It will maintain that over a lot longer..

Which "it"? 100BaseT is speced to 100 Mbps at 100 m, it ain't going
to stop at 100 m and 1 mm. B-)

I THOUGHt gigabit was less however

but it seems you are in fact right!

On Cat5e as well. I looked at this and got moderately confused as
there is afir bit of conflicting information out there, when flooding
this place with network and coax. Decided that Cat5e is good
enough(*) and less finickity about being pulled twisted snagged and
kinked etc when installed by a spark rather than a network
installation bod who ought to know how to treat the cable...

(*) After all the data only comes off a bluray disc at about 50 Mbps
and SDI lives on coax.
