This FTTH Cable Production Line is made for operator skill independent utilization in production and laboratory settings. Two basic model configurations permit the user to choose between a setup for standard linear proof testing and 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 coating is not damaged within the testing process while at the same time eliminating the necessity for an external air supply. Degrees of pulling force, pulling speed and hold time are programmable and conveniently accessible to the operator from the built in LCD touch-screen control. Data from tests could be saved and accessed via the USB port or Ethernet interface.
Mandrels the exact same design as in NYFORS’ optical fiber recoaters may be easily 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. This way higher loads can be applied onto 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 definitely makes the instrument easy to maneuver in a laboratory environment and also to integrate in a production work bench where space reaches reasonably limited. The equipment is really a compact and light-weight instrument ideal for testing the potency of optical fibers up to 30 N. The device is designed to meet all types of applications where a strength test needs to be performed.
The device was created using the user in your mind. The fiber is readily put into the guided linear clamps, and also the testing starts automatically using a “One Touch” go button. The built in microprocessor controls all the important parameters like pulling force, pulling speed and hold time. This allows for a completely controlled test each time.
The Optical Fiber Ribbon Machine can be linked to another PC, which enables usage of all programmable parameters and settings. The machine is adapted to stand-alone use or even to the integration into different subsystems. The equipment posseses an extensive capacity for logging and saving information like pulling force, pulling speed and fiber diameter and other parameters.
Two recoat injector configurations are available. The PTR307 uses an automated pump to inject the recoat material. The amount of material dispensed from the automatic injector is controlled yourself through the top-mounted “Inject” button or programmed to the machine using the tablet controller. The PTR307B features a manual recoat injection system that will require the fseejm to manually dispense the recoat material to the mold cavity; a replacement injector for your PTR307B recoater is accessible below. Please be aware that this automatic injector is simply suitable for high-index recoat material, as the manual injector is compatible with both low- and high- index recoat material; both are sold separately below. Please contact Tech Support for additional information.
he manual injector may be mounted to compatible Secondary Coating Line via the 4-40 screws on the recoater housing (see photo to the correct). Make use of a 3/32″ hex key to secure the injector just before use. To get in touch the PTRRRM to the recoater mold, tighten the connector at the end of the green plastic tubing, then loosen with a 1/4 turn to enable rotation.
The injector is equipped with a distribution valve as well as 2-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 correct). Then, to inject the recoat material to the mold, point the lever horizontally (i.e., facing the knurled screw) and rotate the screw clockwise until close to the end from the travel range is reached. Avoid bottoming the dispenser because this may damage the inner plunger; also be mindful 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 as well as an acetone or alcohol cleaning answer to collect any excess recoat material that flows from the mold.
