  • Principle of Multimode Step Fiber

    Principle of Multimode Step Fiber

    Step-index multimode fibers operate on the principle of total reflection and allow traveling of light across the fiber/core axis in a zigzag pattern. The fiber core is often quite large — for some large-core fibers not much smaller than the whole fiber (see Figure 1). At the same time, the numerical. In optical fibers, a step-index fiber is a fiber where a uniform refractive index exists within the core and a sharply decreased refractive index exists in the core-cladding interface because of the lower refractive index in cladding. These fibers are still widely use for LAN and enterprise applications. Step ind x MMF are characterized by significant number of modes propagating through fiber. Multi-mode links can be used for data rates up to 800 Gbit/s.

  • Do I need a pigtail when installing a network cable

    Do I need a pigtail when installing a network cable

    A pigtail is used to provide fiber optics with a connector. This creates a stable and reliable connection between network. When you build or upgrade a fiber network, the same four words pop up everywhere— fiber optic (bare fiber), pigtail, patch cord, optical cable. They're related, but they are not interchangeable. Mixing them up drives costs higher, increases loss, and slows your rollout. It ensures a secure connection by combining wires with a wire connector, like a twist-on connector or a wire nut, and then linking them to the intended terminal or fixture. In fiber optics, pigtails are fusion-spliced to field fiber inside splice trays — the most common termination method in telecom and data center networks.
