Fiber proof testers are created to apply a set load to SZ stranding line in order to test the strength 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 multipurpose designs that are also capable of 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 when compared to 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 having a pre-determined load and determine the long term longevity of the fiber. Because of the capacity 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.
This process starts off with the fusion-spliced section of fiber being placed in the middle of the mold assembly (see image to the correct). Once occur position, inserts in the fiber blocks secure the spliced fiber set up. Recoat material is pumped to the cavity and then 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 can be found 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 which provide more flexibility and are ideal for low-volume manufacturing or R&D applications. An automated or manual volumetric dispensing pump and injection method is used to inject the recoat material into the mold cavity.
The PTR208 automatic recoater comes standard using a mold assembly for optical fiber ribbon machine; For our manual recoaters (Item #s PTR206, PTR206B, PTR307, and PTR307B), the mold assembly comes separately so that customers can choose the right mold coating diameter for his or her application. Custom mold coating sizes can be purchased up to Ø900 µm. Pre-setting up the mold assembly in the factory is also 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 for use in 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 high-index material only. Our manual recoaters with the automatic injection system (Item #s PTR206 and PTR307) may be customized to work with 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 come with an incorporated linear proof tester, which takes the fiber as much as a predetermined load (20 N) then releases it. The linear proof tester uses uojthk same fiber holding blocks as the recoater and therefore the fiber will not need to be moved just before testing. The PTR307 and PTR307B Fiber Recoaters come with an integrated rotary proof tester, which can perform both proof and tension tests (?89 N). One set of proof test grips is included; replacement proof test grips can be found below in packs of 10. Each testing process is fully programmable via the included handset or tablet controller, allowing the user to pick parameters like the load, the rate where the stress is applied, as well as the hold time.
Inserts for Fiber Holding Blocks – In addition to the above, we offer a variety of inserts for use in the fiber holding blocks from the recoaters in order to support an array of Secondary coating line. 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.
