WARNING
Invisible laser radiation
Laser radiation can cause irreparable damage to eyes and skin.
Follow the laser safety regulations that apply in your area.
Take note of the laser classification of the individual test module.
Take note of the laser classification or hazard level of the device
under test.
Make sure that you protect yourself and others from exposure to
laser radiation.
Never look into optical outputs of devices or into the plug end
surfaces (free ends) of optical fibers.
Always cover disconnected optical plugs or disconnected optical
cable connectors with protective caps.
Always switch off the instrument and disconnect it from any fiber
optic cables before inspecting or cleaning the optical cable
connectors.
Make sure that the fiber optic cables are disconnected from all
sources of radiation before they are cleaned or inspected and
ensure that they are not reconnected until cleaning or inspection
has been completed.
CAUTION
SFP laser classification
Use only class 1 laser products in the SFP slots.
However, the user is free to use any other SFP transceiver compatible
with the SFP Multi Source Agreement (MSA).
In this case you must observe the laser classification of the
inserted SFP transceiver and its safety instructions!
