We have been leasing the free transmission capacity in fiber-optic cables
– known technically as dark or unlit fiber – to our customers since 1996, including mobile telephony providers, cable network operators, computer center operators, and other commercial customers. Our fiber-optic cables comply with standard G.652 defined by the ITU (International Telecommunication Union), and boast very favorable mechanical and optical properties – for example low attenuation and optimum parameters for light dispersion. Further benefits of our network include its high availability, which is an impressive 99.99% – far exceeding the standard level in the sector. We therefore ensure the optimum conditions for fast and secure data transmission.
