I have had it since 2017, though they upgraded it to 10g a year or two ago. It’s not vapor ware. It’s just that $8,000 doesn’t buy you much distance (I think it’s 1/3 of a mile from the nearest fiber node).
Oh I know it definitely exists, it’s just so far from residential grade and costs like 5% of what it would cost if you had a business. Strange product.
I’m banned from upgrading beyond gigabit because my wife knows that I’d have to run fiber through the house so it’s all beyond my ability anyway. I’m jealous.
