My preference, for the home, would be Active-E. But I do understand the
economics that may support PON, and my position on that has softened
over the years. My service provider delivers their FTTH service to me
via PON, and for the most part, it's been all good.

That said, I was particularly impressed with what CDE Lightband did in
Clarksville, Tennessee, where they deployed their FTTH network with
Active-E using Brocade to over 60,000 subscribers:

If I had to build a consumer broadband network and had the budget (and
owned the fibre) to do so, I'd definitely always choose Active-E:   

In South Africa, we have an access network operator that uses Active-E
primarily to deliver their service, making it perhaps the only FTTH
provider not using PON to do this. I find this quite fascinating.
