Polyimide Fiber F_AS 400440 IR PI
Polyimide fiber, also called polyimide-coated fiber, uses a polyimide coating. This polymer offers good high- and low-temperature resistance, mechanical strength, and overall performance. It withstands up to 380°C, with a long-term range of -200 to 300°C. Some varieties have no distinct melting point. It provides high insulation, dielectric constant 4.0 at the source-stated 103 hertz, and dielectric loss of only 0.004-0.007. Production generally includes core and cladding preparation and polyimide coating. The lengthy coating process reduces production efficiency, and its high modulus prevents removal with stripping pliers. Overall, heat and corrosion resistance enable high-performance fiber use in many special environments.

Fiber Processing Tools C108 Optical Fibers Jcoptix
Compatible Fiber Types: Single-Core Silica Fiber Compatible Fiber Specifications: Ø0.25 mm/Ø0.9 mm/Pigtail Clamp Type: Multifunction Fixture
JCOPTIX offers the full COMWAY range of high-quality fiber-processing tools, combining high precision, efficiency, long life, and versatility. Precise blade-gap calibration for thermal stripping and stripping tools avoids core damage and removes coatings evenly without residue. Convenient operation and maintenance support fiber splicing in communication engineering, data centers, FTTH, emergency field repair, research, and teaching, making them standard tools for professional splicing. Fiber cleavers. Models: CC-03, C108, C109, C109M. High-precision cleaving. Durable, long-lived construction. Easy operation and maintenance. JCOPTIX supplies original COMWAY cleavers with precision mechanics and hard-alloy blades for stable cleave angles. Blade life reaches up to 48000 cleaves, combining efficiency, precision, and durability. Place fibers in the correct groove strictly according to instructions. If fibers do not cleave or edges are rounded, adjust the blade position with the screw and cleave again. If quality deteriorates noticeably, generally after 1000-1500 fibers, loosen the blade-clamping screw and adjust the blade position according to instructions. Thermal fiber strippers. Models: CS-06, CS-09. Thermal stripping without fiber damage. Four temperature settings and dual modes. Portable, long battery life. Easy operation and maintenance. Original COMWAY strippers use constant-temperature thermal stripping instead of conventional cold stripping to avoid core scratches and coating residue. Four temperatures, dual modes, a high-capacity lithium-ion battery, and Type-C fast charging suit bundled fibers, ribbon cables, pigtails, bare fibers, invisible fibers, and other fiber coatings. Replace both blades together according to instructions. Fiber stripping pliers. Model: CS-02-B. Three-hole design. Safety lock. Easy, quick operation. Original COMWAY pliers include 3 standard stripping openings for layered removal of 2.0-3.0 mm outer jackets, 900 μm buffers, and 250 μm coatings in one operation. Micrometer-calibrated hard-alloy blades prevent core scratches and breaks; ergonomic nonslip handles combine efficiency and durability. Users may adjust aperture size as needed, but manual adjustment cannot be restored to factory settings with one action. Open the safety lock before use.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
