searching alibaba for new gear is truly an eye-opening experience...
I am under the impression however, that SFP+ is needed for gig

The specific question was what form of conduit (earth burial) would be sane?
This would be a ground burial thing where I would be comfortable with
ground buriable ethernet, no conduit (it's a forest), but fiber looks more

This is a campground in california. Amusingly, a few hours after we started
eagerly discussing digging up the ground, it started pouring rain. I'm going
to put "discuss fiber deployment" into my bag of drought-ending tricks...

I saw that a fiber blower box was 6k. There seem to be daily rentals
