The industrial components that are mentioned below, the other version is
usually called consumer... Guess what Ubiquiti buys?

The MikroTik CRS212-1G-10S had a design flaw where the SFPs were pressed
right against each other, and there was no cooling fan. As a result, in
warmer temperatures I've seen a full load of SFPs get up to 80+ degrees
celsius, too hot to handle by hand, and causing packet loss. Other than
that I don't recall seeing SFP issues caused by overheating.
We had a customer who asked that the installers put their GPON ONU in an
unheated basement for some reason. Even though Ubiquiti rates their CPEs
as functioning down to -10 C, the customer saw it losing connectivity on
the coldest days (-30 outside) when the nearby thermostat was still +5
C. They fixed it by putting a heater nearby.

with SFPs the temp ratings have a double meaning. The ones rated
industrial actually have better components in them so they tend to
have a better chance of survival in any situation. I wouldn't
necessarily worry about the low end as much as the high end. Its not
that hard for a switch in an enclosed boxto get very hot if not
vented. especially with a few sfp ports in it.

What about 10/100/1000 SFPs? Is it worth ordering the custom ones
from FS.com to get the temperature specs down to -40 C?____

We’re deploying some CCR1036 at sites that get really cold in
winter and using the 4 SFP slots for additional GigE ports might
save having to add a switch. Or maybe with self-heating the SFPs
won’t actually get below 0 C? That seems optimistic when it’s -25
F in the unheated building.____

Ok so the best way I have found is to order the custom ones.____

If these are going in a Mikrotik that is not in an environmentally
controlled space you will want to choose the -40 to 85c option
that you will probably have much better results. The normal
Mikrotik SFPs I believe are 0 to 70.____
Yes they take some time extra time to be delivered typical time
frame is 3-5 weeks. As well it might cost you %25 more thanks to
the import taxes, but in my mind $3 on a $11 sfp is worth it.____

What about 1G SM/MM SFP?
I get so fed up with mikrotik modules that have temp,speed or
just plain stop working
