Fiber proof testers are designed 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, for proof and tension testing. Fiber proof testers are available for single mode, multimode, and polarization-maintaining fibers. Pick from dedicated, standalone systems or multipurpose designs that are also capable of stripping, cleaning, cleaving, splicing, and 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 your stripped fiber, offering more flexibility when compared to 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 instantly test a recoated fiber using a pre-determined load and find out the long-term longevity of the fiber. Because of the capacity 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 procedure starts with the fusion-spliced section of fiber being placed in the middle of the mold assembly (see image off to the right). Once occur position, inserts in the fiber blocks secure the spliced fiber set up. Recoat material is pumped in to the cavity then UV-cured. The recoated fiber are able to be tested by pulling on it as much as a pre-determined load.

Recoater and Mold Assembly Options

Recoaters can be purchased with either an automatic or manual mold assembly. The SZ Stranding Line features pneumatic charge of the mold plates and is also optimized for top-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. A computerized or manual volumetric dispensing pump and injection product is utilized to inject the recoat material to 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 comes separately in order that customers can choose the best mold coating diameter for application. Custom mold coating sizes are available as much as Ø900 µm. Pre-setting up the mold assembly at the factory can also be available. Contact Tech Support to learn more about custom molds or factory assembly.

We provide 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 compatible with both types of recoat material; all other recoaters are suitable for the high-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 high-index recoat material; please contact Tech Support for additional information.

Proof Tester Options

The PTR206, PTR206B, and PTR208 Fiber Recoaters have an integrated linear proof tester, that can take the fiber up to a predetermined load (20 N) then releases it. The linear proof tester uses the identical fiber holding blocks because the recoater and therefore 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 set of proof test grips is included; replacement proof test grips can be purchased below in packs of 10. Each testing process is fully programmable using the included handset or tablet controller, allowing the consumer to choose parameters like the load, the pace at fseejm the stress is used, and the hold time.

Inserts for Fiber Holding Blocks

As well as the above, we provide you with a number of inserts to use within the fiber holding blocks in the recoaters so that you can support a wide range of fiber coating diameters. For recoaters using a rotary proof tester, the inserts are appropriate for fiber coating diameters in a range from 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.
