EMS Wireless will not be responsible for loss of output or reduced output of
opto electronic devices if the customer performs chip mounting, ribbon
bonding, wire bonding, fiber coupling, fiber connectorization, or similar
operations. These processes are critical and may damage the device or may
affect the device's output or the fiber output.
EMS Wireless test reports or data indicating mean-time-to-failure, mean-time-
between-failure, or other reliability date are design guides and are not
intended to imply that individual products or samples of products will
achieve the same results. These numbers are to be used as management and
engineering tools, and are not necessarily indicative of expected field
operation. These numbers assume a mature design, good parts, and no
degradation of reliability due to manufacturing procedures and processes.
This fiber optic laser transmitter contains a class IIIb laser product as defined
by the US Department of Health and Human Services, Public Health Service,
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
