When I was designing for Carlson, we discovered cold is always the enemy, not
heat.

We have a rural tower site where the owner has a few houses on the property,

But.... with the size of the property and the tower being a big metal
structure, that caused some voltage / ground imbalances that fried gear at the
houses after storms, I believe even through surge supressors (hich are made to
protect against single high-voltage direct strikes).
We put in some electrical isolation using copper-fiber-copper converters /
switches at the tower, those worked until the winter: when it got to -30
outside the FiberStore SFPs were unhappy.
Does anyone have good cold-weather solutions? Or were we just unlucky with
those SFPs and should try something else in the cold?
