Food and Drug Administration. This laser product complies with 21 CFR,
Chapter I, Subchapter J of the DHEW standards under the Radiation Control
for Health and Safety Act of 1968. The laser module certification label is
located on the equipment enclosure and it also shows the required DANGER
warning logotype (as shown below).
The EMS Wireless laser products are used in optical fiber communications
systems for radio frequency and microwave frequency analog fiber optic
links. In normal operation, these systems are fully enclosed and fully
shielded by the hermetically sealed laser metal package. Laser bias current
is limited by the internal control circuitry. The transmitters are coupled to
glass fiber and have 1310 nm optical output wavelength with typically 0.5 to
20 mW output depending on the model. The optical radiation is confined to
the fiber core. Under these conditions, there is no accessible laser emission
and hence no hazard to safety or health.
Since there is no human access to the laser output during system operation,
no special operator precautions are necessary when fiber is connected to the
transmitter and receiver. During installation, service, or maintenance, the
service technician is warned, however, to take precautions which include not
looking directly into the fiber connector or the fiber which is connected to the
fiber connector before it is connected to the fiber optic receiver. The light
emitted from the fiber optic connector or any fiber connected to the
connector is invisible and may be harmful to the human eye. Use either an
optical power meter or an infrared viewer or fluorescent screen for optical
output verification. All handling precautions as outlined by the FDA and
ANSI Z136.2 and other authorities of class IIIb lasers must be observed.
Do not attempt to modify or to service this Product. Contact the EMS
Wireless Customer Support Department for a return authorization if service
or repair is necessary.
