6 Laser safety precautions
Guidelines to limit hazards from laser exposure.
All the available EO units in the Flashlink range include a laser.
Therefore this note on laser safety should be read thoroughly.
The lasers emit light at 1310 nm or 1550 nm. This means that the human eye cannot see the
beam, and the blink reflex cannot protect the eye. (The human eye can see light between
400 nm to 700 nm).
A laser beam can be harmful to the human eye (depending on laser power and exposure
time), therefore:
Be careful when connecting / disconnecting fibre pigtails (ends).
Never look directly into the pigtail of the laser/fibre.
Never use microscopes, magnifying glasses or eye loupes to look into a fibre
end.
Use laser safety goggles blocking light at 1310 nm and at 1550 nm
Instruments exist to verify light output power: Power meters, IR-cards etc.
Flashlink features:
All the laser module cards in the Flashlink product range, are Class 1 laser products
according to IEC 825-1 1993, and class I according to 21 CFR 1040.10 when used in
normal operation.
More details can be found in the user manual for the FR-2RU-10-2 frame.
