Fiber proof testers are made to apply a set load to SZ stranding line in order to test the effectiveness 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 multipurpose designs that are also able to 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 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 having a pre-determined load and figure out the long-term longevity of the fiber. Because of their 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 begins 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 within the fiber blocks secure the spliced fiber in place. Recoat material is pumped in to the cavity then UV-cured. The recoated fiber can then be tested by pulling onto it up to a pre-determined load.

Recoater and Mold Assembly Options – Recoaters can be found with either an automated or manual mold assembly. The automated mold assembly features pneumatic control of the mold plates and is optimized for top-volume manufacturing applications. Manual mold assemblies, on the other hand, use hinged mold plates which provide more flexibility and are best 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 proof-testing machine; For your 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 application. Custom mold coating sizes can be found approximately Ø900 µm. Pre-setting up the mold assembly on the factory can also be available. Contact Tech Support for more information on custom molds or factory assembly.

We provide you with 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 appropriate for both kinds of recoat material; other recoaters are suitable for our prime-index material only. Our manual recoaters having an automatic injection system (Item #s PTR206 and PTR307) could 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 have an integrated linear proof tester, which takes the fiber up to a predetermined load (20 N) and then releases it. The linear proof tester uses uojthk same fiber holding blocks since the recoater and thus the fiber does not must be moved prior to testing. The PTR307 and PTR307B Fiber Recoaters have a built-in rotary proof tester, which may perform both proof and tension tests (?89 N). One list 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 consumer to choose parameters such as the load, the pace where the burden is used, and also the hold time.

Inserts for Fiber Holding Blocks – As well as the above, we offer a variety of inserts to use within the fiber holding blocks from the recoaters to be able to support a wide range of Sheathing 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.
