Fiber proof testers are built to use a set load to a fusion-spliced optical fiber in order to test the strength of the spliced fiber. Our FTTH Cable Production Line can be found 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 multipurpose designs which are also able to stripping, cleaning, cleaving, splicing, 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 than a heat-shrink protection sleeve, enabling so that it is handled and coiled with no damage to the fusion-spliced section. The integrated linear or rotary proof tester allows users to immediately test a recoated fiber using a pre-determined load and figure out the long-term reliability of the fiber. Because of their 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 starts with the fusion-spliced part of fiber being placed in the center of the mold assembly (see image to the right). Once occur position, inserts inside the fiber blocks secure the spliced fiber in place. Recoat material is pumped to the cavity then UV-cured. The recoated fiber can then be tested by pulling onto it up to and including pre-determined load.
Recoater and Mold Assembly Options
Recoaters are available with either an automatic or manual mold assembly. The Optical Fiber Coloring Machine features pneumatic control over 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 best 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 to the mold cavity.
The PTR208 automatic recoater comes standard using a mold assembly for Ø430 µm coated fibers; For your manual recoaters (Item #s PTR206, PTR206B, PTR307, and PTR307B), the mold assembly is sold separately so that customers can choose the right mold coating diameter for application. Custom mold coating sizes can be found as much as Ø900 µm. Pre-installing of the mold assembly on the factory is additionally 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 to use during these recoaters. Recoaters with manual injection pumps (Item #s PTR206B and PTR307B) are suitable for both types of recoat material; other recoaters are compatible with the top-index material only. Our manual recoaters with the automatic injection system (Item #s PTR206 and PTR307) may be customized to work alongside 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 a built-in linear proof tester, that can take the fiber as much as a predetermined load (20 N) and then releases it. The linear proof tester uses exactly the same fiber holding blocks as the recoater and therefore the fiber fails to have to be moved prior to testing. The PTR307 and PTR307B Fiber Recoaters come with Secondary Coating Line, which can perform both proof and tension tests (?89 N). One list 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 the user to choose parameters including the load, the speed at fseejm 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 from the recoaters to be able to support a variety of fiber coating diameters. For recoaters with a rotary proof tester, the inserts are compatible with fiber coating diameters in a range between 125 µm to 900 µm. For recoaters using a linear proof tester, the inserts cover a range for fiber coatings from Ø250 µm to Ø900 µm.
