Setting up the FRITZ!Box for use with a fiber optic connection
You want to use the FRITZ!Box with a fiber optic modem? ✔ It's easy with this guide.
Not only can you use your FRITZ!Box with an integrated DSL modem on a DSL line, you can also use it with an additional fiber optic modem on a fiber optic connection (Fiber to the Home, FTTH).
Since the FRITZ!Box establishes and controls its own internet connection over the fiber optic modem, all FRITZ!Box functions (such as firewall, telephony) are also available without restriction in this operating mode.
Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.
1 Connecting FRITZ!Box with the fiber optic modem
- Insert one end of a network cable into the "LAN 1" port on the FRITZ!Box. Use the network cable supplied with the FRITZ!Box, for example.
- Insert the other end of the network cable into the LAN port on the fiber optic modem (ONT, Optical Network Termination).
2 Configuring the internet connection in the FRITZ!Box
Configuring the Telekom internet connection
These steps are only necessary if you are using the FRITZ!Box on a fiber optic line from Deutsche Telekom:
- Open the FRITZ!Box user interface.
- Enter the FRITZ!Box password on the bottom of the device and click "Log In".
