200um Large Core Optical Fiber, Step-Index Single Clad Fiber for Sensing & Laser Systems
Product Introduction
200μm large-core diameter step refractive index single-clad optical fiber is a special optical fiber specifically designed for high-power laser transmission and long-distancae sensing applications. Through its unique step refractive index waveguide structure and large core diameter design, it significantly enhances power processing capacity and coupling efficiency while ensuring excellent beam quality, thus becoming the core transmission medium for industrial lasers,medical equipment and high-end sensing systems.
Core advantages
Outstanding power handling and high coupling efficiency
Compared with the traditional single-mode fiber, the 200μm large core diameter significantly increases the light-conducting area, enabling the fiber to withstand and transmit higher optical power and easily handle kilowatt-level laser applications. Meanwhile, the larger receiving aperture reduces the alignment accuracy requirements, making the coupling with components such as lasers and detectors more convenient and faster, significantly enhancing the system integration efficiency and lowering the installation cost.
Excellent bending resistance and mechanical reliability
With an optimized step refractive index profile and a robust single-clad structure, this optical fiber maintains a large mode field diameter while still having excellent bending resistance and can operate stably in complex cabling environments. Its inherent high-strength characteristics also ensure long-term reliability and durability in harsh industrial environments.
Low-loss transmission and excellent signal-to-noise ratio
This optical fiber achieves low-attenuation transmission over a wide wavelength range and is particularly suitable for long-distance sensing and energy transmission applications. The low-loss characteristic means that the signal attenuation is small during transmission. For applications such as distributed acoustic sensing or long-distance gas detection, it can ensure that high-intensity and high signal-to-noise ratio signals can still be obtained at the remote end, greatly improving the perception accuracy and reliability of the system.
Wide application adaptability
From the energy transmission of industrial laser welding/ cutting equipment, to the distributed optical fiber sensing system for oil and gas pipeline safety monitoring, and to the laser delivery of medical laser treatment devices, this optical fiber can provide stable and efficient solutions. Its outstanding performance makes it an indispensable”highway of light“connecting high-power light sources with complex application terminals.
Summary
200μm large-core diameter step-refractive index single-clad fiber, with its high power capacity, high coupling efficiency, excellent stability and wide application adaptability, is becoming a key factor driving the development of high-end laser technology and precision sensing systems. Whether in the industrial field that pursues ultimate processing efficiency or in the scientific research and security fields that require precise detection, it is the foundation and guarantee for building the next-generation high-performance photonic system.
