[AFMUG] Temperature and SFPs

[Nate Burke]

I was just looking around at 10g SFP's, I saw that the MaxxWave brand 
list 0c-70c as operating temperature, and the Mikrotik and UBNT modules 
list no temperature range at all.  Are SFP's really temperature 
dependent?  I'm more worried about cold than heat.  I had a couple 
edgepoints with 10g Maxxwave modules out over last winter without any 
issues, but it was rather mild.
