Safety-Related Electrical, Physical, and Environmental Information
Laser safety
Stinger® FS/Stinger FS+ Getting Started Guide
C-7
Beware of the following potential sources of danger, that will remain despite all
safety measures.
■
Laser radiation from optical transmission systems is in a wavelength that is
invisible to the human eye.
■
Laser radiation can cause damage to skin and eyes.
!
Caution
Although, at present, the transmit power for Class 1 lasers are below
levels known to cause injury to the eye at distances greater than 250mm (10
Inches), direct exposure should always be avoided. Always observe the
information listed below in “Laser warning instructions.”
Laser classifications
The maximum output power of laser radiation depends on the type of laser diode
used. The international standards IEC-60825 or DIN/EN 60825 define the maximum
output power of laser radiation for each laser class in accordance with the
wavelength.
Laser warning instructions
In its normal operating mode, the Stinger Compact Remote unit is totally enclosed
and presents no risk of eye injury. It is a laser Class 1/I product.
The lightguide cables that interconnect various components of a lightwave system
can be disconnected or break, and may expose people to lightwave emission. Also,
certain measures and service procedures may expose the technician to emission from
the laser circuit pack or module during installation and servicing.
Observe the following instructions to avoid exposing yourself and others to risk:
■
Do not look into the end of an exposed fiber or an open connector when the
optical source is on. (Even though viewing Class 1 lasers at distances greater than
250mm (10 inches) will normally not cause eye injury.)
■
Only authorized technicians, who have satisfactorily completed an approved
training course are allowed to perform service, maintenance, and restoration
Table C-6.
