Hello, I bought an apartment and want to install Telia fiber optic internet. Since the former owner of the apartment had also installed Telia fiber optic cable, the apartment already has a cable and one box. Yesterday in the Telia salon, I changed my plan to a fiber-optic one and transferred the service in the apartment to myself, since everything is already in the apartment, they only gave me a router. However, when I return and try to connect to the Internet, it turns out that the ONT (optical converter box) is missing, because I only found such a cable in the apartment (photo).
This is a question of who has Telia fiber optic internet, is it possible to buy an optical converter yourself or is it necessary for a Telia engineer to install something special?
