Optical Fiber Coloring Machine – On What Point Of View Should You Really Make Your Mind Up..

This automatic optical fiber tensile testing system is designed for operator skill independent use in production and laboratory options. Two basic model configurations enable 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 designed for production proof testing with forces up to 22 N. Motorized clamps with carefully designed rubber inserts ensure that the FTTH cable production line is not really damaged within the testing process while concurrently eliminating the requirement for another air supply. Levels of pulling force, pulling speed and hold time are programmable and conveniently accessible to the operator from the built-in LCD touchscreen display control. Data from tests can be saved and accessed via the USB port or Ethernet interface.

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

Adjustable clamp positioning facilitates testing using the highest force levels as well as testing of short fiber lengths. The compact and light weight design definitely makes 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 perfect for testing the potency of optical fibers as much as 30 N. The equipment is developed to meet all kinds of applications where a strength test must be performed.

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

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

Two recoat injector configurations can be found. The PTR307 uses an automated pump to inject the recoat material. The quantity of material dispensed from the automatic injector is controlled yourself using the top-mounted “Inject” button or programmed to the machine making use of the tablet controller. The PTR307B includes a manual recoat injection system that will require the user to manually dispense the recoat material in to the mold cavity; a replacement injector for that PTR307B recoater is available below. Please note uojthk the automatic injector is simply suitable for high-index recoat material, whilst the manual injector works with both low- and high- index recoat material; both of them are sold separately below. Please contact Tech Support for additional information.

he manual injector could be mounted to compatible fiber recoaters using the 4-40 screws on the recoater housing (see photo off to the right). Use 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 conclusion of the green plastic tubing, then loosen with a 1/4 turn to enable 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 with an internal plunger behaves 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 in the photo 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 of the travel range is reached. Avoid bottoming the dispenser since this may damage the inner plunger; also take care when re-engaging the threads to avoid cross threading the dispensing screw. Several fill/inject steps may be needed until air is displaced within the system. Use lens tissue as well as an acetone or alcohol cleaning means to fix collect any excess recoat material that flows through the mold.
