They don't have a field in the MLS for that, but most people put the description FTTH in. There are quite a few communities with FTTH in the Wash DC metropolitan area that is not FIOS. Openband is one of them serving my house. The 100M fiber comes into a transition network converter and then to a Netgear. I doubt that any house would have FTTR (rooms).
