[c-nsp] 10GE sanity check

[Justin M. Streiner]

I'm just looking for a quick sanity check here on 10GE optics.

A 10GBASE-LX4 xenpak or X2 module will not talk to a 10GBASE-LR module, 
correct?  I'd test this assertion in my lab, but I don't have a spare LR 
module at the moment.  From what I've read of the coding and transmission 
specs for both types of optics, they wouldn't seem to be compatible, but I 
could be wrong :)  CCO doesn't seem to have much info on module-to-module 
compatibility, probably because they assume the optics will be the same at 
both ends, but vendor differences in this case make that impossible.

Thanks in advance
