The best
fibre network for

Switzerland’s best fibre network is getting bigger all the time. With annual investments of around 1.7 billion, we will have connected between 75 and 80% of all Swiss households and businesses by 2030. The fibre network is to be completed in all Swiss municipalities beyond 2030. At the same time, we will, over the coming years, start gradually taking our approximately 150-year-old copper access network out of service. We want everybody to be ready to use the opportunities of tomorrow.

“By replacing the approximately 150-year-old copper network with fibre, we will save around 100 GWh of electricity per year, equivalent to the annual consumption of a city of 20,000 inhabitants.”

Gerd Niehage, Head of IT, Network & Infrastructure, on the gradual retirement of the copper network.

So long, copper

After around 150 years, the copper era is gradually coming to an end. While copper has already been replaced by optical fibre in the exchanges and distributors in recent years, the plan now is to gradually replace the last few metres of copper cable in the regions. Besides improving the efficiency of the network, the copper phaseout will also make the network more sustainable. By the time of its complete retirement in the 2030s, we will be able to save the same amount of energy as the annual consumption of a city of 20,000 inhabitants.

The original installation of the copper cables was an arduous task. In 1962, for example, Quinten was connected to the telephone network by a copper cable weighing 15 tonnes. PHOTOPRESS ARCHIVE KEYSTONE

FAQs on the copper phaseout

Swisscom is planning a gradual phaseout of the copper network. All affected customers will be informed in advance. This page provides key details about the plans.

Residential customers – what do I need to know about the planned copper phaseout?

To make the switch, the fibre-optic network must have been rolled out to your location and you must have an installed fibre-optic socket in your home. If your home does not yet have a fibre-optic socket, Swisscom will arrange for it to be installed by a selected partner. Installation will be triggered as soon as you order a new product on the available fibre-optic network, request a switch, or Swisscom automatically transfers your existing products to the fibre-optic network.

You can check whether products are already available on your fibre-optic network on the Swisscom Checker.

This means that fibre is not yet available at your location. Information about the Swisscom fibre-optic network is usually available around 18 months before the rollout. As soon as the fibre-optic network is available in your area, Swisscom customers like yourself will be sent a letter with more information.

As soon as the fibre-optic network is available in your area, Swisscom customers like yourself will be sent a letter with more information. From this point on, you can switch your Swisscom products over to the fibre-optic network.

You can either apply to switch yourself in the Swisscom Customer Center or call into a Shop or call the hotline and have our employees take care of everything for you. If the switch will be triggered automatically by Swisscom with no further action is required by you for the time being.  

If your home does not yet have a fibre-optic socket, you or, in some cases, the property owners will be contacted by a Swisscom partner to arrange an installation appointment.

Swisscom will arrange authorisation for the structural change as well as the location of the fibre-optic socket with the property owners in advance. The installation partners will need access to your home to install the fibre-optic socket. Employees of the installation partner are required to identify themselves with a Swisscom badge and complete the work in your home within 1 working day.

Once the installation is complete, Swisscom will provide you with all the necessary equipment to switch your products over to the fibre-optic network.  

Switching your existing Swisscom products over from copper to fibre is generally free of charge. Both the installation of the fibre-optic socket and the necessary equipment for connecting to the fibre-optic network are provided by Swisscom free of charge.

In certain cases, property owners will be charged participation costs for the fibre-optic connection in the building (in-house connection) – for example, if it is a subsequent connection.

Additional costs may be charged for optional services beyond those mentioned. A transparent quotation will be submitted for such services in advance.  

No, existing products/subscriptions can usually be transferred to the fibre-optic network without adjustment. However, you will have the option of switching to a faster Internet subscription on fibre with a bandwidth of up to 10 Gbit/s.

The copper network will be phased out shortly after the fibre rollout. A sufficiently long transition period will therefore be available for the switchover. 

In exceptional cases, it might not be possible to connect a location to the fibre-optic network. In such cases, Swisscom will provide alternatives (a mobile or satellite connection for example).

In addition to an active fibre-optic socket in your home, you will also need a fibre-compatible router. Swisscom will provide this router, together with instructions on switching. 

If a fibre-compatible router is already in operation, you will be provided with a fibre-optic cable with connector. 

If you already have a previously installed fibre-optic socket, Swisscom will need the number shown on the socket.  

No, as soon as Swisscom announces the disconnection of the copper access network at your location, your products must be switched over to the fibre-optic network to ensure the continuation of your Swisscom services.

Even if the copper access network in your area is not yet to be disconnected, we recommend that you switch over to the fibre-optic network to enjoy its associated benefits.  

Yes, you will also need to switch in this case, as Swisscom fixed network telephony is based on Internet technology and therefore requires an Internet connection. When switching a fixed-line telephone to the fibre-optic network, there will once again be no costs for installation of the fibre-optic socket and required equipment.

Additional costs may be charged for optional services beyond those mentioned. A transparent quotation will be submitted for such services in advance.  

Telecommunications service providers – what do I need to know about the planned copper phaseout?

It will mean that any services currently provided on the copper network will have to be switched over to fibre.

The continuing rollout of the fibre-optic network will allow Swisscom to gradually retire the old copper network. From a financial and sustainability perspective, it makes no sense to operate two networks in parallel for the same purpose. Copper technologies are also more susceptible to interference and will soon stop being maintained by manufacturers.  

Swisscom will phase out the copper network successively, one access network at a time. This will take several years and continue into the 2030s.

Swisscom will provide more detail about the affected access networks and addresses within the first half of 2024. We are planning to update our ordering systems accordingly and provide information for each line.

Active connections will be terminated in tranches, usually subject to a 24-month period of notice. Shorter notice periods may apply in exceptional cases. For example, if Swisscom is forced to dismantle local exchanges due to expiring leases that are not renewed.

In the initial phase, Swisscom will only disconnect the copper access network at locations where customers typically already have optical fibre access. There may be individual cases in all areas where buildings are not accessible because the owner has refused a fibre connection.
