This automatic optical fiber tensile testing system is ideal for operator skill independent use in production and laboratory settings. Two basic model configurations enable the user to pick between a setup for standard linear proof testing along with additional mandrels for rotary high strength testing.

The linear version is made for production proof testing with forces approximately 22 N. Motorized clamps with carefully designed rubber inserts be sure that the optical fiber ribbon machine is not damaged inside the testing process while simultaneously eliminating the need for another air supply. Amounts of pulling force, pulling speed and hold time are programmable and conveniently available to the operator from the built-in LCD touchscreen display control. Data from tests can be saved and accessed through the USB port or Ethernet interface.

Mandrels of the same design as in NYFORS’ optical fiber recoaters can easily be mounted on the proof tester inside the rotary high strength configuration. The fiber is wrapped across the two mandrels which support it with a special clamping mechanism. By doing this greater loads does apply on the fiber, enabling breaking strength tests under controlled circumstances.

Adjustable clamp positioning facilitates testing with all the highest force levels as well as testing of short fiber lengths. The compact and light weight design helps make the instrument easy to move around in a laboratory environment as well as integrate in a production work bench where space is at reduced. The equipment is really a compact and light-weight instrument ideal for testing the effectiveness of optical fibers up to 30 N. The machine is developed to meet all sorts of applications in which a strength test has to be performed.

The machine is made with the user in mind. The Fiber drawing machine is easily positioned in the guided linear clamps, and the testing starts automatically with a “One Touch” go button. The built-in microprocessor controls each of the important parameters such as pulling force, pulling speed and hold time. This permits for any completely controlled test every time.

The machine can be connected to an outside PC, which enables use of all programmable parameters and settings. The equipment is adapted to face-alone use or the integration into different subsystems. The device has an extensive capacity for logging and saving information including pulling force, pulling speed and fiber diameter and other parameters.

Two recoat injector configurations can be found. The PTR307 uses a computerized pump to inject the recoat material. The quantity of material dispensed through the automatic injector is controlled yourself through the top-mounted “Inject” button or programmed to the machine using the tablet controller. The PTR307B includes a manual recoat injection system that will require the user to manually dispense the recoat material to the mold cavity; a replacement injector for that PTR307B recoater is accessible below. Take note uojthk the automatic injector is simply compatible with high-index recoat material, as the manual injector is compatible with both low- and- index recoat material; they are both sold separately below. Please contact Tech Support for more information.

he manual injector may be mounted to compatible fiber recoaters using the 4-40 screws on the recoater housing (see photo to the correct). Utilize a 3/32″ hex key to secure the injector before use. To get in touch the PTRRRM for the recoater mold, tighten the connector at the end of the green plastic tubing, then loosen with a 1/4 consider permit rotation.

The injector is equipped with a distribution valve and 2-position selection lever for directing the flow of recoat material. A knurled dispensing screw with the internal plunger behaves as a syringe for the recoat material. To fill the syringe, point the lever downward (i.e., toward the recoat bottle), then rotate the knurled dispensing screw counterclockwise until it spins freely to fill the syringe (shown in the photo off to the right). Then, to inject the secondary coating line, point the lever horizontally (i.e., facing the knurled screw) and rotate the screw clockwise until near the end in the travel range is reached. Avoid bottoming the dispenser as this may damage the internal plunger; also be careful when re-engaging the threads to avoid cross threading the dispensing screw. Several fill/inject steps may be required until air is displaced inside the system. Use lens tissue and an acetone or alcohol cleaning answer to collect any excess recoat material that flows from your mold.
