There are erbium doped raman lasers with output of up to 10 watts
continuous wave, they are (obviously) class 4 devices and are considered
hazardous.
3r and 3b emitters shouldn't be directly exposed to the eye, and carry
an appropriate warnings. the 10-80km stuff should all be 1 or 1m and

At what power level do DWDM systems become dangerous to work near (i.e. not
staring into any optics, using light meters, etc)? I never see technicians on
inside DWDM systems using eye protection, but I see power levels of amps going
higher and higher. On a recent meter I saw almost .6mW...

Thanks to all for the on and off list replies, they've been helpful.
We get full BGP routes from all upstream connections (currently they are all
different providers). The upstream bandwidth is cheaper at site 2 than at
site 1 and the private backnet connection is a fixed cost so when previously

On the 6500, this seems to have been changed somewhere in the 12.2SX line.
Hello. Nanog

But, now I realize that the default ibgp interval of Cisco is 0 second.
