Fiber proof testers are designed to apply a set load to SZ stranding line in order to test the strength of the spliced fiber. Our fiber proof testers are available in both linear and rotary designs, for both proof and tension testing. Fiber proof testers are available for single mode, multimode, and polarization-maintaining fibers. Select from dedicated, standalone systems or multipurpose designs that are also able to stripping, cleaning, cleaving, splicing, and/or recoating.
Fiber Recoaters with Proof Testers offer easy, integrated methods to recoat and test fusion-spliced fibers. The fiber recoating process restores the buffer coating to some stripped fiber, offering more flexibility compared to a heat-shrink protection sleeve, enabling it to be handled and coiled with no damage to the fusion-spliced section. The integrated linear or rotary proof tester allows users to instantly test a recoated fiber using a pre-determined load and find out the long term longevity of the fiber. Because of the capability to restore a fusion-spliced fiber to near original condition, these systems are perfect for applications like undersea optical fiber cables, submarine communication cabling, fiber lasers, or Distributed Bragg Reflector (DBR) lasers.
The process begins with the fusion-spliced section of fiber being placed in the center of the mold assembly (see image off to the right). Once placed in position, inserts within the fiber blocks secure the spliced fiber set up. Recoat material is pumped in to the cavity then UV-cured. The recoated fiber can then be tested by pulling onto it up to a pre-determined load.
Recoater and Mold Assembly Options – Recoaters are available with either a computerized or manual mold assembly. The automated mold assembly features pneumatic control of the mold plates and it is optimized for top-volume manufacturing applications. Manual mold assemblies, on the other hand, use hinged mold plates that provide more flexibility and are best for low-volume manufacturing or R&D applications. A computerized or manual volumetric dispensing pump and injection system is utilized to inject the recoat material in to the mold cavity.
The PTR208 automatic recoater comes standard having a mold assembly for optical fiber coloring machine; For the manual recoaters (Item #s PTR206, PTR206B, PTR307, and PTR307B), the mold assembly comes separately so that customers can select the right mold coating diameter for their application. Custom mold coating sizes can be found approximately Ø900 µm. Pre-setting up the mold assembly in the factory is also available. Contact Tech Support to learn more about custom molds or factory assembly.
We offer both high-index (Item # AB950200) and low-index (Item # PC373) recoat materials to use in these recoaters. Recoaters with manual injection pumps (Item #s PTR206B and PTR307B) are compatible with both kinds of recoat material; all the other recoaters are suitable for the high-index material only. Our manual recoaters with the automatic injection system (Item #s PTR206 and PTR307) may be customized to work with the low- and-index recoat material; please contact Tech Support for more information.
Proof Tester Options – The PTR206, PTR206B, and PTR208 Fiber Recoaters have an incorporated linear proof tester, which takes the fiber up to a predetermined load (20 N) and then releases it. The linear proof tester uses uojthk same fiber holding blocks since the recoater and therefore the fiber does not must be moved before testing. The PTR307 and PTR307B Fiber Recoaters include a built-in 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 can be purchased below in packs of 10. Each testing process is fully programmable via the included handset or tablet controller, allowing an individual to pick parameters including the load, the pace at which the burden is applied, and also the hold time.
Inserts for Fiber Holding Blocks – As well as the above, we offer a number of inserts to be used in the fiber holding blocks from the recoaters so that you can support a variety of Secondary coating line. 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 with a linear proof tester, the inserts cover a range for fiber coatings from Ø250 µm to Ø900 µm.
