This conversation has gone places I didn't expect. Leo, that card is pretty cool, but for a few hundred $$ more, you can get a light meter (if someone is smart enough to use the card...)
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.
Does anyone *use* any eye protection (other that not looking at the light, turning off the light etc) -- I mean like protective goggles, etc, when doing simple things like adding/removing patch cables from an SMF patch panel. I get that if you *know* the gear you are using has a Class 3 laser on it, you should be careful... but when you are patching it into a building's cable plant and some schmuck is patching the last leg in for you (or has pulled it accidentally, etc).. um, "don't look at it" is our community's BCP?
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. -- Richard A Steenbergen <ras () e-gerbil net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC)
