Setting up FRITZ!Box for use with an Adamo line

The FRITZ!Box is optimally prepared for use with Adamo. Simply connect the FRITZ!Box to the fiber optic connection and enter your personal account information in the FRITZ!Box user interface.
The complete FRITZ!Box range of functions for internet, multimedia, and smart home is then available to all of the devices in your home network without restriction.
Important:Currently, the FRITZ!Box can only be used directly on fiber optic lines from Adamo with internet connections without telephony.
Requirements / Restrictions
- FRITZ!Box with SFP module "FRITZ!SFP GPON"
Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.
1 Determining the PON serial number
- Take note of the PON serial number (for example "GPON SN: [...]") on the type label on the fiber optic modem (ONT) or the router with an integrated fiber optic modem that you received from Adamo.
2 Inserting the SFP module into the FRITZ!Box
The FRITZ!Box is available in several different product variants, each of which is delivered with different components. If no SFP plug-in module was inserted in your FRITZ!Box, perform the following steps:
3 Connecting the FRITZ!Box to your fiber optic connection
- Remove the dust protection caps from the fiber optic cable, the SFP module in the FRITZ!Box, and from the fiber optic socket.
- Connect the fiber optic cable to the SFP module in the FRITZ!Box and to 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:You can find information on selecting a suitable fiber optic cable in our guide Which fiber optic cable do I need?
