Officially all SFP modules have "Commercial operating temperature range:0°C to +70°C", I am not sure about real life, most likely the range is bigger.

Mikrotik's with SFP ports and Mikrotik SFP modules have been on the market for some time now. What are you guys finding with these units in regards to temperature handling. Are they standing up to the temperatures some of our outdoor enclosures on the inside?

I question such things even more with a recent heat related Cloudcore failure 3 months after installation, in a FM station bunker that can get to around 130F on a hot day even with a 15" industrial fan wall vent.
