Fiber proof testers are made to use a set load to FTTH cable production line in order to test the strength of the spliced fiber. Our fiber proof testers can be found 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. Choose from dedicated, standalone systems or multi-purpose designs which are also competent at stripping, cleaning, cleaving, splicing, and recoating.
Fiber Recoaters with Proof Testers offer easy, integrated solutions to recoat and test fusion-spliced fibers. The fiber recoating process restores the buffer coating to some stripped fiber, offering more flexibility than a heat-shrink protection sleeve, enabling so that it is handled and coiled with no damage to the fusion-spliced section. The integrated linear or rotary proof tester allows users to instantly test a recoated fiber having a pre-determined load and determine the long-term longevity of the fiber. Due to their ability to restore a fusion-spliced fiber to near original condition, these systems are best for applications like undersea optical fiber cables, submarine communication cabling, fiber lasers, or Distributed Bragg Reflector (DBR) lasers.
The procedure starts 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 inside the fiber blocks secure the spliced fiber in place. Recoat material is pumped in to the cavity then UV-cured. The recoated fiber may then be tested by pulling into it up to a pre-determined load.
Recoater and Mold Assembly Options – Recoaters can be found with either an automated or manual mold assembly. The automated mold assembly features pneumatic control of the mold plates and it is optimized for high-volume manufacturing applications. Manual mold assemblies, on the other hand, use hinged mold plates which provide more flexibility and are best for low-volume manufacturing or R&D applications. An automatic or manual volumetric dispensing pump and injection system is employed to inject the recoat material into the mold cavity.
The PTR208 automatic recoater comes standard with a mold assembly for Fiber drawing machine; For our manual recoaters (Item #s PTR206, PTR206B, PTR307, and PTR307B), the mold assembly is sold separately so that customers can choose the best mold coating diameter for application. Custom mold coating sizes are available up to Ø900 µm. Pre-installation of the mold assembly in the factory can also be 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 the 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 work with both low- and-index recoat material; please contact Tech Support for additional information.
Proof Tester Options – The PTR206, PTR206B, and PTR208 Fiber Recoaters include an incorporated linear proof tester, that can take the fiber as much as a predetermined load (20 N) then releases it. The linear proof tester uses uojthk same fiber holding blocks as the recoater and therefore the fiber does not need to be moved prior to testing. The PTR307 and PTR307B Fiber Recoaters have an integrated rotary proof tester, which can 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 through the included handset or tablet controller, allowing the consumer to choose parameters like the load, the speed where the burden is used, and also the hold time.
Inserts for Fiber Holding Blocks – As well as the above, we offer a number of inserts to be used inside the fiber holding blocks from the recoaters to be able to support an array of Sheathing line. 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 with a linear proof tester, the inserts cover a range for fiber coatings from Ø250 µm to Ø900 µm.
