FTTx Architecture: learn what it is and why to use it

Connectivity speed is one of the main factors in the development of cities—no matter which ones or where they are. The faster and more stable the connection, the better the infrastructure conditions. As a result, innovations become more frequent and the use of new technologies improves.

FTTx architecture plays an essential role in this context. After all, these networks use fiber optic infrastructure, which has a lower deployment cost, better efficiency, and takes advantage of existing city infrastructure for installation.

With all this, adopting this architecture is no longer just an option—it has become a necessity. To understand the importance of FTTx networks, how to implement them, and clarify other related questions, keep reading!

What is FTTx architecture?

For a long time, connectivity infrastructures were basically composed of metallic structures. However, this also meant high maintenance needs, a high rate of theft, and limitations in data communication between the provider and the end user.

The acronym FTTx (Fiber To The X) means “Fiber to the X point”—it’s important to note that the “X point” can be any destination and represents certain types of PON (Passive Optical Networking) technologies, the most common being EPON and GPON, which are point-to-multipoint networks.

In other words, FTTx networks extend the reach of fiber optics—whether from the beginning of distribution all the way to the customer’s home, or only along part of that path.

The main mission of this architecture is to replace metallic cabling with optical fiber and, with that, provide a new level of connectivity.

To achieve this, FTTx technology leverages the PON network structure, which is made up of passive optical splitters that allow fiber to be shared among 32 to 128 recipients. This serves more end users at a much lower cost, as it requires less fiber and fewer central office equipment.

Different types of FTTx

FTTx network architectures are divided into two main types:

· Point-to-Point Networks (P2P): These are the simplest and require a dedicated fiber between the distribution channel and the user. The main drawback is the higher cost, which is why they are less commonly used in the market.

· Point-to-Multipoint Networks (P2MP): Their key advantage is reducing the amount of fiber needed to provide high-quality connectivity. In addition, they are passive structures, meaning they only require power at the endpoints, significantly reducing costs related to usage, equipment, and maintenance compared to P2P networks.

Remember when we mentioned that the “X” in FTTx represents a generic destination point? Now let’s explain the main destination types used in this network:

FTTB (Fiber To The Building)

If you live in an apartment building, it’s very likely that you use FTTB. It is a deployment model commonly used in buildings, where the fiber reaches a central point in the building and is then distributed to subscribers.

FTTC (Fiber To The Curb)

FTTC is an implementation where fiber reaches a specific area but stops about 300 meters before the user’s home. The final stretch is then completed with metallic cabling.

FTTD (Fiber To The Desktop)

FTTD is an infrastructure where the connection reaches a computer room, which then distributes fiber to a converter terminal near the user’s desk.

FTTH (Fiber To The Home)

This is one of the most attractive architectures for service providers. With FTTH, fiber is brought directly into customers’ homes. This allows connection speeds to be tailored to customer needs, reaching speeds from 100 Mbps to 500 Mbps.

FTTN (Fiber To The Node)

This is an intermediate step toward full FTTH. In this case, fiber is connected to a cabinet located on a street that may be several kilometers from the user, with the final connection made via copper. It is widely used to provide advanced triple-play telecommunications services.

FTTO (Fiber To The Office)

As the name suggests, this infrastructure is designed for office environments. The connection is made to a central structure and then to a mini switch at the workstation. From this switch (FTTO Switch), data is distributed to its respective destinations.

FTTP (Fiber To The Premises)

This is a deployment type used for optical distribution networks that run from the central office to the end user. Because it offers higher broadband capacity, FTTP is widely used for data, voice, and video solutions.

Advantages of FTTx architecture

There are numerous benefits of FTTx architecture compared to metallic infrastructures. In short, it is faster, more cost-effective, and more stable. The main trend is that optical fiber will replace all traditional types of connections.
To reinforce these points, here are the main advantages of FTTx in detail:

Increased Speed

Latency refers to delays in data transmission, which result in lag and interruptions. With the stability of FTTx, latency is significantly reduced, often becoming imperceptible to users.

Reduced Latency

Latências são os intervalos que ocorrem na transmissão dos dados, o que resulta em travamentos e interrupções da conectividade. Com a estabilidade da FTTx, as latências são significativamente reduzidas, sendo imperceptíveis para os usuários.

Higher Transmission Capacity

High transmission capacity is essential for companies that hold remote meetings or for users with high-demand routines, such as YouTubers and gamers.

Reduced External Interference

Unlike copper infrastructures, FTTx networks are not affected by electromagnetic interference. Additionally, while copper transmission requires electrical networks, FTTx does not, eliminating the need for modems, switches, hubs, and other elements between the central office and the end user.

Easy Installation

Because optical cables are more flexible and smaller than copper cables, FTTx network installations are more cost-effective and easier to deploy, with lower maintenance costs.
