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.
You can also use your FRITZ!Box on a fiber optic connection (Fiber to the Home, FTTH) with an additional fiber optic modem.
Since the FRITZ!Box establishes and controls its own internet connection over the fiber optic modem, all FRITZ!Box functions (such as firewall, parental controls) are also available without restriction in this operating mode.
1 Connecting FRITZ!Box to the fiber optic modem
Insert one end of a network cable into the 'WAN' 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
Enter the FRITZ!Box password given on the type label of the FRITZ!Box and click on 'Log In'.
Click on 'Internet' and then on 'Account Information'.
Select 'DSL or fiber optic modem' from the 'Internet connection via' drop-down list.
If your internet service provider is displayed in the drop-down list, select your provider and enter the account information you received from the internet service provider in the corresponding fields.
If your internet service provider is not displayed:
Select 'other internet service provider'.
Enter the account information you received from the internet service provider in the relevant fields. If account information is not required, enable the 'No' option.
Enter the speeds of your internet connection in the 'Downstream' and 'Upstream' fields.
If the internet service provider requires you to use a particular VLAN ID, click on 'Change Connection Settings', enable the 'Use VLAN for internet access' option, and enter the VLAN ID.
Click on 'Apply' to save the settings.
Now the FRITZ!Box checks whether the internet connection can be established. Configuration is complete as soon as the message 'The internet connection check was successful' is displayed.
Note:If the internet connection check fails, your internet access may not have been activated yet, or the account information is incorrect. In this case, contact the internet service provider.
