Laser Safety
Safety of Laser Products
DEV Systemtechnik recommends to follow the governing standard of the
country where the product is operated, to assure regulatory compliance, and to
provide the necessary safety programs to protect the operators and other
persons who get in contact with the product.
It is recommended to power down the chassis in which the optical modules are
applied while working on the optical fiber wiring.
The optical modules operate with light at a non-visible wavelength. Highest
caution has to be taken, especially with EDFA optical amplifier modules and
with optical transmitter modules, since they produce laser light that is capable
to harm the human eye!
All optical connectors have to be equipped with the appropriate protection
cover if no optical fiber is (to be) connected to an optical module.
Direct exposure to the beam is to be avoided, i.e. do not look into
unterminated optical ports or at fibers that connect to unknown sources.
