All about fiber optics

The future of very high speed Internet is through fiber, a true locomotive of digital. Focus on the ten most frequently asked questions about this technology.
What is optical fiber?
An optical fiber is a particularly fine glass or plastic wire , capable of conducting light and used to transmit data. The signal, contained in a cylindrical core surrounded by a protective sheath, is transported by laser light. This light can easily be transported over hundreds, even thousands of kilometers. Beyond that, the fiber has the desired ability to allow communications at particularly high speeds .

What is the difference between fiber and cable?
The optical fiber is employed within a sheath and drawn:

in the streets: so-called “horizontal” deployment,
then in buildings: deployment known as "vertical",
Finally, even in the dwellings: we speak of "final connection".
This is an FTTH connection .

But fiber should not be confused with cable, known as “coaxial cable” - the famous “antenna cable”, through which Numericable-SFR offers its subscribers access to very high speed. Numericable-SFR already has a coaxial cable network which gives it a definite advantage over its competitors. In fact, the coaxial cable suffers little loss over short distances and remains an excellent support for supplementing the fiber.

Numericable-SFR fiber has therefore opted for a connection of its subscribers by FTTB technology and not FTTH: with this technology, from the foot of the building to the subscriber, Numericable-SFR has chosen to replace the coaxial cable to fiber. The purists will therefore reject the name "fiber" for Numericable-SFR, it being considered that the cable operator uses coaxial cable for the terminal part of the connection of its customers.
