Please check the availability of fiber at your address. To use fiber internet you need a fiber optic outlet (also called OTO outlet). This fiber optic outlet is an optical telecommunication outlet (= OTO for Optical Termination Outlet). In order to connect your home to fiber optic internet, we need your fiber optic number, also called OTO-ID.

- The number is printed directly on the glass fiber socket (OTO socket)
- The number usually starts with A or B (in exceptional cases with O or WP) followed by 10 digits in the following format: A.XXX.XXX.XXX.X.
- If necessary, your administration or your previous tenant can give you information about this.

If there is no fiber optic socket, a technician must perform the installation. We are happy to support you in this. Here you can find more details about the process.

If you already have a fiber optic socket at home and you provide the fiber number (OTO ID) when ordering, the activation will take about 15 days. If you do not have a fiber optic socket, the activation will take about 3 weeks, because a technician has to install this socket at your home. In exceptional cases it can take up to 6 weeks.

No, you have to cancel the contract with your previous Internet provider yourself. Please note the notice periods here. If you are already surfing on fiber optic technology, we also strongly recommend you to cancel before ordering fiber internet products to avoid a delay in the activation.
