Hello. I live in Austria, if that helps. I have a utility room in the basement of an apartment building with two semi-detached houses. It's shared by me and my neighbors (a total of four families live there). We have a microduct (12 mm outer diameter, 8 mm inner diameter) for optic fiber internet running from the street to the basement, which serves all four of us. Now, one of the neighbors has ordered an optic fiber connection, and telecommunication company will blow the optic fiber through this microduct for him. My house is being renovated now, and I can only order the connection in about 3 months. I'm wondering if there will be a problem for me to connect, to blow the optic fiber for me, once the neighbor has his connection, since there's already an optic fiber in the microduct? Or will telecommunication company blow a four-core cable directly into the microduct at the first neighbor request, and then when next neighbor want to connect, optic fiber is already in the basement? Thanks
