Fiber proof testers are created to apply a set load to SZ stranding line to be able to test the effectiveness of the spliced fiber. Our fiber proof testers can be found in both linear and rotary designs, for 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 which are also competent at stripping, cleaning, cleaving, splicing, and 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 your stripped fiber, offering more flexibility than a heat-shrink protection sleeve, enabling that it is handled and coiled without damaging the fusion-spliced section. The integrated linear or rotary proof tester allows users to right away test a recoated fiber with a pre-determined load and find out the long-term longevity of the fiber. Because of the capacity 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 procedure starts with the fusion-spliced portion of fiber being placed in the center of the mold assembly (see image to the correct). 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 may then be tested by pulling into it as much as a pre-determined load.
Recoater and Mold Assembly Options – Recoaters can be found with either an automated or manual mold assembly. The automatic mold assembly features pneumatic control of the mold plates and it is optimized for high-volume manufacturing applications. Manual mold assemblies, on the contrary, use hinged mold plates that provide more flexibility and are perfect for low-volume manufacturing or R&D applications. An automatic or manual volumetric dispensing pump and injection method is utilized to inject the recoat material in to the mold cavity.
The PTR208 automatic recoater comes standard having a mold assembly for SZ stranding line; For our manual recoaters (Item #s PTR206, PTR206B, PTR307, and PTR307B), the mold assembly is sold separately so that customers can choose the best mold coating diameter for application. Custom mold coating sizes are available up to Ø900 µm. Pre-installation of the mold assembly in the factory can also be available. Contact Tech Support to learn more about custom molds or factory assembly.
We provide 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 appropriate for both varieties of recoat material; other recoaters are suitable for the top-index material only. Our manual recoaters with an automatic injection system (Item #s PTR206 and PTR307) may be customized to work with both the low- and high-index recoat material; please contact Tech Support to learn more.
Proof Tester Options – The PTR206, PTR206B, and PTR208 Fiber Recoaters have an integrated linear proof tester, that can take the fiber up to a predetermined load (20 N) then releases it. The linear proof tester uses uojthk same fiber holding blocks as the recoater and therefore the fiber fails to need to be moved prior to 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 list of proof test grips is included; replacement proof test grips can be purchased below in packs of 10. Each testing process is fully programmable through the included handset or tablet controller, allowing the user to choose parameters like the load, the pace at which the burden is used, as well as the hold time.
Inserts for Fiber Holding Blocks – Along with the above, we provide you with a variety of inserts for use in the fiber holding blocks from the recoaters to be able to support a variety of FTTH cable production line. For recoaters using a rotary proof tester, the inserts are compatible with fiber coating diameters in a range from 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.
