    Now if only you could train people to use them... If I had a nickel for
    every time an Equinix tech has told me I'm sending them a +67dBm signal
    I'd be able to actually buy the laser to do that.

    Come on, the closest thing to a dangerous laser you're going to find in
    most colos is the laser pointer built in to the vendor pen schwag you
    picked up at the last beer and gear. The class 3 lasers are few and far
    between, and copiously labeled when you do come across them. Spend 5
    minutes teaching people what the laser classes and how how to read the
    label.
