They are thin, flexible cables made of glass or plastic that transmit data using light signals. Fiber optic cables are capable of transmitting data at high speeds and over long distances, making them ideal for internet connections.An Optical Network Terminal (ONT) is a device that connects the fiber optic cable to your home or business. The ONT converts the light signals transmitted by the fiber optic cable into electrical signals that can be used by your devices. The ONT also provides a connection for your router, which allows you to connect multiple devices to the internet. A router is a device that connects to the ONT and provides wireless internet access to your devices. The router takes the electrical signals from the ONT and broadcasts them wirelessly, allowing your devices to connect to the internet. Some fiber optic internet providers offer a combined ONT and router device, while others require you to purchase y. Ethernet cables are used to connect your devices to the router. They provide a wired connection that is faster and more reliable than a wireless connection. Ethernet cables come in different lengths and categories, with Cat 5e and Cat 6 being the most common for home use.A Network Interface Card (NIC) is a device that allows your computer to connect to the internet. Most modern computers come with a built-in NIC, but older computers may require an external NIC for fiber optic internet connections.
