    • How does Fiber Optic Technology work? When you access the Internet, a fiber optic cable carries the laser-generated pulses of light to transmit the data signal to your home. Once the signal has arrived, an Optical Network Terminal (ONT) converts it to an electrical signal that is understood by your computer.

    Your ONT takes all converted incoming information and delivers it to your router via an Ethernet cable. After the signal has passed through your firewall, the Ethernet cable carries the signal to the Network Interface Card plugged into your computer.

    When you send an email or other data over the Internet, the electrical signal from your computer is converted back to light signals by the ONT and transmitted to the recipient over the fiber optic cable. This allows for the remarkably fast transfer of information.
