I don't think that's quite the right way to phrase it.
What type of twisted pair were you using and/or what sort of setup did you
try? How well did

The Thunderbolt has no problem driving a 100 feet 50 ohm coax cable, aside
from the obvious impedance matching problem (the TB has maybe 5 ohms output
impedance), so I am not sure in what context that remark would apply.

Yes, of corse twisted pairs can handle fast signals. Gigabit Ethernet
over cat-5 cable is a good example.
What I meant when I wrote the below is that a bare t-bolt PPS output
can't drive 100 feet of cat-5 cable when the far end is connected to
to typical 74LSxxx t/l chip. The pulse get smeared.
I don't think the problem is with the tbolt, see

There is a picture of the tbolt driving 50 feet of average quality 75 ohm
cable.
With the right termination, and if the cable is good enough, there should be no
problem.
If the cable is
