Overview
The Sumitomo Electric Lightwave JR-7 Thermal Jacket Remover is a high-precision, portable tool engineered for the efficient removal of UV-cured fiber coatings. Designed for both field operations and production environments, this tool ensures clean coating removal without damaging the glass fiber, supporting a range of single fibers and 2–12 fiber ribbons.
Equipped with four adjustable temperature settings ranging from 80°C to 140°C, the JR-7 allows technicians to optimize stripping performance based on specific fiber coating requirements. Its robust, ergonomic construction features a durable metal lid and integrated LED illumination to enhance visibility in low-light working conditions. The device provides tactile feedback through vibration notification once the coating is thermally prepared for removal, streamlining the splicing preparation workflow.
Key Features
-
Adjustable Temperature Settings
Four distinct heat levels (80°C to 140°C) allow for precise optimization across various fiber types and coating thicknesses. -
Versatile Fiber Compatibility
Capable of stripping single fibers and 2–12 fiber ribbons with coating diameters between 200µm and 400µm. -
Tactile Vibration Feedback
Integrated vibration notification signals when the coating is sufficiently softened, ensuring efficient removal and reducing risk of fiber damage. -
Flexible Power Options
Powered via AC adapter, internal rechargeable Li-ion battery, or direct DC connection to compatible fusion splicers. -
Enhanced Visibility
Built-in LED illumination improves accuracy and safety during fiber positioning in dim environments. -
