Fiber proof testers are built to use a set load to a fusion-spliced optical fiber so that you can test the effectiveness of the spliced fiber. Our Fiber Drawing Machine are available 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 which 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 some stripped fiber, offering more flexibility than 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 having 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 ideal for applications such as undersea optical fiber cables, submarine communication cabling, fiber lasers, or Distributed Bragg Reflector (DBR) lasers.
The process starts with the fusion-spliced part of fiber being placed in the middle of the mold assembly (see image to the right). Once set in position, inserts in the fiber blocks secure the spliced fiber in place. Recoat material is pumped to the cavity and then UV-cured. The recoated fiber may then be tested by pulling on 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 Fiber Drawing Machine features pneumatic control over 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 perfect for low-volume manufacturing or R&D applications. A computerized or manual volumetric dispensing pump and injection product is employed to inject the recoat material in to the mold cavity.
The PTR208 automatic recoater comes standard having a mold assembly for Ø430 µm coated fibers; For your manual recoaters (Item #s PTR206, PTR206B, PTR307, and PTR307B), the mold assembly is sold separately so that customers can choose the right mold coating diameter for his or her application. Custom mold coating sizes can be found as much as Ø900 µm. Pre-installing of the mold assembly on the factory is additionally 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 use during these recoaters. Recoaters with manual injection pumps (Item #s PTR206B and PTR307B) are compatible with both kinds of recoat material; all the other recoaters are suitable for our prime-index material only. Our manual recoaters having an automatic injection system (Item #s PTR206 and PTR307) may 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 incorporated linear proof tester, that takes the fiber as much as a predetermined load (20 N) and then releases it. The linear proof tester uses the same fiber holding blocks as the recoater and thus the fiber does not have to be moved just before testing. The PTR307 and PTR307B Fiber Recoaters have Optical Fiber Coloring Machine, which may 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 through the included handset or tablet controller, allowing the consumer to choose parameters such as the load, the rate at fseejm the stress is used, and also the hold time.
Inserts for Fiber Holding Blocks
In addition to the above, we provide a variety of inserts for use in the fiber holding blocks of the recoaters so that you can support a variety of fiber coating diameters. For recoaters having a rotary proof tester, the inserts are suitable for fiber coating diameters in a vary 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.
