Laser safety instructions
Observe the following instructions to avoid exposing yourself and others to risk.
Read the relevant descriptions in the manuals before taking equipment into operation
•
or carrying out any installation and maintenance work on the optical port units, and
follow the instructions. Ignoring the instructions can result in exposure to dangerous
radiation.
Do not view directly into the laser beam with optical instruments such as a fiber
•
microscope, because viewing of laser emission in excess of Class 1 limits significantly
increases the risk of eye damage.
Never look into the end of an exposed fiber or an open connector as long as the optical
•
source is still switched on.
Ensure that the optical source is switched off before disconnecting optical fiber
•
connectors.
In the event of doubt, check that the optical source is switched off by measuring with
•
an optical power meter.
When connecting fiber loops between the IN and OUT ports on optical circuit packs,
•
always connect to the IN port first and then the OUT port. This will prevent any optical
radiation from being present at the fiber end.

Electrostatic discharge ESD considerations

ESD precautions
Industry experience has shown that all integrated circuit packs can be damaged by static
electricity that builds up on work surfaces and personnel. The static charges are
produced by various charging effects of movement and contact with other objects. Dry air
allows greater static charges to accumulate. Higher potentials are measured in areas
with low relative humidity, but potentials high enough to cause damage can occur
anywhere.
