A fiber-optic modem is a device that connects your home or office to the internet using fiber-optic cables. These cables are made of thin strands of glass or plastic that transmit data as light signals, allowing for faster and more reliable internet connections compared to traditional copper cables. This technology is especially beneficial for activities that require high-speed internet, such as streaming videos or online gaming. When you use a fiber-optic modem, it converts the light signals from the fiber-optic cables into electrical signals that your devices can understand. This means you can enjoy a seamless online experience with minimal lag. Many internet service providers offer fiber-optic plans, making it easier for users to access this advanced technology.
