Safety Precautions
The optical emission from the transmitters used with this product are laser-based
Class IIIb, as are the emission from the optical connector that connects to the
receiver optical port. Class IIIb laser emissions may present eye hazards if improp-
erly used.
NEVER USE ANY KIND OF OPTICAL INSTRUMENT TO VIEW
THE OPTICAL OUTPUT OF THE UNIT.
As always, be careful when working
with optical fibers. Fibers can cause painful injury if they penetrate the skin.
2.8.1
Laser Safety Procedures
1)
ALWAYS
read the product data sheet and the laser safety label before power-
ing the product. Note the operating wavelength, optical output power, and
safety classification.
2) If safety goggles or other eye protection are used, be certain that the protec-
tion is effective at the wavelength(s) emitted by the device under test
BEFORE
applying power.
3)
ALWAYS
connect a fiber to the output of the device
BEFORE
power is
applied. Power should never be applied without an attached fiber output. If
the device has a connector output, a connector should be attached that is
connected to a fiber. This ensures that all light is confined within the fiber
waveguide, virtually eliminating all potential hazard.
4)
NEVER
look in the end of a fiber to see if light is coming out.
NEVER!
Most
fiber optic laser wavelengths (1310 nm and 1550 nm) are totally invisible to
the unaided eye and will cause permanent damage. Shorter wavelength
lasers (e.g. 780 nm) are visible and are very damaging. Always use instru-
ments, such as an optical power meter, to verify light output.
5)
NEVER NEVER NEVER
look into the end of a fiber on a powered device
with
ANY
sort of magnifying device. This includes microscopes, eye loupes,
and magnifying glasses. This
WILL
cause a permanent, irreversible burn on
your retina. Always double check that power is disconnected before using
such devices. If possible, completely disconnect the unit from any power
source.
6) If you have questions about laser safety procedures, please call Force, Incor-
porated for assistance before powering your product. A Sales Engineer or
Applications Engineer may be reached at (540) 382-0462.

*Note: The FC/APC interface uses the “wide-key” standard. This means that the units are
optimized for use with FC/APC connectors that have a 2.14 mm wide alignment key. “Nar-
row-key” FC/APC connectors (2.02 mm) may be used but will produce inferior results.
Standard FC/PC connectors have a 2.36 mm wide key and cannot be plugged into either
unit.
