So to give more detail, a laptop and Cisco switch connect 
fine.

But a Tejas SDH box does not. I'm thinking it's because the 
Cisco copper SFP can run only at 1Gbps, while a properly 
coded Juniper one (or a Cisco one that will work) supports 
tri-rate, given the Tejas did not do anything faster than 
100Mbps.
