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

The FRITZ!Box is optimally prepared for use with Stiegeler. Simply connect the FRITZ!Box to the fiber optic connection and enter your personal account information in the FRITZ!Box user interface. If Stiegeler provided you with the FRITZ!Box, it will be configured automatically.

The complete FRITZ!Box range of functions for internet, telephony, and smart home is then available to all of the devices in your home network without restriction.

Requirements / Restrictions

  • A FRITZ!Box with the SFP module "FRITZ!SFP AON" is required for AON fiber optic connections.
  • A FRITZ!Box with the SFP module "FRITZ!SFP GPON" is required for GPON fiber optic connections.

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

1 Having your account information ready

  1. Have your personal account information for internet access and the login information for telephony that you received from Stiegeler ready.

    Note:You will find the account information in the letter that Stiegeler sent you before activating your connection. If you did not receive your account information, contact Stiegeler.

  2. If you have a GPON fiber optic connection, make note of the ONT installation ID on the type label of the ONT that you received from Stiegeler.

Modem ID on the FRITZ!Box's type label
