Fiber proof testers are designed to use a set load to a fusion-spliced optical fiber to be able to test the potency of the spliced fiber. Our Fiber Drawing Machine 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 capable of stripping, cleaning, cleaving, splicing, or 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 than a heat-shrink protection sleeve, enabling that it is handled and coiled with no damage to 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 figure out the long-term reliability of the fiber. Because of the capability to restore a fusion-spliced fiber to near original condition, these systems are best for applications such as undersea optical fiber cables, submarine communication cabling, fiber lasers, or Distributed Bragg Reflector (DBR) lasers.
The procedure starts off with the fusion-spliced section 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 set up. Recoat material is pumped into the cavity then UV-cured. The recoated fiber may then be tested by pulling into 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 Fiber Drawing Machine features pneumatic charge of the mold plates and is optimized for high-volume manufacturing applications. Manual mold assemblies, on the other hand, use hinged mold plates that offer more flexibility and are ideal for low-volume manufacturing or R&D applications. A computerized or manual volumetric dispensing pump and injection method is utilized to inject the recoat material into the mold cavity.
The PTR208 automatic recoater comes standard having a mold assembly for Ø430 µm coated fibers; For the manual recoaters (Item #s PTR206, PTR206B, PTR307, and PTR307B), the mold assembly is sold separately so that customers can choose the best mold coating diameter for their application. Custom mold coating sizes can be purchased up to Ø900 µm. Pre-installing of the mold assembly on the factory can also be available. Contact Tech Support to learn more about custom molds or factory assembly.
We offer both high-index (Item # AB950200) and low-index (Item # PC373) recoat materials to be used during these recoaters. Recoaters with manual injection pumps (Item #s PTR206B and PTR307B) are appropriate for both varieties of recoat material; all the other recoaters are appropriate for the top-index material only. Our manual recoaters having an automatic injection system (Item #s PTR206 and PTR307) could be customized to work alongside the low- and-index recoat material; please contact Tech Support for more information.
Proof Tester Options
The PTR206, PTR206B, and PTR208 Fiber Recoaters have an integrated linear proof tester, that takes the fiber up to a predetermined load (20 N) and after that releases it. The linear proof tester uses the same fiber holding blocks since the recoater and therefore the fiber does not need to be moved just before testing. The PTR307 and PTR307B Fiber Recoaters have Secondary Coating Line, which could 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 consumer to choose parameters like the load, the speed at fseejm the burden is applied, and also the hold time.
Inserts for Fiber Holding Blocks
As well as the above, we provide a variety of inserts for use in the fiber holding blocks of the recoaters to be able to support a wide range of fiber coating diameters. For recoaters with a rotary proof tester, the inserts are appropriate for fiber coating diameters in a range between 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.
