Our solutions

The products D-LINE and W-LINE provide you with the highest speeds in Luxembourg by guaranteeing you the best network performance between your company sites and your data centres.

Which connectivity for which use?


  • Point-to-Point connectivity over end-to-end dedicated fibre to Enterprise sites or Data Centres, ensuring low and consistent latency

  • Suitable for needs requiring a greater number of services, more demanding in terms of performance and with the prospect of evolving over time
    Example: for high bandwidth LAN interconnects (40 GbE – 100 GbE).


  • Point-to-Point connectivity from Enterprise sites to Data Centres via the shared POST network

  • To be preferred for service needs that are limited in number and not highly scalable
    Example: for Ethernet Service type services (from 1 GbE to 10 GbE).
