Fiber proof testers are designed to use a set load to FTTH cable production line in order to test the potency of the spliced fiber. Our fiber proof testers can be found in both linear and rotary designs, for both 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 able to stripping, cleaning, cleaving, splicing, and 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 a stripped fiber, offering more flexibility when compared to 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 instantly test a recoated fiber using a pre-determined load and find out the long term longevity of the fiber. Due to their ability to restore a fusion-spliced fiber to near original condition, these systems are ideal for applications like undersea optical fiber cables, submarine communication cabling, fiber lasers, or Distributed Bragg Reflector (DBR) lasers.
The process begins with the fusion-spliced section of fiber being placed in the midst of the mold assembly (see image to the right). Once occur position, inserts inside the fiber blocks secure the spliced fiber set up. Recoat material is pumped into the cavity and after that UV-cured. The recoated fiber can then be tested by pulling onto it as much as a pre-determined load.
Recoater and Mold Assembly Options – Recoaters can be purchased with either an automatic or manual mold assembly. The automated mold assembly features pneumatic charge 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 provide more flexibility and are perfect for low-volume manufacturing or R&D applications. An automatic or manual volumetric dispensing pump and injection product is utilized to inject the recoat material into the mold cavity.
The PTR208 automatic recoater comes standard having a mold assembly for optical fiber coloring machine; 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 their application. Custom mold coating sizes are available up to Ø900 µm. Pre-installation of the mold assembly at the factory is additionally available. Contact Tech Support for additional info on custom molds or factory assembly.
We offer 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 kinds of recoat material; all 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 both the low- and high-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, that 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 as the recoater and therefore the fiber fails to must be moved 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 the consumer to choose parameters like the load, the speed in which the stress is applied, and the hold time.
Inserts for Fiber Holding Blocks – As well as the above, we provide many different inserts for use within the fiber holding blocks of the recoaters so that you can support a wide range of secondary coating line. For recoaters using a rotary proof tester, the inserts are suitable for fiber coating diameters in a vary from 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.
