I had (accidentally) SFP 1000BaseLX/LH and 1000BaseZX talk to each other

their different wavelengths (!).
Although everything worked fine (passing traffic through) for some minutes, i
replaced one of the
SFPs in order to be sure i won't meet any problems in the future.
In a case like that, you could see problems over time because the laser in
the ZX SFP could overload the receiver in the LX one, depending on the
cable distance between the two units.

It should not work as both have different encoding and no of wavelengths.

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
