The Reach of Fibre Optic Networks
For internet users, the speed of data transmission on the so-called “last mile” is crucial. In the past, it was common for optical fibres to be extended only as far as the local network operator’s distribution point, from where the data was transmitted further via copper cables.
However, due to the rising demand for fast internet, there are increasing efforts to extend optical data transmission with optical fibres to the end customer. In this context, the FTTX classification is used to describe the degree of fibre network expansion.
What is FTTX?
FTTX is a collective term that covers various connection variants in the field of fibre optic technology. The X in FTTX stands for different endpoints such as Home, Building, Curb or Node, depending on how far the fibre optic cable is integrated into the network architecture. These variants have in common that they enable the use of fibre optic cables to provide high transmission speeds and large bandwidths for broadband services. The choice of the specific FTTX variant depends on the requirements of the respective application area, the technical possibilities and the economic framework conditions. The roll-out of FTTX networks creates a future-proof infrastructure that supports the increasing demand for fast internet and modern digital applications.
Typical expansion stages of fibre optics
- Fibre to the Node (FTTN) = Up to the distribution cabinet
- Fibre to the Curb (FTTC) = Up to the pavement
- Fibre to the Building (FTTB) = Up to the building
- Fibre to the Home (FTTH) = Up to the home/office
- Fibre to the Desk (FTTD) = Up to the desk
Other names for fibre optic extension stages
Please note that this is an extension of the above list of different connection types used in connection with fibre. Each type of connection has specific characteristics and areas of application, which may differ depending on the infrastructure and requirements. The following terms are less commonly used but are still worth mentioning.
- Fibre to the Premises (FTTP) = Up to the property (similar to FTTH)
- Fibre to the Factory (FTTF) = Up to the factory
- Fibre to the Mast (FTTM) = Up to the mast
- Fibre to the Last Amplifier (FTTLA) = To the last amplifier
- Fibre to the Office (FTTO) = Up to the office (similar to FTTH)
- Fibre to the Wall/Fibre to the Workgroup (FTTW) = Up to the wall/workgroup
- Fibre to the Antenna (FTTA) = Up to the antenna
- Fibre to the Cell Site (FTTCS) = Up to the cell site
- Fibre to the Distribution Point (FTTdp) = Up to the distribution point (similar to FTTC/FTTN)
- Fibre to the Loop (FTTL) = Up to the loop
- Fibre to the Telecom Enclosure/Fibre to the Zone (FTTE/FTTZ) = Up to the telecom enclosure/zone (despite similar designations, do not belong to the FTTX group of technologies)
