Fiber proof testers are designed to apply a set load to optical fiber ribbon machine to be able to test the potency of the spliced fiber. Our fiber proof testers 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. Select from dedicated, standalone systems or multipurpose designs that are also able to 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 your stripped fiber, offering more flexibility than a heat-shrink protection sleeve, enabling that it is handled and coiled without damaging the fusion-spliced section. The integrated linear or rotary proof tester allows users to right away test a recoated fiber having a pre-determined load and figure 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 perfect for applications including undersea optical fiber cables, submarine communication cabling, fiber lasers, or Distributed Bragg Reflector (DBR) lasers.
This process starts off with the fusion-spliced part 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 in place. Recoat material is pumped into the cavity and after that UV-cured. The recoated fiber can 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 automatic or manual mold assembly. The automatic mold assembly features pneumatic control of the mold plates and is optimized for high-volume manufacturing applications. Manual mold assemblies, on the other hand, 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 system is used to inject the recoat material to the mold cavity.
The PTR208 automatic recoater comes standard with a mold assembly for optical fiber coloring machine; For our 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 application. Custom mold coating sizes can be purchased approximately Ø900 µm. Pre-installing of the mold assembly in the factory is also available. Contact Tech Support for more information 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 during these recoaters. Recoaters with manual injection pumps (Item #s PTR206B and PTR307B) are compatible with both types of recoat material; all the other recoaters are suitable for the high-index material only. Our manual recoaters with an automatic injection system (Item #s PTR206 and PTR307) may be customized to work with both the low- and high-index recoat material; please contact Tech Support for additional information.
Proof Tester Options – The PTR206, PTR206B, and PTR208 Fiber Recoaters have an incorporated linear proof tester, that can take the fiber up to a predetermined load (20 N) and after that releases it. The linear proof tester uses uojthk same fiber holding blocks as the recoater and thus the fiber will not need to be moved just before testing. The PTR307 and PTR307B Fiber Recoaters include an incorporated rotary proof tester, which may perform both proof and tension tests (?89 N). One list of proof test grips is included; replacement proof test grips can be found below in packs of 10. Each testing process is fully programmable using the included handset or tablet controller, allowing the consumer to choose parameters such as the load, the speed where the load is applied, and also the hold time.
Inserts for Fiber Holding Blocks – As well as the above, we offer many different inserts to be used within the fiber holding blocks in the recoaters to be able to support an array of secondary coating line. For recoaters using a rotary proof tester, the inserts are suitable for fiber coating diameters in a vary from 125 µm to 900 µm. For recoaters having a linear proof tester, the inserts cover a range for fiber coatings from Ø250 µm to Ø900 µm.
