Bulk Fiber Optic Cable for retrofit

Would this bulk fiber cable be appropriate for a run from the AT&T demarc to my closet where the router is? That is, will the AT&T fiber tech be happy seeing this cable or will he be put off? Or worse yet, refuse to use it for some reason? I want to avoid running something with preinstalled connectors as it will be harder to run through the walls and would rather the tech take responsibility for the connectors.
