Fiber proof testers are made to apply a set load to Fiber drawing machine to be able to test the strength of the spliced fiber. Our fiber proof testers 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 competent at stripping, cleaning, cleaving, splicing, or 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 some stripped fiber, offering more flexibility than a heat-shrink protection sleeve, enabling that it is 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 having a pre-determined load and find out the long-term reliability of the fiber. Due to their capacity 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 process begins with the fusion-spliced portion of fiber being placed in the center of the mold assembly (see image off to the right). Once set in position, inserts in the fiber blocks secure the spliced fiber in place. Recoat material is pumped to the cavity and then UV-cured. The recoated fiber are able to be tested by pulling onto 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 charge of the mold plates and is optimized for top-volume manufacturing applications. Manual mold assemblies, on the contrary, use hinged mold plates which provide more flexibility and are perfect for low-volume manufacturing or R&D applications. An automated or manual volumetric dispensing pump and injection system is utilized to inject the recoat material in to the mold cavity.
The PTR208 automatic recoater comes standard having a mold assembly for optical fiber coloring machine; For the manual recoaters (Item #s PTR206, PTR206B, PTR307, and PTR307B), the mold assembly is sold separately so that customers can select the right mold coating diameter for application. Custom mold coating sizes can be purchased up to Ø900 µm. Pre-installation of the mold assembly in the factory can also be available. Contact Tech Support for more information on custom molds or factory assembly.
We provide you with 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 appropriate for both varieties of recoat material; other recoaters are appropriate for the high-index material only. Our manual recoaters with the automatic injection system (Item #s PTR206 and PTR307) could be customized to work alongside the low- and high-index recoat material; please contact Tech Support for more information.
Proof Tester Options – The PTR206, PTR206B, and PTR208 Fiber Recoaters come with an incorporated linear proof tester, that takes the fiber up to and including predetermined load (20 N) and then releases it. The linear proof tester uses uojthk same fiber holding blocks since the recoater and thus the fiber fails to must be moved prior to testing. The PTR307 and PTR307B Fiber Recoaters include an incorporated rotary proof tester, which could 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 via the included handset or tablet controller, allowing the consumer to choose parameters like the load, the speed at which the load is applied, and also the hold time.
Inserts for Fiber Holding Blocks – As well as the above, we offer a number of inserts to use inside the fiber holding blocks in the recoaters in order to support a wide range of optical fiber coloring machine. For recoaters having a rotary proof tester, the inserts are appropriate for fiber coating diameters in a range 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.
