Ultra-broadband network

POST Technologies has been busy launching an optical fibre network for several years. The first phase saw the Central Offices (CT) connecting with each other. In a second phase, fibre optic technology was brought closer to the inhabitants, up to the secondary distributon frames located in the different cities of the country.

Since 2006, POST Technologies has installed a large number of street cabinets with active transmission equipment (Outdoor-DSLAM) and supplied by optical fibre cables. This has strongly reduced the distance of the copper network between the customer and the transmission equipment. Most households are now connected to VDSL2 equipment at a distance of less than 1200 m.

The third and final phase, "Fibre to the Home" (FTTH), will bring optical fibre inside homes. The ambitious FTTH project was launched in 1997. During the modernisation and extension phases of the network, so-called ‘hybrid' cables were installed, which contain both optical fibre cables and copper conductors. At the start, only the copper pairs were used and the fibre optic cables were scheduled for future activation. Then, at the end of 2008, passive splitters were installed in the hybrid street cabinets. The fibre optic cables could then be connected to the Central Office in a point-to-multipoint network to an optical distribution frame.


Homes will be connected with two point-to-point fibres to an optical distribution frame in a so-called Point of Presence (POP). POST Technologies is currently building new POPs across the entire country.

Professional fibre optic network

Professional buildings will be connected to one or more Central Offices (CT) with the professional "Fibre to the Office" (FTTO) optic network. This means they will be able to take advantage of telecommunications services based on a fibre optic infrastructure dedicated to professional needs.

Professional buildings are often connected to at least two different Central Offices by two separated connections, providing access by fibre optic loop. This also ensures secure access to the telecommunications services of the companies.

The fixed network: In terms of capacity

More than 99% of households in Luxembourg today are connected to the POST Technologies' broadband network. Around 98% of households have access to POST Technologies' ultra high-speed network (≥30Mb/s). Around 94% of households have even access to high-speed services up to 100 Mb/s.

More than 67% of households are connected to POST Technologies' fibre optic network and have already today access to ultra high-speed services of up to 1 Gb/s.

The fixed network: In terms of the length of the cables used

POST Technologies' traditional copper network provides national coverage via more than 8,000 km of copper cables with more than 1,700,000 km of copper pairs.

The hybrid network consists of more than 4,700 km of hybrid cables with more than 98,000 km of copper pairs and more than 85,000 km of optical fibres. The hybrid network was installed in a local sub-loop during the extension and modernisation phases of the network.

The fibre optic network is currently being widely extended. More than 18,000 km of optical fibre cables with more than 1,200,000 km of optical fibres have already been installed. If the fibres of these cables were laid out along the equator, you'd be able to circle the world more than 30 times!
