  • Push Buttons on Recoaters Start and Stop Recoat Process
  • Durable Quartz Mold Plate Capable of >10 000 Recoats
  • Replacement Components Sold Separately Below

Thorlabs' Vytran® Fiber Recoaters restore the coating to a fusion-spliced fiber. The recoat material is injected through a cross-channel in the top plate into the mold assembly and then cured by ultraviolet (UV) LEDs. The LEDs provide faster cure times and longer lifetimes than the halogen lamps used in other fiber recoaters. One recoater with an automatic mold assembly is available; other recoaters use manual mold assemblies. Our automatic recoater utilizes a pneumatic mold assembly that directly injects recoat material into the mold cavity while our manual recoaters use a hinged top that can be opened and closed by hand. Both the automatic and manual recoaters use a split-quartz mold. The mold's surface is coated to prevent any recoat material that migrates between the plates from curing and forming imperfections on the finished recoat.

Each recoater uses a volumetric dispensing pump to inject the recoat material into the mold cavity; the PTR305 and PTR403 recoaters incorporate automatic injection systems while the PTR403B and PTR404B recoater have manual injection systems. The recoated fiber is then cured by UV LEDs integrated within the mold assembly housing. The fiber recoating process restores the buffer coating to a stripped fiber, giving it the same flexibility as when originally manufactured. Unlike standard heat shrink protection sleeves, a recoated fiber can be handled and coiled normally, without risking the fusion-spliced section of fiber.

The recoat process starts with the fusion-spliced section of fiber being placed in the middle of the mold assembly. Once set in position, inserts in the fiber holding blocks secure the spliced fiber in place. Recoat material is pumped into the cavity and then UV-cured. Due to their ability to restore a fusion-spliced fiber to original condition, fiber recoaters are ideal for manufacturing high-stress or sensitive fibers such as undersea optical fiber cables, submarine communication cabling, fiber lasers, or Distributed Bragg Reflector (DBR) lasers.

See the Tutorial Videos tab for information on the various options available for recoaters and a demonstration of how to perform a fiber recoat.

Mold Assemblies
The PTR305 automatic recoater comes standard with a mold assembly for Ø430 µm coated fibers. For our recoaters using manual mold assemblies, the mold assemblies are sold separately so that customers can choose the right mold for the coating diameter in their application. Custom mold coating sizes are available up to Ø900 µm. Pre-installation of the mold assembly at the factory is also available. Contact Tech Support for more information on custom molds or factory assembly.

Inserts for Fiber Holding Blocks
In addition to the above, we offer a variety of inserts for use in the fiber holding blocks of the recoaters in order to support a wide range of fiber coating diameters; a total of four inserts are necessary for each recoater (two top inserts and two bottom inserts). See the subgroup below for details.

Recoat Materials
Thorlabs offers both high-index (Item # AB950200) and low-index (Item # PC373) recoat materials for use in these recoaters. Recoaters with manual injection pumps (Item #s PTR403B and PTR404B) are compatible with both types of recoat material; the automatic injection pump of the PTR305 and PTR403 recoaters is compatible with the high-index material only. The automatic injector can be customized to work with both the low- and high-index recoat material; please contact Tech Support for more information.

Thorlabs' Automatic Fiber Recoater completely automates the fiber recoat process; fully programmable, it can be operated either through the handset controller (which gives full programming capabilities) or via buttons on the top of the machine. 

Our PTR305 Automatic Fiber Recoater uses a pneumatic mold assembly to control the mold plates. This design allows the recoat material to be directly injected into the mold cavity, eliminating any excess material, which would require cleaning after every recoat. Additionally, once the fiber is secured in the fiber holding blocks, the entire recoat process is performed automatically. This clean, automated process makes the PTR305 ideal for high-volume manufacturing. This recoater is designed for fiber coatings of Ø430 µm and requires the purchase of fiber block inserts (sold below). Choose the inserts that match the coating diameter of the fiber being used. It is compatible with high-index recoat material only (sold below). The pneumatic design of the mold assembly requires an external 80 - 120 psi compressed air source (not available from Thorlabs).

A handset controller, which comes standard with the PTR305, allows the user to control and program the unit. All recoat parameters can be set through this controller. 

Customized mold sizes for recoat diameters up to 900 µm are available; please contact Tech Support for more information.

The Mold Assemblies are composed of split quartz mold plates which, when closed, form the cylindrical mold cavity around the exposed section of the fiber being recoated. They are available for Ø280 µm, Ø430 µm, or Ø600 µm fiber coatings and in maximum fiber recoat lengths of 50 mm (compatible with Item #s PTR403 and PTR403B) or 100 mm (compatible with Item # PTR404B). Custom mold sizes up to Ø900 µm are available; please contact Tech Support for more information. Mold assemblies with a 50 mm recoat length feature a lever to assist with opening or closing the mold.

Recoat material (sold below) is injected into the mold assembly by either an automatic or manual injection system. Then, UV light from the integrated LEDs cures the recoat material. Cure times range from 15 s to 90 s depending on mold size and recoat material. The recoater mold assembly should be cleaned throughly with isopropyl alcohol or acetone between each recoating process; reliable and repeatable performance is highly dependent on the cleanliness of the mold.

When purchasing a manual fiber recoater for the first time, it is necessary to choose a mold assembly that is appropriate for the chosen recoater and desired fiber coating diameter. Additional mold assemblies may also be purchased and swapped out by the user. The assembly simply screws to the top of the device, making the removal and install simple and easy. Because of this, our manual recoaters are adaptable and flexible in the field and can be modified to accept varying diameters of fiber quickly. A recoater mold can be factory installed prior to shipment upon request by contacting Tech Support. It is also necessary to order the proper inserts (sold below) that best match the fiber diameter being used, whether purchasing a fiber recoater for the first time or updating a current recoater for a different fiber diameter.

Please note that these mold assemblies are only for the manual recoaters (Item #s PTR403, PTR403B, and PTR404B). Each PTR305 automatic recoater is sold with its own assembly already installed.

The manual injector is mounted to the recoater via two 4-40 mounting screws.

    • Accept PC373 and AB950200 Recoat Materials
  • Replacement Injection Tubes for Recoaters with Manual Injectors
  • Replacement Syringe Barrel for Manual Injectors

These manual injectors and injection tubes are available as replacement parts for Thorlabs' Vytran Fiber Recoaters with Manual Injectors; compatible systems are listed to the right. We also offer a replacement syringe barrel.

Each injector can be mounted to compatible fiber recoaters via two 4-40, 3/32" hex screws on the recoater housing (see photo to the right). To connect the injector to the recoater mold, tighten the connector at the end of the green plastic tubing, then loosen by a 1/4 turn to allow for rotation.

The injector is equipped with a distribution valve and two-position selection lever for directing the flow of recoat material. A knurled dispensing screw with an internal plunger acts as a syringe for the recoat material. To fill the syringe, point the lever downward (i.e., toward the recoat bottle), then rotate the knurled dispensing screw counterclockwise until it spins freely to fill the syringe (shown in the photo to the right). Then, to inject the recoat material into the mold, point the lever horizontally (i.e., facing the knurled screw) and rotate the screw clockwise until near the end of the travel range is reached. Avoid bottoming out the dispenser as this may damage the internal plunger; also take care when re-engaging the threads to avoid cross threading the dispensing screw. Several fill/inject steps may be needed until air is displaced within the system. Use lens tissue and an acetone or alcohol cleaning solution to collect any excess recoat material that flows from the mold.

Each injection tube and the RRMS syringe barrel are available as replacement parts for the manual injectors. The injection tube should be changed out if the knurl fitting breaks off the end, it leaks recoat material, or a clog forms that cannot be cleared with acetone. If the syringe no longer injects or an excessive number of air bubbles are visible in the recoat material (even after flushing the system), the syringe barrel should be replaced. A 5/16" thin spanner wrench is required for securing the syringe onto the recoat injector. Detailed installation instructions are provided in the support documentation, which can be found by clicking on the red documents icon () next to each item number.

  • LDC450B Portable Fiber Cleaver
  • PTR303(B), PTR304(B), PTR306(B), PTR307(B), PTR403(B), PTR404B, PTR406(B), and PTR407(B) Manual Mold Fiber Recoaters

  • PTR301 and PTR302 Fiber Proof Tester
  • Provides Full Functionality for Compatible Systems (See Compatible Systems List to the Right)
  • Intuitive GUI
  • Capacitive Touchscreen
  • Small Footprint

This handset controller is available as an alternative to the tablet controller previously included with our Vytran Large Diameter Fiber Cleavers, PTR Series Fiber Recoaters, and PTR Series Fiber Proof Testers. One handset controller is included with each new PTR series recoater system. A single handset controller can be used with multiple systems; after configuring parameters for one fiber processing unit, the controller can be disconnected and then connected to a different unit, of the same or a different type, to configure its parameters.

The handset controller must be connected via the included cable in order to use it. The controller automatically turns on when the connected system is turned on. Upon startup, the handset controller will always read parameters from the connected system; i.e., the parameters that appear on the screen will always be the parameters that have been uploaded to the connected unit. If the parameters read from the unit match the parameters of the most recently opened file on the handset controller, the screen will display the file name.

The suite of tools available through the handset controller includes a record of the total cure time of the machine (under Process Counters) that is not shown on the tablet controller. This value may be reset each time the bulbs are replaced.

The handset controller can open, save, delete, export, and import files containing parameters for compatible systems. Exporting or importing a file will require a memory device to be connected to the Program Port of the handset controller.

Instructions for using this controller can be found in the manuals for the compatible Vytran systems.
