By understanding the role of your ISP, you can better appreciate the complexity and technology that goes into delivering internet to your house.
How does fiber optic internet work and how is it delivered to my house?
Fiber optic internet works by using light to transmit data through thin glass or plastic fibers. These fibers are bundled together into cables, which are then laid underground or strung from telephone poles to connect homes and businesses to the internet. When you request data from the internet, such as a website or video, the request is sent through the fiber optic cable to a nearby server, which then retrieves the data and sends it back to your home through the same cable. This process happens rapidly, allowing you to access the internet quickly and efficiently.
The delivery of fiber optic internet to your house typically involves several steps. First, the ISP lays down the fiber optic cables in your neighborhood, either by digging trenches and burying the cables underground or by stringing them from telephone poles. The cables are then connected to a nearby fiber optic hub, which serves as a central connection point for multiple homes and businesses. From there, the fiber optic signal is transmitted to your home through a smaller cable, where it is received by a router and converted into a format that your devices can understand. This allows you to connect to the internet using a wired or wireless connection.
What is the difference between wired and wireless internet connections?
Wired and wireless internet connections are two different methods of accessing the internet from your home. A wired connection uses a physical cable, such as an Ethernet cable, to connect your device directly to the internet.
