Fiber proof testers are designed to use a set load to a fusion-spliced optical fiber to be able to test the strength of the spliced fiber. Our SZ Stranding Line 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. Choose 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 solutions 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 so that it is 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 determine the long term longevity of the fiber. Due to their ability 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 begins with the fusion-spliced section of fiber being placed in the midst of the mold assembly (see image off to the right). Once occur 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 may then be tested by pulling onto it up to a pre-determined load.
Recoater and Mold Assembly Options
Recoaters can be found with either an automated or manual mold assembly. The Fiber Drawing Machine features pneumatic control over the mold plates and is optimized for high-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 automated or manual volumetric dispensing pump and injection method 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 comes separately to ensure that customers can select the right mold coating diameter for application. Custom mold coating sizes can be purchased as much as Ø900 µm. Pre-setting up the mold assembly in the factory is also available. Contact Tech Support for additional info on custom molds or factory assembly.
We provide you with both high-index (Item # AB950200) and low-index (Item # PC373) recoat materials to be used within these recoaters. Recoaters with manual injection pumps (Item #s PTR206B and PTR307B) are appropriate for both types of recoat material; all other recoaters are compatible with the top-index material only. Our manual recoaters having an automatic injection system (Item #s PTR206 and PTR307) could be customized to do business with both 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 since the recoater and thus the fiber will not 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 through the included handset or tablet controller, allowing the consumer to pick parameters such as the load, the speed at fseejm the stress is applied, as well as the hold time.
Inserts for Fiber Holding Blocks
In addition to the above, we provide you with a variety of inserts to use within the fiber holding blocks from the recoaters in order to support an array of fiber coating diameters. For recoaters using a rotary proof tester, the inserts are compatible with 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.
