Fiber proof testers are created to use a set load to optical fiber coloring machine in order to test the potency of the spliced fiber. Our fiber proof testers can be found 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. Choose 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 a stripped fiber, offering more flexibility compared to 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 instantly test a recoated fiber using a pre-determined load and determine the long-term reliability of the fiber. Because of the capability 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 procedure begins with the fusion-spliced portion of fiber being placed in the middle of the mold assembly (see image off to the right). Once set in position, inserts in the fiber blocks secure the spliced fiber set up. Recoat material is pumped into the cavity and 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 over the mold plates and is also optimized for top-volume manufacturing applications. Manual mold assemblies, on the other hand, use hinged mold plates that provide more flexibility and are perfect for low-volume manufacturing or R&D applications. A computerized or manual volumetric dispensing pump and injection product is utilized 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 comes separately in order that customers can choose the right mold coating diameter for their application. Custom mold coating sizes are available approximately Ø900 µm. Pre-installing of the mold assembly at the factory is also 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 for use during these recoaters. Recoaters with manual injection pumps (Item #s PTR206B and PTR307B) are compatible with both varieties of recoat material; all the other recoaters are suitable for the top-index material only. Our manual recoaters with the automatic injection system (Item #s PTR206 and PTR307) may be customized to work with both low- and high-index recoat material; please contact Tech Support for more information.
Proof Tester Options – The PTR206, PTR206B, and PTR208 Fiber Recoaters come with an incorporated linear proof tester, which takes the fiber up to and including predetermined load (20 N) then releases it. The linear proof tester uses uojthk same fiber holding blocks since the recoater and thus the fiber will not must be moved before testing. The PTR307 and PTR307B Fiber Recoaters have an incorporated rotary proof tester, which could 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 through the included handset or tablet controller, allowing an individual to pick parameters like the load, the pace at which the load is applied, and also the hold time.
Inserts for Fiber Holding Blocks – Along with the above, we offer a number of inserts to use inside the fiber holding blocks from the recoaters so that you can support a variety of optical fiber ribbon machine. For recoaters having a rotary proof tester, the inserts are appropriate for fiber coating diameters in a range between 125 µm to 900 µm. For recoaters having a linear proof tester, the inserts cover a range for fiber coatings from Ø250 µm to Ø900 µm.
