Fiber proof testers are built to use a set load to a fusion-spliced optical fiber to be able to test the potency of the spliced fiber. Our SZ Stranding Line 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. Select from dedicated, standalone systems or multipurpose designs which are also capable of stripping, cleaning, cleaving, splicing, and/or recoating.
Fiber Recoaters with Proof Testers offer easy, integrated solutions to recoat and test fusion-spliced fibers. The fiber recoating process restores the buffer coating to a stripped fiber, offering more flexibility 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 with a pre-determined load and determine the long-term longevity of the fiber. Because of the 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 middle of the mold assembly (see image to the correct). Once set in position, inserts in the fiber blocks secure the spliced fiber in place. Recoat material is pumped to the cavity and after that 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 purchased with either an automatic or manual mold assembly. The SZ Stranding Line features pneumatic charge of the mold plates and it is optimized for high-volume manufacturing applications. Manual mold assemblies, on the contrary, use hinged mold plates which provide more flexibility and are best for low-volume manufacturing or R&D applications. An automatic 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 Ø430 µm coated fibers; For the manual recoaters (Item #s PTR206, PTR206B, PTR307, and PTR307B), the mold assembly comes separately so that customers can choose the best mold coating diameter for his or her application. Custom mold coating sizes can be purchased up to Ø900 µm. Pre-installation of the mold assembly on the factory is additionally 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 suitable for both kinds of recoat material; all the other recoaters are appropriate for the top-index material only. Our manual recoaters with the automatic injection system (Item #s PTR206 and PTR307) could be customized to work alongside both the low- and high-index recoat material; please contact Tech Support for more information.
Proof Tester Options
The PTR206, PTR206B, and PTR208 Fiber Recoaters have a built-in linear proof tester, that takes the fiber up to and including predetermined load (20 N) and after that releases it. The linear proof tester uses the same fiber holding blocks because the recoater and therefore the fiber will not must be moved just before testing. The PTR307 and PTR307B Fiber Recoaters come with Optical Fiber Coloring Machine, which can perform both proof and tension tests (?89 N). One list 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 like the load, the rate at fseejm the burden is applied, as well as the hold time.
Inserts for Fiber Holding Blocks
In addition to the above, we provide a number of inserts to be used inside the fiber holding blocks in the recoaters so that you can support a variety of fiber coating diameters. For recoaters using a rotary proof tester, the inserts are compatible with fiber coating diameters in a vary 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.
