Maybe we should wait and see what Randy has available in the way of
Juniper parts.  If he doesn't have anything readily handy then Leon
could possible seek clones from a place like Moduletek (located in
Shenzhen) and get something suitable - like a  1000BASE-EX or
1000BASE-ZX.   Or I could probably bring something with me.  I plan to
arrive on the 24th.
