Carrier equipment in outdoor shelf - LWL LC Connectors & humidity

Hi there,

i need to install some metro Ethernet FTTC backhaul equipment in some (insulated but not AC'd) outdoor shelves.

I'm already fin withe the Devices itself (e.G. Cisco ASr920 or Juniper ACX) that are able to operate in env Ranges between -40°C and +70°C.

My only concern is the LC connection between fiber and SFP. The installation will be in northern Germany where we have 4 months of hot and dry summers and 8 months of wet and foggy Fall/Winter/Spring/whatever.

As we all know the fiber material itself dons't like humidity. Is this a problem for the Connection between SFP Optic and the tip of the LC connector? (sry for not finding the correct words)

I did some research (googled) for LC Connectors that are e.g. IP55 rated, but only found LC/LC Couplers within an insulated container, noting regarding the Connection between SFP and fiber itself.

Has anybody knowledge in this point and can share his experiences?
