Fiber Drawing Machine – Reasons To Read Much More About This Characteristic..

Fiber proof testers are built to use a set load to a fusion-spliced optical fiber so that you can test the potency of the spliced fiber. Our Secondary Coating Line can be found in both linear and rotary designs, both 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, 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 it to be handled and coiled with no damage to 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 find out the long-term longevity of the fiber. Due to their capability to restore a fusion-spliced fiber to near original condition, these systems are best for applications such as undersea optical fiber cables, submarine communication cabling, fiber lasers, or Distributed Bragg Reflector (DBR) lasers.

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

Recoater and Mold Assembly Options

Recoaters are available with either an automatic or manual mold assembly. The Optical Fiber Ribbon Machine features pneumatic charge of the mold plates and it is optimized for high-volume manufacturing applications. Manual mold assemblies, on the contrary, use hinged mold plates that offer more flexibility and are perfect for low-volume manufacturing or R&D applications. An automatic or manual volumetric dispensing pump and injection product is utilized to inject the recoat material into the mold cavity.

The PTR208 automatic recoater comes standard with a mold assembly for Ø430 µm coated fibers; For our manual recoaters (Item #s PTR206, PTR206B, PTR307, and PTR307B), the mold assembly is sold separately to ensure that customers can choose the right mold coating diameter for their application. Custom mold coating sizes are available approximately Ø900 µm. Pre-installing of the mold assembly at the factory can also be available. Contact Tech Support for more information on custom molds or factory assembly.

We offer both high-index (Item # AB950200) and low-index (Item # PC373) recoat materials to use within these recoaters. Recoaters with manual injection pumps (Item #s PTR206B and PTR307B) are compatible with both varieties of recoat material; all other recoaters are appropriate for our prime-index material only. Our manual recoaters with an automatic injection system (Item #s PTR206 and PTR307) could be customized to work alongside both low- and high-index recoat material; please contact Tech Support for additional information.

Proof Tester Options

The PTR206, PTR206B, and PTR208 Fiber Recoaters have a built-in linear proof tester, that can take the fiber as much as a predetermined load (20 N) and after that releases it. The linear proof tester uses the same fiber holding blocks because the recoater and so the fiber will not must be moved prior to testing. The PTR307 and PTR307B Fiber Recoaters have Sheathing Line, which could 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 an individual to choose parameters including the load, the speed at fseejm the burden is applied, as well as the hold time.

Inserts for Fiber Holding Blocks

As well as the above, we offer many different inserts to use inside the fiber holding blocks from the recoaters so that you can support a variety of fiber coating diameters. For recoaters having a rotary proof tester, the inserts are compatible with fiber coating diameters in a range between 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.
