Fiber proof testers are designed to use a set load to Sheathing line to be able to test the strength of the spliced fiber. Our fiber proof testers can be purchased in both linear and rotary designs, 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 capable of stripping, cleaning, cleaving, splicing, or 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 compared to a heat-shrink protection sleeve, enabling so 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. Due to their capability to restore a fusion-spliced fiber to near original condition, these systems are ideal for applications such as undersea optical fiber cables, submarine communication cabling, fiber lasers, or Distributed Bragg Reflector (DBR) lasers.
The process starts off with the fusion-spliced part of fiber being placed in the midst of the mold assembly (see image to the right). Once placed in position, inserts inside the fiber blocks secure the spliced fiber in place. Recoat material is pumped into the cavity and then UV-cured. The recoated fiber are able to be tested by pulling into it up to and including pre-determined load.
Recoater and Mold Assembly Options – Recoaters can be purchased with either an automatic or manual mold assembly. The automatic mold assembly features pneumatic control over the mold plates and is also optimized for high-volume manufacturing applications. Manual mold assemblies, on the other hand, use hinged mold plates that provide more flexibility and are ideal for low-volume manufacturing or R&D applications. A computerized or manual volumetric dispensing pump and injection system is used to inject the recoat material into the mold cavity.
The PTR208 automatic recoater comes standard using a mold assembly for optical fiber coloring machine; For the manual recoaters (Item #s PTR206, PTR206B, PTR307, and PTR307B), the mold assembly comes separately so that customers can choose the best mold coating diameter for application. Custom mold coating sizes are available as much as Ø900 µm. Pre-installing of the mold assembly at the factory is also available. Contact Tech Support for more information on custom molds or factory assembly.
We offer both high-index (Item # AB950200) and low-index (Item # PC373) recoat materials to be used during these recoaters. Recoaters with manual injection pumps (Item #s PTR206B and PTR307B) are appropriate for both types of recoat material; all the other recoaters are appropriate for the high-index material only. Our manual recoaters having an automatic injection system (Item #s PTR206 and PTR307) can be customized to work alongside the low- and-index recoat material; please contact Tech Support for additional information.
Proof Tester Options – The PTR206, PTR206B, and PTR208 Fiber Recoaters have a built-in linear proof tester, which takes 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 since the recoater and thus the fiber does not need to be moved just before testing. The PTR307 and PTR307B Fiber Recoaters have an integrated 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 choose parameters including the load, the rate where the stress is used, and the hold time.
Inserts for Fiber Holding Blocks – In addition to the above, we offer a number of inserts to use inside the fiber holding blocks of the recoaters to be able to support a variety of Fiber drawing machine. For recoaters having a rotary proof tester, the inserts are suitable for fiber coating diameters in a range between 125 µm to 900 µm. For recoaters with a linear proof tester, the inserts cover a range for fiber coatings from Ø250 µm to Ø900 µm.
