  • There is light in the optical cable

    There is light in the optical cable

    Optical cables transmit data as light pulses through strands of fiber. Unlike traditional copper cables, which rely on electrical signals, optical fibers use light, making them faster and less susceptible to interference. However, this technology has its complexities and challenges. The first step. A faulty optical cable can manifest in various ways, depending on the type of device it's connected to and the nature of the problem.
