POST Luxembourg first laid FTTH in 1997, as part of a hybrid copper and optical fibre access network. During new constructions, modernisations of public networks, streets or the transformation of overhead cable network to an underground network, POST deployed hybrid cables (with copper pairs and optical fibres) to the customer instead of only copper cables. At that time, only the copper pairs were used and the fibres remained dark for later usage. It was only in 2008 that a programme was started to activate the dark fibres (splitters were installed in the network and the hybrid street cabinets were connected to the central offices). By the end of 2010 POST had connected approximately 18 % of the households to its point-to-multipoint (P2MP) GPON network. In order to prepare for higher broadband network capacity, it was decided to move to a point-to-point (P2P) architecture and provide every customer with four fibres, two of which are connected to an optical distribution frame. In 2010, POST Luxembourg started with the deployment of an Open Access Point-to-Point FTTH network on a large scale. As incumbent, POST can fully reuse a large duct network which otherwise could have been only reused partly. With ongoing FTTH P2P deployment, the existing P2MP infrastructure will be transformed in a P2P topology. Today Luxembourg has one of the regions most far-reaching and advanced FTTH deployment programmes with more than 50 % of the households connected by the end of 2015.
POST Technologies is deploying an Open Access, multi-fibre network which is technology neutral. Per customer, 4 fibres are deployed where 2 are connected end to end from the customer to the POP (Point of Presence). The other two fibres remain as a reserve in the first jointing chamber but could be connected, if required, at a later time. Telecom operators have the possibility to access the customer's fibres at the POP. As the fibre network from the POP to the customers is a point-to-point architecture, operators are free to choose the technology they want to install in the POP (P2P Ethernet or GPON if splitters are installed inside the POP). For its FTTH project, POST Technologies has developed a modular POP design. Beside its existing central offices, new POP buildings will be constructed in order to further reduce the distance to the customers and to reduce the concentration of fibre cables which will have a positive impact on restore times in case of failures. Furthermore the construction of new POP’s will enable POST to abandon different legacy central offices (or parts of them) which are oversized for the future All-IP next generation networks. The size of the POP depends on the region’s specifications and hosts between 500 and 3000 customers.
