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/telephone cable (Y cable)
Important:You can only extend the short ends of the DSL/telephone cable that lead to the DSL and landline. Signal interference may occur if the common DSL/telephone part of the cable is extended.
The following maximum lengths are possible:
- A maximum of 100 meters between the FRITZ!Box and analog landline.
- Up to 20 meters between the FRITZ!Box and DSL line; many DSL lines allow even more.
Note:If you are making your own DSL cable, we recommend using CAT 5 UTP network cables.
2 Telephone cable
The cable between a telephony device and an analog extension on the FRITZ!Box may normally be up to 100 meters long, but it depends on the telephony device used.
3 Network cable
The network cable between the FRITZ!Box and a computer or hub/switch may be up to 100 meters in length.
4 USB cable
The cable of USB devices connected to the USB port on the FRITZ!Box should not exceed 5 meters.
