  • How do fiber optic panels work

    How do fiber optic panels work

    Fiber optic patch panels are enclosures that act as a distribution hub for fiber cable. A bulk (multi-strand) fiber cable enters the patch panel and then each fiber strand is separated into individual strands or pairs of strands. These 'light off' and 'light on' states are created by sending photons bouncing down the fibre optic core through a process known. Fiber optics is the technology associated with the transmission of information as light pulses along a glass or plastic strand or fiber.
