Fiber proof testers are created to use a set load to FTTH cable production line in order to test the strength of the spliced fiber. Our fiber proof testers can be purchased 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. Choose from dedicated, standalone systems or multi-purpose designs that are also capable of stripping, cleaning, cleaving, splicing, and/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 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 figure out the long term reliability of the fiber. Due to their capability to restore a fusion-spliced fiber to near original condition, these systems are best for applications including undersea optical fiber cables, submarine communication cabling, fiber lasers, or Distributed Bragg Reflector (DBR) lasers.
This process starts with the fusion-spliced part of fiber being placed in the center of the mold assembly (see image off to the right). Once set in position, inserts within the fiber blocks secure the spliced fiber in position. Recoat material is pumped into the cavity and after that UV-cured. The recoated fiber can then be tested by pulling on it up to and including pre-determined load.
Recoater and Mold Assembly Options – Recoaters are available with either an automated or manual mold assembly. The automatic mold assembly features pneumatic control over the mold plates and is optimized for high-volume manufacturing applications. Manual mold assemblies, on the contrary, use hinged mold plates which provide more flexibility and are perfect 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 in to the mold cavity.
The PTR208 automatic recoater comes standard using a mold assembly for SZ stranding line; For our manual recoaters (Item #s PTR206, PTR206B, PTR307, and PTR307B), the mold assembly is sold separately in order that customers can choose the right mold coating diameter for their application. Custom mold coating sizes can be purchased approximately Ø900 µm. Pre-installing of the mold assembly on the factory is additionally 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 for use within these recoaters. Recoaters with manual injection pumps (Item #s PTR206B and PTR307B) are suitable for both types of recoat material; other recoaters are appropriate for the top-index material only. Our manual recoaters with the automatic injection system (Item #s PTR206 and PTR307) can be customized to do business with both the low- and-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 takes the fiber up to a predetermined load (20 N) and then releases it. The linear proof tester uses uojthk same fiber holding blocks because the recoater and therefore the fiber does not need to be moved before testing. The PTR307 and PTR307B Fiber Recoaters include an integrated rotary proof tester, which could perform both proof and tension tests (?89 N). One list of proof test grips is included; replacement proof test grips can be purchased below in packs of 10. Each testing process is fully programmable via the included handset or tablet controller, allowing the user to select parameters like the load, the rate where the burden is used, and the hold time.
Inserts for Fiber Holding Blocks – In addition to the above, we provide you with a variety of inserts for use in the fiber holding blocks in the recoaters to be able to support a variety of Fiber drawing machine. For recoaters having 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.
