) connector to float. This design allows the polishing of both flat and pre-radiused connectors.

Bare Ferrule Polishing Pucks

D50-F with jig, ferrule, and hex key
Click to Enlarge
D50-F Polishing Puck in Jig with Secured Ferrule

Thorlabs’ bare ferrule polishing pucks provide a convenient and secure platform to evenly polish bare ferrules. Each puck includes a jig that is used to set the depth of the ferrule and a setscrew that firmly holds the ferrule in the puck. To use, simply place the puck on the jig, drop the ferrule into place, and tighten down the setscrew with the included 0.050" hex key (see image to the right). The puck will ensure that the ferrule is held perpendicular to the polishing surface while allowing the user to polish by holding the puck instead of the ferrule. During the polishing process, it may be necessary to return the puck to the jig in order to reset the proper depth. This simple yet practical device alleviates concerns of damaging or breaking the fiber while polishing the ferrule.

We offer the D50-F polishing puck for FC/PC and SC/PC ferrules and the D50-L for LC/PC ferrules.

Polishing Pad on Glass Polishing Plate

Glass Polishing Plate
Polishing of fiber optic connectors requires a flat, hard surface. The glass plate is produced from safety glass with all edges and corners rounded. Rubber feet help to ensure the plate will not mar the work surface and keep the plate from sliding. These 5 feet, located at the four corners and center of the plate, raise the top of the glass to a height of 0.5" (12.7 mm).

Polishing Pad
This solid silicone polishing pad (50 Durometer) is required when polishing PC-style pre-radiused connectors. When used with our glass polishing plate, as shown in the photo to the right, the pad helps to maintain the radius of the connector tip during polishing. This pad is 8.75" x 13" (22.2 mm x 33.0 mm) and 0.124" (3.15 mm) thick uncompressed.

We Recommend Using the FS200 Fiber Inspection Scope with the TUK05 Kit
  • Repair Fiber Optic Connectors with Scratched End Faces
  • Compatible with FC/PC and FC/APC Connectors with Ceramic Ferrules
  • Repair Approximately 20 Connector End Faces with the Included Lapping Film

A fiber optic connector end face is an optical-quality surface that needs to be free of dirt and scratches for optimal performance. When cleaning the end face is not effective, Thorlabs' TUK05 Touch-Up Polishing Kit allows worn fiber connector end faces to be repaired by polishing out the scratches.

The kit includes polishing supplies and complete repair instructions, all housed in a convenient carrying case. The kit has components compatible with FC/PC and FC/APC ceramic ferrule connectors and has enough polishing film to repair approximately 20 connector end faces.

Connectors can generally be repolished 10 times before reconnectorization is necessary. For replacement of worn or marred connectors, contact Thorlabs' tech support for assistance.

Kit Expansion Options
We strongly recommend using the FS200 fiber optic inspection scope with this kit. To repair different connector types, additional polishing pucks can be purchased separately. Our aluminum oxide polishing film can be used with this kit to polish steel ferrule connectors, and rougher grits of diamond lapping film can be used to repair deeply scratched connectors (see the User's Manual for details).

The carrying case has extra storage slots for the FS200 microscope, two extra polishing pucks, and one extra dropper bottle as well as space for additional lapping film. The case has removable foam inserts (see photo to the left) for reuse or storage of other components.
