Fiber proof testers are built to use a set load to a fusion-spliced optical fiber in order to test the potency of the spliced fiber. Our Optical Fiber Proof-Testing 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. Pick from dedicated, standalone systems or multipurpose designs which are also capable of stripping, cleaning, cleaving, splicing, and 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 using a pre-determined load and determine the long term longevity of the fiber. Because of their capacity 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.
This process begins with the fusion-spliced portion of fiber being placed in the middle of the mold assembly (see image off to the right). Once set in position, inserts inside the fiber blocks secure the spliced fiber in position. Recoat material is pumped to the cavity and then UV-cured. The recoated fiber may then be tested by pulling onto it as much as a pre-determined load.
Recoater and Mold Assembly Options
Recoaters are available with either an automatic or manual mold assembly. The Fiber Drawing Machine features pneumatic charge of the mold plates and is optimized for top-volume manufacturing applications. Manual mold assemblies, on the contrary, use hinged mold plates which provide more flexibility and are ideal 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 into the mold cavity.
The PTR208 automatic recoater comes standard using 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 select the right mold coating diameter for their application. Custom mold coating sizes can be found up to Ø900 µm. Pre-installing of the mold assembly in the factory is additionally 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 appropriate for the high-index material only. Our manual recoaters with the automatic injection system (Item #s PTR206 and PTR307) could be customized to work alongside the low- and high-index recoat material; please contact Tech Support for more information.
Proof Tester Options
The PTR206, PTR206B, and PTR208 Fiber Recoaters have a built-in linear proof tester, which takes the fiber up to and including 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 must be moved prior to testing. The PTR307 and PTR307B Fiber Recoaters come with FTTH Cable Production Line, which can perform both proof and tension tests (?89 N). One list of proof test grips is included; replacement proof test grips can be purchased below in packs of 10. Each testing process is fully programmable using the included handset or tablet controller, allowing an individual to select parameters such as the load, the pace at fseejm the burden is applied, and also the hold time.
Inserts for Fiber Holding Blocks
In addition to the above, we provide many different inserts to use inside the fiber holding blocks from the recoaters in order to support a wide range of fiber coating diameters. For recoaters with 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.
