Everything you need to know about FTTH

The FTTH Council Europe aims at advancing ubiquitous full fibre-based connectivity to the whole of Europe, with the vision that fibre connectivity will transform the way people live, do business and interact, connecting everyone, everything, everywhere. In fact, fibre connectivity can play a crucial role in contributing to a better, faster, and greener Europe.


What is FTTH?

Fibre to the Home (FTTH), sometimes known as Fibre to the Premises (FTTP), is a broadband internet connection technology that uses optical fibre to deliver high-speed broadband internet directly to individual buildings such as households, apartment complexes, and businesses. Unlike traditional twisted pair or coaxial cable networks, fibre optic cables made of thin strands of glass or plastic fibres can transmit data over long distances using light signals that are less prone to interference and signal loss as their copper counterparts. The characteristics guarantee much faster and more efficient data transmission compared to traditional broadband networks and make FTTH an ideal choice for providing internet access to residential and commercial customers in urban, suburban, and rural areas.

How does FTTH work?

The architecture of an FTTH network typically consists of a central office or hub, which hosts the equipment that connects the network to the internet. From there, the signal is sent over optical fibre cables to a distribution point, where it is then distributed to individual customers through a network of fibre optic cables.

The core components of an FTTH network include:

  • Optical fibre cable
  • Optical network terminals (ONTs)
  • Optical line termination (OLT) equipment
  • Passive optical splitters
  • Distribution frames

FTTH works by running optical fibre strands all the way to the internet service provider’s network to the customer’s house. This fibre optic cable is then connected to a device called an optical network terminal (ONT), which converts the incoming light signals into electrical signals.

From there, the electrical signals are distributed throughout the home using Ethernet or other wired or wireless technologies.

What is the installation process like?

The installation process for FTTH involves a few key steps. First, the layout for the access network is designed, planned, and operated. Afterward, or more optimally, at the same time as the fibre access network deployment, a qualified technician will survey the user's home to determine the best route for the fibre optic cable entry. Once the route has been determined, the specialist will then install the fibre optic cable and connect it to the ONT. Finally, the technician will configure the ONT and test the connection to ensure that it is working properly.

FTTH networks are commonly installed by internet service providers (ISPs) who run the fibre optic cables from their central office to a subscriber's residence. The process mentioned above can be done by burying the cables underground or attaching them to existing utility poles. In some cases, the cables may also be run directly through the walls of a building.

What are the benefits of FTTH networks?

Once installed, FTTH networks can offer users a variety of benefits and advantages over traditional broadband networks. Some of them are faster download and upload speeds, more stable connections, and the ability to support multiple devices simultaneously.

With FTTH, users can easily stream high-definition video, download large files, participate in online gaming without any buffering or lag, and in other data-intensive activities since the main benefit of FTTH is its ability to provide remarkably high speeds, often up to a gigabit per second (Gbps). The high data rates, combined with the low latency that it allows, makes FTTH also metaverse-ready.

Another advantage of FTTH is that it is highly scalable. As demand for internet services increases, FTTH networks can be easily upgraded to support higher speeds and more users. This makes FTTH a great long-term investment for both service providers, investors, municipalities, and government entities.

Furthermore, some have called FTTH "future proof", since it enables numerous upgrades without requiring the replacement of the fibre itself, thus permitting the surrounding infrastructure to be updated.

Since the 1980s, FTTH has expanded to meet the increasing network requirements of the contemporary world. The fact that many fibre cables installed in the 1980s remain in use today is evidence of their adaptability through time.

To sum up, FTTH is a reliable and efficient way to deliver high-speed internet access directly to homes and businesses. With its fast speeds and scalability, FTTH is well-suited to meet the increasing demand for internet services and support the growing number of connected devices

FTTH vs. FTTx, FTTN, and FTTC: differences

FTTH is often compared to other broadband technologies such as FTTx, FTTN, and FTTC. FTTx refers to any broadband network that uses fibre optic cables for part of the connection, while FTTN (fibre to the node) and FTTC (fibre to the curb) are specific implementations of FTTx. In general, FTTH provides the fastest speeds and the most reliable connection.

Fibre to the home (FTTH), fibre to the x (FTTx), fibre to the node (FTTN) and fibre to the curb (FTTC) are all diverse ways of delivering broadband internet access to customers using fibre optic cable.

FTTH is the fastest and most advanced of these technologies, as it involves running a fibre optic cable directly to a customer's home or business, allowing for incredibly fast internet speeds, as well as improved reliability and latency in comparison to other technologies.

FTTx is a more general term that encompasses a range of technologies, including FTTH, FTTN, and FTTC. It refers to any situation where fibre optic cable is used to deliver broadband internet access to a customer, but the specific point at which the fibre cable is terminated can vary.

FTTN and FTTC are similar technologies, however, they differ in where the fibre optic cable is terminated. In FTTN, the fibre cable is terminated at a node or street cabinet, which is then connected to the individual's house or business using traditional copper wire, enabling faster speeds than traditional copper wire, but not as fast as FTTH.

In FTTC, the fibre optic cable is terminated at a point closer to the customer's home or business, such as a curb or sidewalk. As a result of this, faster speeds than FTTN are guaranteed, but once again not as fast as FTTH.

Overall, FTTH is the best and most cutting-edge technology for delivering broadband internet access, as it provides the fastest speeds and best reliability. FTTx, FTTN, and FTTC are all variations of this technology, but they are not as fast or reliable as FTTH.

Is FTTH climate friendly?

Fibre to the home (FTTH) technology is viewed as environmentally friendly for a number of reasons.

First, fibre optic cables are made of glass or plastic, which are both materials that can be easily recycled. In contrast, traditional copper wire cables are not as easily recycled and can end up in landfills. Moreover, fibre optic cables are much thinner and lighter than copper wire cables, which means they take up less space, require less energy to transport, and install. This can help reduce the environmental impact of laying new cables.

In addition to this, FTTH technology allows for much faster internet speeds and more reliable connections than other technologies, which can help reduce the need for multiple devices and multiple connections in a household or business. At the same time, FTTH enables multiple applications which can contribute to reducing the carbon footprint of our activities, remote working and learning being the most obvious examples. Therefore, its implementation helps save energy and reduce the overall environmental impact of providing broadband internet access.

Finally, glass or plastic are durable materials that do not need to be upgraded or replaced, allowing for a very long-life cycle, reducing waste and CO2 emissions coupled with such a network upgrade.

While there may be some environmental impacts associated with installing and maintaining fibre optic cables, FTTH technology is considered to be more environmentally friendly than other broadband technologies.
