Cox fiber, tuning adapter still required?

I currently live in a Cox area where everything (TV + internet) comes into the house via coax, and a tuning adapter is required to receive all channels.

I'm moving to a new neighborhood where Cox is offering their Gigablast 1GB internet service.

Regardless of what services you sign up for, in this neighborhood, Cox runs fiber to your house, which it then seems to go into an ONT and splits back to coax for TV.

I was curious if anyone had any experience with this, and knew if tuning adapters were required with Cox's new "fiber to the house" setup. I was hoping the fiber gave them enough bandwidth to be able to push all of the channels without needing SDV/tuning adapters.

Thanks!
