Maximum cable lengths
The FRITZ!Box comes with various cables to connect it to your line, a computer, or hub, for example. If a cable is too short, you can extend or replace it. Since you can only extend cables to a certain limit, below you will find information on the maximum possible length for each type of cable.
1 DSL cable
The entire section of cable between the "telephone jack -- DSL splitter (not always present) -- FRITZ!Box" may be up to 20 meters long, often even longer. It depends on the distance between your DSL provider's exchange and your DSL line.
Note:If you are making your own DSL cable, we recommend using CAT 5 UTP network cables.
2 Telephone cable
Normally, the cable between a telephony device and an analog extension on the FRITZ!Box may be up to 100 meters long, but this depends on the telephony device used.
3 Network cable
The network cable between the FRITZ!Box and a connected device may be up to 100 meters long.
Note:Any standard STP-type (Shielded Twisted Pair, 1:1) CAT-5e Ethernet cable can be used to connect a network device to the FRITZ!Box.
4 USB cable
The cable of USB devices connected to the USB port on the FRITZ!Box should be a maximum of 5 meters long.
