No, the one misleading here is you. "Pure digital signals"? LoL, do I pour holy water on my digital signal and make it pure?
What you meant to say was, HDMI is a digital signal however
it is carried over a analog medium, copper.
Signals sent over copper, in long distances, tend to weaken. The problem with copper is incoherent when it comes to fiber which can travel long distances without signal degradation.
A passive HDMI cable made of fiber maintains it's signal for a good 100m whereas our current HDMI cable, made of copper, is good for 10m before signal degradation, some lower quality cables will start exhibiting problems before hitting the 10m mark.
Some of you may ask, why don't they made HDMI cables out of fiber? They can, but then everyone of you here will whine and cry like a baby because of the high cost of fiber.
