6 Laser safety precautions
These are 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 wavelengths from 1270nm up to 1610nm. 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 fiber pigtails (ends).
Never look directly into the pigtail of the laser/fiber.
Never use microscopes, magnifying glasses or eye loupes to look into a
fiber 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.
Maximum output power 1 : 5 mW
Operating wavelengths: > 1270 nm
