Fiber proof testers are created to use a set load to optical fiber ribbon machine to be able to test the potency of the spliced fiber. Our fiber proof testers are available in both linear and rotary designs, both for proof and tension testing. Fiber proof testers are available for single mode, multimode, and polarization-maintaining fibers. Pick from dedicated, standalone systems or multi-purpose designs which are also capable of stripping, cleaning, cleaving, splicing, and/or 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 some stripped fiber, offering more flexibility than 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 having a pre-determined load and figure out the long term reliability of the fiber. Due to 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 procedure starts off with the fusion-spliced portion of fiber being placed in the center of the mold assembly (see image to the right). Once occur position, inserts in the fiber blocks secure the spliced fiber in place. Recoat material is pumped in to the cavity then UV-cured. The recoated fiber may then be tested by pulling on it up to and including 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 offer more flexibility and are best for low-volume manufacturing or R&D applications. A computerized or manual volumetric dispensing pump and injection product is used to inject the recoat material into the mold cavity.
The PTR208 automatic recoater comes standard with a mold assembly for SZ stranding line; For the manual recoaters (Item #s PTR206, PTR206B, PTR307, and PTR307B), the mold assembly is sold separately to ensure that customers can select the right mold coating diameter for application. Custom mold coating sizes are available as much as Ø900 µm. Pre-installation of the mold assembly in the factory is also available. Contact Tech Support for more information on custom molds or factory assembly.
We provide you with 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 compatible with both kinds of recoat material; other recoaters are suitable for the top-index material only. Our manual recoaters having an 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 to learn more.
Proof Tester Options – The PTR206, PTR206B, and PTR208 Fiber Recoaters have an integrated linear proof tester, which takes the fiber up to a predetermined load (20 N) and after that releases it. The linear proof tester uses uojthk same fiber holding blocks because the recoater and therefore the fiber will not need to be moved prior to testing. The PTR307 and PTR307B Fiber Recoaters come with a built-in rotary proof tester, which may 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 using the included handset or tablet controller, allowing an individual to pick parameters like the load, the speed at which the load is applied, as well as the hold time.
Inserts for Fiber Holding Blocks – As well as the above, we provide you with a number of inserts for use in the fiber holding blocks in the recoaters to be able to support a variety of Sheathing 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.
