  • How many network cables and routers are needed for fiber optic internet access

    How many network cables and routers are needed for fiber optic internet access

    Fiber optic internet offers incredible speed and reliability. You'll typically need an Optical Network Terminal (ONT) provided by your installer, an Ethernet cable to connect the ONT to your router, and your own high-performance router. Unlike copper wires used in cable internet, fiber-optic cables consist of thin, glass fibers that transmit data as pulses of light, carrying information much faster with less interference. As a result, user devices can enjoy high-speed, latency-free Internet performance. What is Fiber Internet and Why Upgrade?The ONT converts the light signals from the fiber optic cable into electrical signals that can be used by standard network devices.
