What is FTTH?
The FTTH network (Fiber To The Home), or " Fiber to the
subscriber " in French, is a network which provides an optical fiber link
from the operator or the provider of Internet access to the interior itself. of
the subscriber's accommodation.
FTTH is one of the most efficient technologies for fixed
internet access :
It
promotes the performance and reliability of the passive infrastructure,
It offers
the fastest besides furthermost symmetrical connection speeds ,
It allows the development of new internet , multimedia and connected services uses thanks to speeds much higher than those of ADSL.
Fiber optics: your data at the speed of light
Glass or plastic thread thinner than a hair, the fiber
carries data by means of a light signal: this data travels at the speed of
light, with almost no limitation of flow or alteration by distance .
According to the European Commission, Cyber space entree is
considered to be Very High Hurry (THD) as soon as the speed is greater than 30
megabits per second ( Europe 2020 Approach ). The stretch throughput refers to
the amount of material that a web can assignment in a given time. It is
articulated in "bit", a unit of measurement of the quantity of data
likely to circulate in a network (kilobits, megabits or gigabits according to
the level of the flow). The higher the speed, the faster the speed of
transmission and reception of data (documents, videos, music, etc.).
What is the lifespan of an FTTH network?
Deploying an FTTH network is a long-standing speculation.
Indeed, if the life expectancy of an secretive ophthalmic cable is at least 25
years, the useful life of this technology will probably be longer. Thus, this
network is gradually replacing the local copper loop (telephone network), the
lifespan of which will have exceeded 50 years in most of the territory. Thus,
we speak of Mutualized Optical Local Loop (BLOM).
In addition, the capillarity of optical families is a key
issue for the 5G , facilitating the connections of radio
antennas, but also sensors and other community facilities within the smart
territories.
Deployment of the FTTH fiber network in France
In 2013, the French State launched the France THD Plan ,
which aims to cover the entire territory in THD by 2022. It represents a public
and private investment of a total of 20 billion euros. The government's two
watchwords are:
Cohesion :
the State wants to agreement every person access to good broadband (> 8Mbits
/ s) or very high speed and generalize quality mobile coverage (4G) by 2020,
Ambition : the State wants to provide all the territories of the Republic with cutting-edge digital infrastructures by offering THD access (> 30Mbits / s) by 2022.
In addition to the economic and social stake of the new
digital economy, the objective of this plan is to open up areas far from large
cities.
To generalize everyone's access to uses linked to THD, the France THD Plan plans to generalize the deployment of FTTH networks , gradually replacing copper in the telephone grid with optical fiber. All French premises (housing and professional launches) are targeted.
As of March 31, 2019, 14.5 million premises can be connected
to the FttH on approximately 37 million premises.
For businesses and public services
The France THD Plan makes areas of economic activity and
public services (schools, colleges, high schools, hospitals, nursing homes,
etc.) "priority sites" for the deployment of optical fiber.
For all the inhabitants
In some areas, the directions of the ARCEP entail that all
new buildings (excluding houses) is equipped with a fiber network at the foot
of the building.
A European issue
In 2025, in accordance with the objectives of the European Commission (Gigabit Society), all European households, rural or urban, will have access to a connection of at least 100 Mbit / s "upgradable" to reach 1 Gbit / s .
Although the European Commission 's Digital Agenda is neutral from a technological point of view, France has chosen FTTH, a solution it considers the most sustainable in the long term, due to its scalability. In 2022, more than 80% of homes should be eligible for FTTH.
A private and public commitment
As part of the France THD Plan, private operators undertake
to deploy FTTH networks with their own funds in areas of high population
concentration for which deployment is economically viable.
