Fiber proof testers are created to apply a set load to optical fiber coloring machine to be able to test the strength of the spliced fiber. Our fiber proof testers can be purchased in both linear and rotary designs, for proof and tension testing. Fiber proof testers are available for single mode, multimode, and polarization-maintaining fibers. Choose from dedicated, standalone systems or multi-purpose designs which are also competent at stripping, cleaning, cleaving, splicing, and/or recoating.
Fiber Recoaters with 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 that it is handled and coiled with no damage to 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 longevity of the fiber. Due to their capacity to restore a fusion-spliced fiber to near original condition, these systems are best for applications including undersea optical fiber cables, submarine communication cabling, fiber lasers, or Distributed Bragg Reflector (DBR) lasers.
The process starts off with the fusion-spliced section of fiber being placed in the middle of the mold assembly (see image to the correct). Once set in position, inserts in the fiber blocks secure the spliced fiber in position. Recoat material is pumped into the cavity and then UV-cured. The recoated fiber can then be tested by pulling into it up to a pre-determined load.
Recoater and Mold Assembly Options – Recoaters can be purchased with either an automatic or manual mold assembly. The automatic mold assembly features pneumatic control of the mold plates and is also optimized for high-volume manufacturing applications. Manual mold assemblies, on the other hand, use hinged mold plates which provide more flexibility and are best for low-volume manufacturing or R&D applications. An automated or manual volumetric dispensing pump and injection system is used to inject the recoat material into the mold cavity.
The PTR208 automatic recoater comes standard using a mold assembly for SZ stranding line; For the manual recoaters (Item #s PTR206, PTR206B, PTR307, and PTR307B), the mold assembly is sold separately in order that customers can choose the right mold coating diameter for his or her application. Custom mold coating sizes can be purchased as much as Ø900 µm. Pre-installing of the mold assembly at the factory can also be available. Contact Tech Support to learn more about custom molds or factory assembly.
We provide you with both high-index (Item # AB950200) and low-index (Item # PC373) recoat materials to be used during these recoaters. Recoaters with manual injection pumps (Item #s PTR206B and PTR307B) are appropriate for both types of recoat material; other recoaters are appropriate for the top-index material only. Our manual recoaters with the automatic injection system (Item #s PTR206 and PTR307) may be customized to do business with both the low- and high-index recoat material; please contact Tech Support for additional information.
Proof Tester Options – The PTR206, PTR206B, and PTR208 Fiber Recoaters come with a built-in linear proof tester, which takes the fiber as much as a predetermined load (20 N) then releases it. The linear proof tester uses uojthk same fiber holding blocks as the recoater and so the fiber fails to must be moved prior to testing. The PTR307 and PTR307B Fiber Recoaters come with an incorporated rotary proof tester, which could perform both proof and tension tests (?89 N). One group of proof test grips is included; replacement proof test grips are available below in packs of 10. Each testing process is fully programmable using the included handset or tablet controller, allowing the user to pick parameters like the load, the speed where the burden is applied, as well as the hold time.
Inserts for Fiber Holding Blocks – In addition to the above, we provide a variety of inserts to use inside the fiber holding blocks from the recoaters so that you can support a variety of Fiber drawing machine. For recoaters with a rotary proof tester, the inserts are appropriate for fiber coating diameters in a range from 125 µm to 900 µm. For recoaters using a linear proof tester, the inserts cover a range for fiber coatings from Ø250 µm to Ø900 µm.
