Your direct test I would expect to fail; pulling the TX fibre will cause the

Yes, the far end. But I meant I connected both TX and RX between two ports.
That made them both come up (of course). But when I pulled just one TX
they both went down.
As far as I understand it, that is expected if autoneg is enabled. If
you pull the TX link on switch A, switch B will see the loss of light,
signal link-fail, and switch A will then put its link down.
Anyway, it sounds like you've covered the obvious things, and if it
works with other vendors, I guess it's something specific to the EX.
Can't help there, sorry.
