We use SFP Modules outdoor in Switches with extended temperature Range.
What is the temperature range for the Mikrotik SFPs?
SFP DDM:
Identifier SFP transceiver
Connector LC
SONET Compliance N/A
Ethernet Compliance 1000BASE-LX
Vendor Name Mikrotik
Vendor OUI 000000
Temperature 69.01 (°C)
Voltage 3.32 (V)
TX Power -5.40 (dBm)
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.
Ours are not as hot…
a bit higher then the mainboardboard temp…
