Fiber proof testers are made to use a set load to Fiber drawing machine to be able to test the strength of the spliced fiber. Our fiber proof testers are available 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 multi-purpose designs which are also able to stripping, cleaning, cleaving, splicing, and 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 your stripped fiber, offering more flexibility when compared to 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 immediately test a recoated fiber with a pre-determined load and figure out the long term longevity of the fiber. Because of their capability to restore a fusion-spliced fiber to near original condition, these systems are best for applications like undersea optical fiber cables, submarine communication cabling, fiber lasers, or Distributed Bragg Reflector (DBR) lasers.
The procedure starts off with the fusion-spliced part of fiber being placed in the center of the mold assembly (see image to the correct). Once occur position, inserts inside the fiber blocks secure the spliced fiber in place. Recoat material is pumped in to the cavity and 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 automatic mold assembly features pneumatic control of the mold plates and it is optimized for high-volume manufacturing applications. Manual mold assemblies, on the other hand, use hinged mold plates that offer more flexibility and are ideal for low-volume manufacturing or R&D applications. An automated or manual volumetric dispensing pump and injection method is employed to inject the recoat material in to the mold cavity.
The PTR208 automatic recoater comes standard with a mold assembly for secondary coating line; For the manual recoaters (Item #s PTR206, PTR206B, PTR307, and PTR307B), the mold assembly is sold separately in order that customers can select the right mold coating diameter for his or her application. Custom mold coating sizes can be purchased approximately Ø900 µm. Pre-installation of the mold assembly at the factory can also be 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 use in these recoaters. Recoaters with manual injection pumps (Item #s PTR206B and PTR307B) are appropriate for both varieties of recoat material; all other recoaters are compatible with our prime-index material only. Our manual recoaters having an automatic injection system (Item #s PTR206 and PTR307) can be customized to do business with both low- and high-index recoat material; please contact Tech Support for more information.
Proof Tester Options – The PTR206, PTR206B, and PTR208 Fiber Recoaters have an integrated linear proof tester, that takes the fiber up to and including predetermined load (20 N) then releases it. The linear proof tester uses uojthk same fiber holding blocks because the recoater and thus the fiber fails to have to be moved just before testing. The PTR307 and PTR307B Fiber Recoaters come with 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 via the included handset or tablet controller, allowing the user to select parameters including the load, the speed at which the stress is applied, and the hold time.
Inserts for Fiber Holding Blocks – Along with the above, we provide you with a variety of inserts to be used within the fiber holding blocks from the recoaters so that you can support an array of optical fiber proof-testing machine. 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.
