With very few exceptions (generally caused by bugs, really poorly
written code, or vendor locking gone awry), XENPAKs and other pluggable
optics are are universally supported in any format for any device which
accepts them.

To Juniper's credit, I can't say that I've ever seen them fail to 
support the basic functionality of a pluggable optic, or play any kind 
of vendor locking games. They probably just don't sell LW XENPAKs 
directly, and thus have no reason to list it as supported or unsupported 
in documentation. From that webpage, even in versions of code which 
predated "support" for the SR or ZR optics, the only thing that probably 
wasn't "supported" was displaying the name of the part correctly in the 
CLI.
