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, for both 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 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 compared to 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 immediately test a recoated fiber having a pre-determined load and find out the long-term reliability of the fiber. Because of the ability 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 part of fiber being placed in the center of the mold assembly (see image to the correct). Once occur position, inserts inside the fiber blocks secure the spliced fiber set up. Recoat material is pumped to the cavity and then UV-cured. The recoated fiber may then be tested by pulling into it up to a pre-determined load.
Recoater and Mold Assembly Options
Recoaters are available with either an automated or manual mold assembly. The Optical Fiber Proof-Testing Machine features pneumatic control of the mold plates and is also optimized for high-volume manufacturing applications. Manual mold assemblies, on the other hand, use hinged mold plates that offer more flexibility and are best for low-volume manufacturing or R&D applications. A computerized or manual volumetric dispensing pump and injection method is used to inject the recoat material to 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 comes separately in order that customers can choose the best mold coating diameter for 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 for more information on custom molds or factory assembly.
We provide both high-index (Item # AB950200) and low-index (Item # PC373) recoat materials to be used in these recoaters. Recoaters with manual injection pumps (Item #s PTR206B and PTR307B) are appropriate for both types of recoat material; other recoaters are compatible with the high-index material only. Our manual recoaters with an automatic injection system (Item #s PTR206 and PTR307) could be customized to work alongside both low- and-index recoat material; please contact Tech Support for more information.
Proof Tester Options
The PTR206, PTR206B, and PTR208 Fiber Recoaters come with an incorporated linear proof tester, that takes the fiber as much as a predetermined load (20 N) and after that releases it. The linear proof tester uses the same fiber holding blocks as the recoater and thus the fiber fails to have to be moved just before testing. The PTR307 and PTR307B Fiber Recoaters come with Optical Fiber Ribbon Machine, which may perform both proof and tension tests (?89 N). One set of proof test grips is included; replacement proof test grips are available below in packs of 10. Each testing process is fully programmable using the included handset or tablet controller, allowing an individual to pick parameters like the load, the speed at fseejm the stress is applied, as well as the hold time.
Inserts for Fiber Holding Blocks
Along with the above, we provide many different inserts for use in the fiber holding blocks of the recoaters so that you can support a wide range of fiber coating diameters. For recoaters having a rotary proof tester, the inserts are appropriate 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.
