JNPR actually claimed that this problem was going to be fixed on 10.4R7
(PR665918, by you). I got such claim in ticket 2011-0725-0041.
I've heard elsewhere that it has not been fixed. I don't care any more,
sourced enough methode cuSFPs from flexoptix.
MX80 experiences this same problem with with even JNPR optics for ISG and
SRX at least. It boggles the mind vendor would internally want to use
different optics for different vendors, seems losing bet.
