A:AnswerUnfortunately I can't answer your question about using this cable modem/router with regard to fiber optics connection. We have regular cable internet service. I can tell you the technician recommended getting this Netgear unit over what the cable company provides. It gives the best spectrum of signal available for the cable company.
A:AnswerThis is a good cable modem and will work for cable and internet. It does not have a jack for phone if your phone service is the internet phone type (VOIP).
A:AnswerI upgraded to this router as I work from home and needed higher upload speed and this works great for me. Has not dropped Zoom calls or even when I'm moving files. Works great. I live in a single home in a development. Good luck.
