Secondary Coating Line – Surf To Our Site Today To Look For More Advice..

Fiber proof testers are designed to use a set load to secondary coating line to be able to test the effectiveness of the spliced fiber. Our fiber proof testers are available 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. Select from dedicated, standalone systems or multi-purpose designs which are also capable of stripping, cleaning, cleaving, splicing, and/or recoating.

Fiber Recoaters with Proof Testers offer easy, integrated answers to recoat and test fusion-spliced fibers. The fiber recoating process restores the buffer coating to some stripped fiber, offering more flexibility 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 figure out 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 like undersea optical fiber cables, submarine communication cabling, fiber lasers, or Distributed Bragg Reflector (DBR) lasers.

This process starts with the fusion-spliced section of fiber being placed in the midst of the mold assembly (see image to the right). Once occur position, inserts inside the fiber blocks secure the spliced fiber set up. Recoat material is pumped to the cavity and after that UV-cured. The recoated fiber can then be tested by pulling into it up to a pre-determined load.

Recoater and Mold Assembly Options – Recoaters are available with either an automated or manual mold assembly. The automatic mold assembly features pneumatic control over the mold plates and it is optimized for top-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 comes separately in order that customers can select the right mold coating diameter for application. Custom mold coating sizes are available approximately Ø900 µm. Pre-installing of the mold assembly at the factory is additionally available. Contact Tech Support to learn more about custom molds or factory assembly.

We offer both high-index (Item # AB950200) and low-index (Item # PC373) recoat materials to be used in these recoaters. Recoaters with manual injection pumps (Item #s PTR206B and PTR307B) are suitable for both kinds of recoat material; all the other recoaters are appropriate for the high-index material only. Our manual recoaters having an automatic injection system (Item #s PTR206 and PTR307) can be customized to work 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 include an incorporated linear proof tester, that takes the fiber up to a predetermined load (20 N) and then releases it. The linear proof tester uses uojthk same fiber holding blocks as the recoater and thus the fiber fails to need to be moved just before testing. The PTR307 and PTR307B Fiber Recoaters have 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 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 pick parameters such as the load, the rate at which the stress is applied, and also the hold time.

Inserts for Fiber Holding Blocks – Along with the above, we offer a variety of inserts to use within the fiber holding blocks of the recoaters in order to support a wide range of Sheathing line. For recoaters with a rotary proof tester, the inserts are appropriate for fiber coating diameters in a range 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.
