I have had more problems with low temp than high over the past 40 years. From: Trey Scarborough Sent: Tuesday, May 14, 2019 3:41 PM To: [email protected] Subject: Re: [AFMUG] Mikrotik Fiber SFP+
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.

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.

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.
