[HECnet] ONT?

I'm moving in a few days and am trying to understand what to do about connectivity without drowning (in advertising or whining). I currently have FIOS and had ordered it so that I had a separate Optical Network Terminal (ONT) and router.  I plugged my own router into the ONT and the FIOS router into my router and all has been well. The Internet provider at the new location is Optimum Online which previously had been a lot easier to deal with than FIOS as you could just plug into the cable modem or get your own.  Naturally, I was provided with a combo ONT/Wireless/Router solution that just isn't going to cut it.  I'm trying to search for an ONT, but am getting deluged with the usual stream of noise, junk and advertising.  For example, I'm getting Optical-Ethernet converters, which I don't think are what I want. Can anybody point me at a few ONT-only solutions that don't come with all the extra garbage, don't do NAT, Etc.?  Or some kind of good introductory information without all the blinking ads?
