Thorlabs' Vytran® Fiber Recoaters and Proof Testers offer easy, integrated solutions to recoat and test fusion-spliced fibers. The fiber recoating process restores the buffer coating to a stripped fiber, offering more flexibility than a heat-shrink protection sleeve, enabling it to be handled and coiled without damaging the fusion-spliced section. The integrated linear or rotary proof tester allows users to immediately test a recoated fiber with a pre-determined load and determine the long-term reliability of the fiber. Due to their ability to restore a fusion-spliced fiber to near original condition, these systems are ideal for applications such as undersea optical fiber cables, submarine communication cabling, fiber lasers, or Distributed Bragg Reflector (DBR) lasers.

The process starts with the fusion-spliced section of fiber being placed in the middle of the mold assembly (see image to the right). Once set in position, inserts in the fiber blocks secure the spliced fiber in place. Recoat material is pumped into the cavity 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. The recoated fiber can then be tested by pulling on it up to a pre-determined load.

We also offer fiber recoaters with proof testers here that use halogen lamps for curing the fiber.

Recoater and Mold Assembly Options
Recoaters are available with either an automatic or manual mold assembly. The automatic mold assembly features pneumatic control of the mold plates and is optimized for high-volume manufacturing applications. Manual mold assemblies, on the other hand, use hinged mold plates that provide more flexibility and are ideal for low-volume manufacturing or R&D applications. An automatic or manual volumetric dispensing pump and injection system is used to inject the recoat material into the mold cavity.

The PTR308 automatic recoater comes standard with a mold assembly for Ø430 µm coated fibers. For our manual recoaters (Item #s PTR406, PTR406B, PTR407, and PTR407B), the mold assembly is sold separately so that customers can choose the right mold coating diameter for 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.

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 PTR406B and PTR407B) are compatible with both types of recoat material; all other recoaters are compatible with the high-index material only. Our manual recoaters with an automatic injection system (Item #s PTR406 and PTR407) can be customized to work with both the low- and high-index recoat material; please contact Tech Support for more information.

Proof Tester Options
The PTR308, PTR406, and PTR406B Fiber Recoaters come with an integrated linear proof tester, which takes the fiber up to a predetermined load (≤20 N) and then releases it. The linear proof tester uses the same fiber holding blocks as the recoater and thus the fiber does not need to be moved prior to testing. The PTR407 and PTR407B Fiber Recoaters come with an integrated rotary proof tester, which can perform both proof and tension tests (≤89 N). One set of proof test grips is included; replacement proof test grips are available below in packs of 10. Each testing process is fully programmable via the included handset controller, allowing the user to select parameters such as the load, the rate at which the load is applied, and the hold time.

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 fiber coating diameters from 80 µm to 1000 µm; 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. The manual injection pump of the PTR406B and PTR407B recoaters is compatible with both types of recoat material; the automatic injection pump of the PTR308, PTR406, and PTR407 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.

  • The mold should be cleaned with either acetone or isopropyl alcohol, applied with a cotton swab. If the mold has an accumulation of cured material stuck on the plates, allow the cleaning solution (preferably acetone) about 60 - 90 seconds to soften and lift the material from the surface.
  • The mold assembly of this recoater should be cleaned before the first recoating process of the day and then again after the last recoating process of the day.
  • Check the minimum short-term bend radius of the fiber to be tested to ensure its compatibility with the Ø2" mandrel.
  • The ramp rate is the rate at which the load is applied to the fiber.

Handset Controller GUI Interface

The VYT300C handset controller is included with the recoaters. It is also compatible with Vytran PTR series fiber recoaters and proof testers, as well as Vytran large-diameter fiber cleavers. One handset controller can be used to configure parameters on multiple fiber processing units in succession. Full instructions for using the handset controller can be found in the manual for each device. The screenshots below highlight key features of the graphical user interface.

The initial screen on the VYT300C Handset Controller gives the option to begin recoating and testing. Other menus can be accessed by swiping the touchscreen left or right, or by tapping the options at the top of the screen.

The Recoat and Test screen will display the status of the process that is running. The Stop button can be used to end the active Recoat or Test process. During a proof test and the injection process, the handset controller shows the parameters configured on the Edit tab.

During curing, the controller displays the parameters defined on the Edit tab and the progress of the cure. The Stop button can be used to end the active cure.

The suite of tools available through the handset controller includes some that are not shown on the tablet controller, such as a record of the total cure time of the machine. See the manuals of the compatible fiber recoaters for more information on these tools.

Thorlabs’ PTR308 Fiber Recoater features an automatic mold assembly and an integrated linear proof tester. The pneumatic mold assembly controls the mold plates allowing the recoat material to be directly injected into the mold cavity. This prevents the injection of excess recoat material, which would require cleaning after every recoat process. Additionally, once the fiber is secured in the fiber holding blocks, the entire recoat process is performed automatically.

The PTR308 recoater includes a handset controller that allows the user to program and control the unit. Adjustable settings include the inject rate, inject amount, cure time, LED power, and proof test level; this enables the programming of custom recipes. An injection calculator provides an estimate of recoat parameters that can be refined by the user. The controller is shipped preloaded with files for common recoat and proof test parameters, but can store a virtually unlimited number of files; please see the Controller tab for details.

The integrated linear proof tester takes the fiber up to a predetermined load (≤20 N) and then releases it. The testing process is programmable, allowing the user to select parameters such as the load, the rate at which the load is applied, and the hold time. To ensure the long-term reliability of the fiber, the proof test level should be about three times higher than the applied service load for the spliced fiber.

The PTR308 unit 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. Nylon-tipped setscrews are used to secure the inserts in the fiber holding blocks; replacement 2-56, 1/8" long SS2SN013 setscrews are available in packs of 10. The PTR308 unit 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). Customized mold sizes for recoat diameters up to 900 µm are available; please contact Tech Support for more information.

The PTR406 and PTR406B units combine a fiber recoater and linear proof tester into a single system. These recoaters use a hinged mold assembly (sold separately below) to form the mold cavity for recoating; recoat material is injected through a cross-channel in the mold’s top plate. The integrated linear proof tester can pull the recoated fiber up to a predetermined load (≤20 N) and uses the same fiber holding blocks as the recoater; therefore, both recoating and testing processes can be performed without moving the fiber.

Each recoater includes a controller that allows the user to program and control the unit. Adjustable settings include the inject rate, inject amount, cure time, LED power, and proof test level; this enables the programming of custom recipes. An injection calculator provides an estimate of recoat parameters that can be refined by the user. The controller is shipped preloaded with files for common recoat and proof test parameters, but can store a virtually unlimited number of files; please see the Controller tab for details.

Recoat Injector Configurations
Two recoat injector configurations are available. The PTR406 recoater uses an automated pump to inject the recoat material. The amount of material dispensed by the automatic injector can be controlled by hand via the top-mounted "Inject" button or programmed into the machine using the controller. The PTR406B features a manual recoat injection system that requires the user to manually dispense the recoat material into the mold cavity; a replacement injector for the PTR406B recoater is available below. Please note that the automatic injector is only compatible with high-index recoat material, while the manual injector is compatible with both low- and high- index recoat material; both are sold separately below. Please contact Tech Support for more information.

Selecting a Mold Assembly or Fiber Holder Inserts
When selecting one of these recoaters, both a mold assembly (sold below) and inserts for the fiber holding blocks (two top and two bottom, sold below) must be chosen. The UV curing LEDs are housed within the mold assemblies for these recoaters; there is no UV curing source within the units themselves. The mold assemblies are available for coating diameters of 280 µm, 430 µm, and 600 µm. Customized recoat diameters up to 900 µm are also available; please contact Tech Support for more information. The type of insert is dependent upon the type of integrated proof tester. The recoaters with linear proof testers are compatible with the VHJ series inserts. Nylon-tipped setscrews are used to secure the inserts in the fiber holding blocks; replacement 2-56, 1/8" long SS2SN013 setscrews are available in packs of 10.

The PTR407 and PTR407B units combine a fiber recoater and rotary proof tester into a single system. These recoaters use a hinged mold assembly (sold separately below) to form the mold cavity for recoating; recoat material is injected through a cross-channel in the mold’s top plate. The integrated rotary proof tester can perform both proof and tension tests (≤89 N). Tension testing takes the fiber up to its breaking point, and the peak tension is recorded in units of tension (pounds, kilograms, or Newtons) or in units of stress (kpsi or GPa).

Each recoater includes a handset controller that allows the user to program and control the unit. Adjustable settings include the inject rate, inject amount, cure time, LED power, and proof test level; this enables the programming of custom recipes. An injection calculator provides an estimate of recoat parameters that can be refined by the user. The controller is shipped preloaded with files for common recoat and proof test parameters, but can store a virtually unlimited number of files; please see the Controller tab for details.

Recoat Injector Configurations

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. 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 thoroughly 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 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 PTR406(B) and PTR407(B)]. Each PTR308 automatic recoater is sold with its own assembly already installed.

  • PTR308/PTR406/PTR406B-Compatible Inserts Accept Fiber Coating Diameters from 80 µm to 1000 µm
  • PTR407/PTR407B-Compatible Inserts Accept Fiber Coating Diameters from 80 µm to 1000 µm
  • Choose Two Top Inserts and Two Bottom Inserts
  • Replacement Strips for Select VHJ Series Inserts Available Below

For all the recoaters sold above, the proper set of inserts need to be selected. A total of four inserts (two top and two bottom) are required for one unit. The inserts are seated in slots in the fiber holding blocks and secured with setscrews (included with the recoater). They can easily be swapped out, allowing the recoaters to adapt quickly to clamp fibers with different coating diameters. Note that the mold assembly (available above) also needs to be changed if a different recoat diameter is desired. These inserts are compatible with fiber coatings ranging from Ø80 µm to Ø1000 µm.

We offer three types of inserts. The VHJT series top inserts incorporate a rubber strip that ensures sufficient friction to hold fiber under tension, while the VHJ and VHV series bottom inserts feature V-groove designs for accurate, repeatable positioning for recoating. The VHJ series inserts have vacuum holes in the guides at each end while the VHV inserts incorporate vacuum holes directly in the V-grooves.

Custom sizes are available; please contact Tech Support for more information.

  • Replacement Manual Injector for Dispensing Recoat Material into the Mold
    • Accept PC373 and AB950200 Recoat Materials
  • Replacement Injection Tube for Recoaters with Manual Injectors
  • Replacement Syringe Barrel for Manual Injectors

The PTRRRM Manual Injector and RRMTA Injection Tube are available as replacement parts for Thorlabs' Vytran 50 mm Recoat Length Fiber Recoaters with Manual Injectors; compatible systems are listed to the right. We also offer a replacement syringe barrel (Item # RRMS).

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.

The RRMTA injection tube and the RRMS syringe barrel are available as replacement parts for the PTRRRM manual injector. 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.
