FTTH Cable Production Line – Everything That Others Say..

Fiber proof testers are built to apply a set load to a fusion-spliced optical fiber so that you can test the effectiveness of the spliced fiber. Our Sheathing Line 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 multipurpose designs that are also capable of stripping, cleaning, cleaving, splicing, 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 a 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 immediately test a recoated fiber having a pre-determined load and figure out the long term reliability of the fiber. Because of their capability 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.

The process starts off with the fusion-spliced part of fiber being placed in the middle of the mold assembly (see image to the right). Once set in position, inserts inside the fiber blocks secure the spliced fiber set up. Recoat material is pumped in to the cavity then UV-cured. The recoated fiber may then be tested by pulling into 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 FTTH Cable Production Line features pneumatic control over 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 system is used to inject the recoat material into the mold cavity.

The PTR208 automatic recoater comes standard having a mold assembly for Ø430 µm coated fibers; For the manual recoaters (Item #s PTR206, PTR206B, PTR307, and PTR307B), the mold assembly comes separately so that customers can choose the best mold coating diameter for their application. Custom mold coating sizes can be found up to Ø900 µm. Pre-setting up the mold assembly in 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 for use during these recoaters. Recoaters with manual injection pumps (Item #s PTR206B and PTR307B) are compatible with both varieties of recoat material; all the other recoaters are appropriate for our prime-index material only. Our manual recoaters with the automatic injection system (Item #s PTR206 and PTR307) can be customized to work alongside the low- and-index recoat material; please contact Tech Support to learn more.

Proof Tester Options

The PTR206, PTR206B, and PTR208 Fiber Recoaters include a built-in linear proof tester, that takes 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 since the recoater and thus the fiber does not have to be moved before testing. The PTR307 and PTR307B Fiber Recoaters include Secondary Coating Line, which may perform both proof and tension tests (?89 N). One set 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 choose parameters like the load, the pace at fseejm the burden is applied, and the hold time.

Inserts for Fiber Holding Blocks

As well as the above, we offer a variety of inserts to be used within the fiber holding blocks in the recoaters to be able to support a wide range of fiber coating diameters. For recoaters with a rotary proof tester, the inserts are compatible with fiber coating diameters in a vary from 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.
