Title
OpenNet - Vi binder branchen sammen
Description
Vi hjælper vores partnere med at samarbejde via en moderne IT-platform. Vi sikrer en høj grad af dokumentation, velbeskrevne processer og fælles rammeaftaler. Det skaber genkendelighed og synergi, når du som tjenesteudbyder vil tilgå et nyt fiber- eller hybridfibernet. Når netselskaberne åbner nettene, får slutkunderne flere valgmuligheder og større værdi af deres fiberforbindelse. Vi er stolte af vores løsning og vores plads i markedet.
