  • Working principle of pigtail splicing reel

    Working principle of pigtail splicing reel

    The bare end of the pigtail is spliced to the main cable, creating a permanent, low-loss connection. This splicing process helps integrate fibers into panels, switches, and transmission equipment without excessive bending or physical strain. Get the wrong connector type, the wrong polish, or skip proper fusion splicing technique—and you're looking at elevated signal loss, increased back reflection, and a. A fiber pigtail is a short length of optical fiber that comes with a high-quality, factory-polished connector already installed on one end, leaving a length of exposed glass on the other. This post contains some basic knowledge of fiber optic pigtail, including pigtail connector types, fiber pigtail classifications, and fiber pigtail splicing methods.

  • Working principle of high-temperature fiber optic sensor

    Working principle of high-temperature fiber optic sensor

    Raman scattering-based fiber optic temperature sensors rely on the principle of Raman scattering, where light interacts with molecules in the fiber, causing a shift in the frequency of the scattered light. This shift is directly related to the temperature of the fiber. Fiber-optic high-temperature sensors are gradually replacing traditional electronic sensors due to their small size, resistance to electromagnetic interference, remote detection, multiplexing, and distributed measurement advantages. This paper reviews the sensing principle, structural design, and. High-temperature measurements above 1000 °C are critical in harsh environments such as aerospace, metallurgy, fossil fuel, and power production.
