Is it possible to use a Fiber Channel Arbitrated Loop HUB as a Gigabit fiber Ethernet repeater?

The one in question is similar to the one in this link:
http://web.archive.org/web/1998070 [...] escription

Now if I understand correctly, when the Standard for gigabit Ethernet over fiber was created, they made it conform to the existing fiber channel specification (Physical layer). If that is true, then it should be able to act as a repeater using gigabit Ethernet, right? I mean, it doesn’t say anywhere that it analyzes the packets and as long as what’s being sent conforms to the fiber channel’s physical layer specification it should blindly forward the packets, right?

Essentially what I’m saying is that since Gigabit over fiber uses fiber channel’s physical layer, and the physical layer is all a repeater ever deals with, I should be able to use a fiber channel hub for gigabit Ethernet applications. This is my theory, but I need to be sure this would work before I proceed any further.

Thoughts?

it shouldnt be a problem. a hub doesnt do anything but repeat signal, a powered hub usually re-times the impulses and filters noise. cheap ones just amplify the signal.

my computer is so fast, it completes an endless loop in less than 4 seconds!
