Fiber proof testers are created to use a set load to optical fiber ribbon machine in order to test the potency 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. Pick from dedicated, standalone systems or multipurpose designs that are also competent at stripping, cleaning, cleaving, splicing, and recoating.
Fiber Recoaters with Proof Testers offer easy, integrated answers 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 it to be 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 figure out the long-term longevity of the fiber. Because of their capacity to restore a fusion-spliced fiber to near original condition, these systems are perfect 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 off to the right). Once placed in position, inserts inside the fiber blocks secure the spliced fiber set up. Recoat material is pumped to the cavity and after that 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 are available with either an automatic or manual mold assembly. The automatic 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 which provide more flexibility and are best 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 having a mold assembly for SZ stranding line; For our 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 application. Custom mold coating sizes are available as much as Ø900 µm. Pre-setting up the mold assembly at the factory is additionally available. Contact Tech Support for additional info on custom molds or factory assembly.
We offer both high-index (Item # AB950200) and low-index (Item # PC373) recoat materials to be used in these recoaters. Recoaters with manual injection pumps (Item #s PTR206B and PTR307B) are suitable for both kinds of recoat material; all the other recoaters are suitable for our prime-index material only. Our manual recoaters with the automatic injection system (Item #s PTR206 and PTR307) may be customized to work alongside both low- and-index recoat material; please contact Tech Support for more information.
Proof Tester Options – The PTR206, PTR206B, and PTR208 Fiber Recoaters come with a built-in linear proof tester, that can take the fiber up to and including predetermined load (20 N) and after that releases it. The linear proof tester uses uojthk same fiber holding blocks because the recoater and so the fiber will not have to be moved prior to testing. The PTR307 and PTR307B Fiber Recoaters come with a built-in 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 can be found below in packs of 10. Each testing process is fully programmable through the included handset or tablet controller, allowing the consumer to pick parameters such as the load, the rate at which the burden is used, and also the hold time.
Inserts for Fiber Holding Blocks – In addition to the above, we provide a number of inserts to be used inside the fiber holding blocks from the recoaters so that you can support a wide range of SZ stranding 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 having a linear proof tester, the inserts cover a range for fiber coatings from Ø250 µm to Ø900 µm.
