Fiber vs ADSL in France: 2026 Comparison
This guide compares fiber optic (FTTH), VDSL and ADSL in France: how each works, how to check what is available at your address, and what the closure of the copper network means for you.
Understanding the technologies
Three main internet connection technologies are available in France: fiber optic (FTTH), VDSL, and ADSL. They differ in speed and availability.
Fiber optic (FTTH)
Fiber optic uses glass or plastic strands to transmit data as light signals. The cable runs directly into your home (FTTH = Fiber To The Home).
- Light transmission
- Speed set by the plan you choose
- Professional installation
VDSL
VDSL (Very-high-bit-rate Digital Subscriber Line) is an upgraded version of ADSL that achieves higher speeds over short distances.
- Uses telephone lines
- Speed depends on the length and quality of the copper line
ADSL
The original technology that launched broadband in France. Uses standard telephone lines.
- Copper telephone lines
- Speed depends on the length and quality of the copper line
Speed: what depends on what
Speed is a main difference between the three technologies. VDSL and ADSL speeds depend on the copper line; fiber speed depends on the plan you choose. This guide gives no figures: check the speed announced for your address by your operator.
| Technology | What the speed depends on |
|---|---|
| Fiber optic | The plan you choose |
| VDSL | The length and quality of the copper line |
| ADSL | The length and quality of the copper line |
VDSL: the middle ground
VDSL is easy to overlook. It makes sense in these cases:
Choose VDSL if:
- Your location is not eligible for fiber but is close to a telephone exchange
- You need more speed than ADSL provides but fiber is not available
VDSL performance depends on the copper line
- The longer the copper line to the exchange, the lower the speed
- Ask your operator for the speed announced at your address
Coverage and rollout
Fiber coverage varies by region and by address. ARCEP, the French telecommunications regulator, publishes the tool "Ma connexion internet", and you can also ask your operator.

Copper network shutdown
Important context
France is gradually closing the copper telephone network that powers ADSL and VDSL.
What this means
According to ARCEP, Orange, as owner of the copper network, pilots the closure plan, whose second phase runs from 2026 to the end of 2030. The closure happens in two steps for each municipality: a commercial closure, after which new subscriptions end while existing connections are maintained, and a technical closure, which ends the remaining copper access (source: ARCEP, La fermeture du réseau cuivre).
What you should do: If fiber is available at your address, ask your operator what a switch involves. Check on ARCEP's tool whether the copper closure has already started at your address.
Pros and cons
Fiber optic
Advantages
- Higher speeds than VDSL and ADSL
- Does not rely on the copper telephone network
Disadvantages
- Not available at every address
- Requires an installation by the operator or its provider
VDSL
Advantages
- Better speeds than ADSL when close to exchange
- Uses existing telephone lines
Disadvantages
- Performance degrades rapidly with distance
- Not available at every address
ADSL
Advantages
- Works with existing telephone line
Disadvantages
- Speed depends on the copper line
- Speed depends heavily on distance from exchange
- Depends on the copper network, which is being closed progressively
How to choose
Choose fiber if:
- Fiber is available at your address (check on the ARCEP map)
- You work from home and use video conferencing regularly
- Multiple people in your household use the internet simultaneously
- You stream content in HD or 4K
- You download or upload large files regularly
Consider VDSL if:
- Fiber is not available but you can get close to the exchange
- You need more speed than ADSL provides
- You are waiting for fiber rollout in your area
Stick with ADSL if:
- You are in an area without fiber or VDSL access
- Your internet use is limited to web browsing and email
Our advice: If fiber is available at your address, compare your operator's fiber offer with your current plan before deciding. The copper network is being closed progressively.
Frequently asked questions
Can I keep my mobile number when switching operators?▼
Yes, through number portability. According to Service-Public.fr (page consulted on October 6, 2026), you first get your RIO, a number of 12 digits or letters, by calling 3179 (a free call and service from a mobile phone, open every day, around the clock), then you give it to your new operator when you sign.
How do I find out which technologies are available at my address?▼
ARCEP's tool "Ma connexion internet" (maconnexioninternet.arcep.fr) is a cartographic search engine for fixed internet. For an address, it shows the operators and technologies available, including the status of the copper network. Your operator can also tell you what is available.
Is fiber available in rural areas?▼
Fiber coverage varies by region, so it can differ from one address to the next. Check your address on ARCEP's "Ma connexion internet" tool at maconnexioninternet.arcep.fr. Where fiber is not available, your operator can tell you which technologies are available at your address.
