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

You want to set up the FRITZ!Box on a fiber optic connection? ✔ It's easy with this guide.

To establish an internet connection via your fiber optic connection (Fiber to the Home, FTTH), connect the FRITZ!Box to the fiber optic connection and enter your account information in the FRITZ!Box user interface.

Requirements / Restrictions

  • The fiber optic connection must comply with the standard ITU-T G.652 (AON). Use with a passive fiber optic network (ITU-T G.984, GPON) is not supported.

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

1 Connecting the FRITZ!Box to your fiber optic connection

  1. Connect the fiber optic cable to the "Fiber" socket on the FRITZ!Box and the fiber optic socket. Do not bend the fiber optic cable and do not hold the ends of the cable in front of your eyes.

    Note:The FRITZ!Box has an SC/PC connector (wide connector, flat endface). Depending on the fiber optic socket, you may need to use a fiber optic cable with an adapter. The fiber optic cable is not included with your FRITZ!Box, it is supplied by your internet service provider.

2 Configuring the internet connection in the FRITZ!Box

  1. Open the FRITZ!Box user interface.

  3. If the menu "Account Information" is not displayed automatically, click "Account Information" in the "Internet" menu.
  4. Select your internet service provider in the drop-down list. If your internet service provider is not displayed, select "other internet service provider" from the drop-down list.
  5. If account information is required, enter the account information you received from your internet service provider in the corresponding fields.
    • If account information is not required, enable the option "No" in the "Account Information" section.
  6. If you selected "Other internet service provider" and your internet service provider requires you to use a particular VLAN ID:
    1. Click "Change connection settings".
    2. Enable the option "Use VLAN for internet access".
    3. Enter the VLAN ID and PBit in the corresponding fields.
