This automatic optical fiber tensile testing system is ideal for operator skill independent use in production and laboratory options. Two basic model configurations allow the user to choose between a set up 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 as much as 22 N. Motorized clamps with carefully designed rubber inserts ensure that the Fiber drawing machine is not really damaged inside the testing process while simultaneously eliminating the requirement for an external air supply. Degrees of pulling force, pulling speed and hold time are programmable and conveniently accessible to the operator with the built-in LCD touch-screen control. Data from tests can be saved and accessed through the USB port or Ethernet interface.

Mandrels of the same design as with NYFORS’ optical fiber recoaters could be mounted on the proof tester in the rotary high strength configuration. The fiber is wrapped around the two mandrels which support it using a special clamping mechanism. In this way greater loads can be applied on the fiber, enabling breaking strength tests under controlled circumstances.

Adjustable clamp positioning facilitates testing using the highest force levels along with testing of short fiber lengths. The compact and light weight design helps make the instrument easy to move around in a laboratory environment and to integrate in a production work bench where space is at reduced. The device is actually a compact and lightweight instrument suitable for testing the potency of optical fibers approximately 30 N. The device is developed to meet all types of applications in which a strength test needs to be performed.

The device is designed with all the user under consideration. The SZ stranding line is easily positioned in the guided linear clamps, and also the testing starts automatically using a “One Touch” go button. The built in microprocessor controls all of the important parameters such as pulling force, pulling speed and hold time. This enables for a completely controlled test each and every time.

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

Two recoat injector configurations can be purchased. The PTR307 uses an automated pump to inject the recoat material. The amount of material dispensed by the automatic injector is controlled manually via the top-mounted “Inject” button or programmed to the machine using the tablet controller. The PTR307B features a manual recoat injection system that needs the user to manually dispense the recoat material into the mold cavity; a replacement injector for that PTR307B recoater is available below. Please be aware uojthk the automated injector is only compatible with high-index recoat material, as the manual injector is compatible with both low- and- index recoat material; both are sold separately below. Please contact Tech Support for additional information.

he manual injector can be mounted to compatible fiber recoaters using the 4-40 screws on the recoater housing (see photo off to the right). Make use of a 3/32″ hex answer to secure the injector just before use. To connect the PTRRRM to the recoater mold, tighten the connector after the green plastic tubing, then loosen by a 1/4 consider allow for rotation.

The injector is equipped with a distribution valve and two-position selection lever for directing the flow of recoat material. A knurled dispensing screw having an internal plunger works as a syringe for that 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 inside the photo off to the right). Then, to inject the optical fiber proof-testing machine, point the lever horizontally (i.e., facing the knurled screw) and rotate the screw clockwise until nearby the end from the travel range is reached. Avoid bottoming out the dispenser because this may damage the inner plunger; also be careful when re-engaging the threads to prevent cross threading the dispensing screw. Several fill/inject steps may be needed until air is displaced inside the system. Use lens tissue as well as an acetone or alcohol cleaning solution to collect any excess recoat material that flows from the mold.
