[j-nsp] Using Cisco SFP's on Juniper 4500's

[youza fuuccingbitth]

Hello,

We are short juniper copper SFP, but have an excess of Cisco copper SFP's.
Is it possible to use Cisco copper SFP's on Juniper ? A colleague said the
Cisco will work but always show up/up even if nothing is connected. Has
anyone use Cisco copper SFP's on juniper and what was the result?

Thanks
