  • Fiber core of long-distance communication optical cable

    Fiber core of long-distance communication optical cable

    The fiber optic cable core is the physical glass medium that transports optical signals from an attached light source to a receiving device. Conventional optical fiber has a core that goes through the center for transmitting light. Professionals in telecommunications, data centers, and network infrastructure must understand the core functions and why they are fundamental to their fiber optic. An optical fiber, or optical fibre, is a flexible glass or plastic fiber that can transmit light from one end to the other.
