Wifirst fibre-to-the-premises: a dedicated offer for businesses
Professional fiber throughout France, at the best price.
Why install Wifirst fiber optics?
Optical fiber enables data to be transmitted at the speed of light and provides very high bandwidth. At a time when the quality of the Internet connection is a key factor in both customer satisfaction and employee productivity, fiber optics pro is the ideal solution for companies looking to improve their performance. In short, fiber optics represent a significant advance over ADSL, offering far superior performance and meeting the growing demands of modern connectivity.
A multi-operator network for best-price fiber to the home
The Wifirst network boasts unrivalled capillarity and availability, thanks to collection agreements with both major operators and alternative players. This "mix" of operators enables Wifirst to select the most efficient collection sub-networks according to the geographical location of the site to be connected, the quality and resilience of the sub-network near the site, and of course, economic conditions.






A fiber optic pro, yes, but which one?
Dedicated pro fiber (FTTO)
FTTO fiber is a fiber used exclusively by your company, with genuine service commitments:guaranteed throughput, symmetrical throughput ( upload = download) andguaranteed 4-hourrecovery time in the event of failure. It is therefore designed to offer very high availability, as connectivity is critical in a business environment.
Fiber-to-the-home (FTTH PRO)
Mutualized pro fiber is a consumer offer that has been repackaged for businesses. It is known as FTTH Pro . Unlike dedicated fiber-to-the-home, this solution is a shared fiber offering for several establishments. Even so, it is capable of delivering high speeds(up to 1 Gbps, depending on operator and eligibility). However, this figure represents the maximum achievable throughput (referred to as "peak throughput").


Sizing your company's fiber optics pro
Sizing is essential. An underestimated bandwidth will generate slowdowns and frustrations. An overestimated throughput will result in unnecessary extra costs. We provide you with methods to help you order your FTTO fiber capacity as accurately as possible.

Why switch to fiber-to-the-premises?
Switching to professional fiber optics offers many advantages for businesses and establishments that welcome the public.
- High speed and bandwidth: Fiber optics offer much higher connection speeds than traditional connections, enabling faster data transfer. This is essential for businesses that need to download and share large files, manage data-intensive applications and ensure a smooth user experience.
- Reliability: Fiber optic connections are renowned for their reliability. They are less prone to disruption from electromagnetic interference, weather and hardware failure. This ensures stable, constant connectivity, which is essential for mission-critical business operations.
- Reduced latency: Fiber optics offer significantly lower latency than traditional technologies, which is essential for real-time applications such as videoconferencing, online financial transactions and online gaming.
- Enhanced security: Fiber optics are difficult to hack, as they do not radiate electromagnetic signals that hackers could intercept. This enhances the security of sensitive corporate data.
- Scalability: Fiber optic networks are easily scalable to meet your company's growth needs. You can increase bandwidth without having to replace existing infrastructure.
- Support for advanced applications: Fiber optics are needed to support advanced applications such as virtual reality, artificial intelligence, high-quality VoIP telephony and cloud computing, which are increasingly common in business environments.
In short, switching to professional fiber optics improves productivity, security, flexibility and competitiveness, enabling businesses to take full advantage of advanced digital technologies and adapt to changing connectivity needs.
Why is FTTO fiber more expensive than FTTH fiber?
The difference in cost between FTTH and FTTO fiber is linked to the level of service you receive. The FTTO offer guarantees throughput, which means you can cope with peak loads in hotels and student residences, for example. In the event of a technical problem, we are also committed to restoring your installation within a few hours. These two features make FTTO fiber an indispensable ally for businesses with high connectivity needs.
What if my site isn't eligible for fiber optics?
If you don't need too much bandwidth, Wifirst can aggregate several ADSL lines to provide an acceptable bandwidth. This is limited to certain cases, and does not take full advantage of the quality standards of the infrastructure deployed by Wifirst.
A 4G/5G or satellite connection may also be considered. These options may represent relevant alternatives for certain customers.
What are the advantages of symmetrical bandwidth?
Traditional Internet access offers generally feature a much higher download speed than upload. However, for certain uses, a high upload speed is necessary. This is particularly the case for videoconferencing, IP telephony, cloud computing and any other data-sending application.
Does the quality of a WiFi network depend on fiber optics?
A WiFi infrastructure can be optimized to maximize performance, but will always depend on the line speed. As a result, a limited data rate will always represent the biggest obstacle to a quality WiFi service in a configuration with demanding connectivity needs. Fiber optics, and more specifically dedicated fiber, are therefore highly recommended for powering a wireless infrastructure.
