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 amp=
s going higher and higher. On a recent meter I saw almost .6mW...=20

Any pointers to a document saying 1550nm becomes dangerous at xxxx dbM?

Thanks in advance,

DJ=
