Fiber proof testers are made to apply a set load to Sheathing line to be able to test the strength of the spliced fiber. Our fiber proof testers can be found 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 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 when compared to 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 using a pre-determined load and determine 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 portion of fiber being placed in the middle of the mold assembly (see image to the right). Once placed in position, inserts within the fiber blocks secure the spliced fiber in position. Recoat material is pumped into the cavity then UV-cured. The recoated fiber are able to be tested by pulling onto it up to and including pre-determined load.
Recoater and Mold Assembly Options – Recoaters can be purchased with either an automatic or manual mold assembly. The automated mold assembly features pneumatic charge of the mold plates and it is optimized for high-volume manufacturing applications. Manual mold assemblies, on the other hand, use hinged mold plates that offer more flexibility and are ideal for low-volume manufacturing or R&D applications. A computerized or manual volumetric dispensing pump and injection system is utilized to inject the recoat material into the mold cavity.
The PTR208 automatic recoater comes standard having a mold assembly for SZ stranding line; For our manual recoaters (Item #s PTR206, PTR206B, PTR307, and PTR307B), the mold assembly is sold separately in order that customers can choose the right mold coating diameter for their application. Custom mold coating sizes can be purchased as much as Ø900 µm. Pre-installation of the mold assembly at the factory is also available. Contact Tech Support for additional info on custom molds or factory assembly.
We provide both high-index (Item # AB950200) and low-index (Item # PC373) recoat materials for use during these recoaters. Recoaters with manual injection pumps (Item #s PTR206B and PTR307B) are compatible with both varieties of recoat material; all other recoaters are compatible with the high-index material only. Our manual recoaters with the automatic injection system (Item #s PTR206 and PTR307) may be customized to work with both the low- and-index recoat material; please contact Tech Support to learn more.
Proof Tester Options – The PTR206, PTR206B, and PTR208 Fiber Recoaters include an incorporated linear proof tester, that can take the fiber up to a predetermined load (20 N) then releases it. The linear proof tester uses uojthk same fiber holding blocks as the recoater and thus the fiber does not need to be moved prior to testing. The PTR307 and PTR307B Fiber Recoaters come with an integrated rotary proof tester, which may perform both proof and tension tests (?89 N). One group of proof test grips is included; replacement proof test grips are available below in packs of 10. Each testing process is fully programmable via the included handset or tablet controller, allowing the user to pick parameters like the load, the speed at which the burden is used, and the hold time.
Inserts for Fiber Holding Blocks – As well as the above, we provide you with many different inserts to be used in the fiber holding blocks in the recoaters so that you can support an array of Secondary coating line. For recoaters using a rotary proof tester, the inserts are appropriate 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.
