Setting up the FRITZ!Box for use with a fiber optic connection

With an additional fiber optic modem, you can also use your FRITZ!Box on a fiber optic connection. Since the FRITZ!Box establishes and controls its own Internet connection over the fiber optic modem, all FRITZ!Box functions (such as Internet telephony, firewall) are also available without restriction in this operating mode.

Note:The terms "fiber optic connection" or "Fiber to the Home" (FTTH) are used for Internet connections where the fiber optic lines lead to a fiber optic modem in the home.

Important:Some of the settings described here are only displayed if the advanced view is enabled in the user interface. The configuration procedure and notes on functions given in this guide refer to the latest FRITZ!OS.

1 Connecting the fiber optic modem and the FRITZ!Box

  1. Connect the fiber optic modem to the fiber optic socket according to the instructions provided by your Internet service provider.
  2. Use a network cable to connect the LAN port on the fiber optic modem to the "LAN 1" port on the FRITZ!Box.
  3. Connect a computer to the FRITZ!Box over wireless LAN or use a network cable to connect it to an available LAN port on the FRITZ!Box.

2 Configuring the Internet connection

  1. Click "Internet" in the FRITZ!Box user interface.
  2. Click "Account Information" in the "Internet" menu.
  3. Check whether your Internet service provider is displayed in the drop-down list. With some regional settings, not all of the preconfigured Internet providers are displayed until you select "More Internet service providers".
    • If your Internet service provider is displayed in the drop-down list:
      1. Select your Internet service provider.
      2. If account information is required for Internet access, enter the account information you received from your Internet service provider in the "Account Information" section.
      3. Click on "Change connection settings".
      4. Enable the option "Via an external modem" in the "Internet Connection" section if it is displayed.

      2. Enable the option "External modem or router" in the "Connect via" or "Connection" section.
      3. Enable the option "Establish own connection to the Internet" in the "Operating Mode" section.
      4. If account information is required for Internet access, enter the account information you received from your Internet service provider in the "Account Information" section,
        • or, if account information is not required for Internet access:
          • Enable the option "No" in the "Account Information" section.
      5. If a particular VLAN ID is required for Internet access, click on "Change connection settings", enable the option "Use VLAN for Internet access" in the "VLAN Settings" section, and enter the VLAN ID you received from your Internet service provider in the "VLAN ID" field.
  4. Enter the relevant speeds of your Internet connection in the "Downstream" and "Upstream" fields.
