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 Optical Fiber Proof-Testing Machine can be purchased in both linear and rotary designs, for 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 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 your stripped fiber, offering more flexibility compared to a heat-shrink protection sleeve, enabling so 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 with a pre-determined load and determine the long term reliability of the fiber. Due to their capability to restore a fusion-spliced fiber to near original condition, these systems are ideal for applications including undersea optical fiber cables, submarine communication cabling, fiber lasers, or Distributed Bragg Reflector (DBR) lasers.
The process starts off with the fusion-spliced part of fiber being placed in the midst of the mold assembly (see image off to the right). Once placed in position, inserts within the fiber blocks secure the spliced fiber in place. Recoat material is pumped to the cavity then UV-cured. The recoated fiber are able to be tested by pulling into it up to a pre-determined load.
Recoater and Mold Assembly Options
Recoaters can be found with either a computerized or manual mold assembly. The Optical Fiber Ribbon Machine features pneumatic control of the mold plates and is optimized for top-volume manufacturing applications. Manual mold assemblies, on the contrary, 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 with a mold assembly for Ø430 µm coated fibers; For our manual recoaters (Item #s PTR206, PTR206B, PTR307, and PTR307B), the mold assembly is sold separately in order 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 also 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 for use during these recoaters. Recoaters with manual injection pumps (Item #s PTR206B and PTR307B) are appropriate for both varieties of recoat material; all other recoaters are compatible with the top-index material only. Our manual recoaters with an automatic injection system (Item #s PTR206 and PTR307) can be customized to do business with the low- and-index recoat material; please contact Tech Support for additional information.
Proof Tester Options
The PTR206, PTR206B, and PTR208 Fiber Recoaters include 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 identical fiber holding blocks as the recoater and so the fiber will not must be moved prior to testing. The PTR307 and PTR307B Fiber Recoaters come with Optical Fiber Coloring Machine, which may perform both proof and tension tests (?89 N). One group 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 such as the load, the pace at fseejm the load is applied, and also the hold time.
Inserts for Fiber Holding Blocks
In addition to the above, we provide you with a variety of inserts for use inside the fiber holding blocks of the recoaters in order to support an array of fiber coating diameters. For recoaters having a rotary proof tester, the inserts are suitable for fiber coating diameters in a range from 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.
