Fiber proof testers are designed to use a set load to a fusion-spliced optical fiber in order to test the effectiveness of the spliced fiber. Our Secondary Coating Line are available 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. Pick 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 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 immediately test a recoated fiber having a pre-determined load and figure out the long term reliability of the fiber. Due to their 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.
This process begins with the fusion-spliced portion of fiber being placed in the center of the mold assembly (see image off to the right). Once placed in position, inserts inside the fiber blocks secure the spliced fiber set up. Recoat material is pumped in to the cavity and then UV-cured. The recoated fiber may then be tested by pulling onto 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 Optical Fiber Proof-Testing 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 that offer 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 our 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 application. Custom mold coating sizes can be purchased as much as Ø900 µm. Pre-installing of the mold assembly at the factory can also be available. Contact Tech Support for additional info on 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 suitable for both varieties 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 do business with both low- and high-index recoat material; please contact Tech Support to learn more.
Proof Tester Options
The PTR206, PTR206B, and PTR208 Fiber Recoaters have an integrated linear proof tester, which takes the fiber as much as a predetermined load (20 N) and after that releases it. The linear proof tester uses the identical fiber holding blocks since the recoater and so the fiber fails to must be moved before testing. The PTR307 and PTR307B Fiber Recoaters include Secondary Coating Line, which can perform both proof and tension tests (?89 N). One set of proof test grips is included; replacement proof test grips can be purchased below in packs of 10. Each testing process is fully programmable through the included handset or tablet controller, allowing the consumer to select parameters including the load, the speed at fseejm the burden is used, as well as the hold time.
Inserts for Fiber Holding Blocks
Along with the above, we offer a number of inserts for use inside the fiber holding blocks in 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 between 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.
