  • What is the working principle of a cable terminal box

    What is the working principle of a cable terminal box

    The working principle of the terminal box is relatively simple. When a wire is connected to a terminal, a conductive path is formed through the metal part of the terminal, and current can flow from one wire to another wire through the terminal. The design of terminals allows for quick connection. What is a terminal block? A terminal block (also called as connection terminal or terminal connector) is a modular block with an insulated frame that secures two or more wires together. It consists of a clamping component and a conducting strip. Terminal boxes keep your electrical connections safe and organized, helping prevent hazards and making sure everything runs efficiently.

  • Fiber Optic Thermal Fusion Panel Principle

    Fiber Optic Thermal Fusion Panel Principle

    FBT machines operate on the principle of controlled fiber fusion and tapering: Fusion Stage: Two or more bare fibers are aligned in parallel and fused under precise hydrogen/oxygen flame heating (typically at 1,400–1,600°C). This effect can lead to the rupture of the fibre or to the fibre fuse. Fused Bionical Taper (FBT) technology remains a cornerstone in passive optical network (PON) component manufacturing, particularly for fiber optic couplers, splitters, and WDM devices. At the heart of this process lies the FBT machine—a precision instrument combining thermal engineering, mechanical.
