Note
CLASS 1 LASER
The plug-in transceivers are approved as laser Class 1 according to IEC 60825-1.
Fiber optic cables that are connected to these optical radiation sources may therefore either
lead into or through hazardous areas that require equipment of the explosion protection level
(EPL) Gb, Gc, Db or Dc.
