Introduction
Laser Product Classification
All optical modules are classified as Class I (non-hazardous)
laser product in the USA which complies with the United States
Food and Drug Administration (FDA) Standard 21 CFR Ch.1
1040.10, and are classified as Class 1 (non-hazardous) laser
products in Europe which complies with EN 60825-1 (1994).
To avoid hazardous exposure to laser radiation, it is
recommended that the following practices are observed during
system operation:
•
ALWAYS DEACTIVATE THE LASER BEFORE CONNECTING
OR DISCONNECTING OPTICAL CABLES.
•
When connecting or disconnecting optical cables between the
test set and device-under-test, observe the connection
sequences given below.
Connecting:
Connect the optical cable to the input of the
device-under-test before connecting to any of the instrument’s
Optical Out
connectors. When connecting to the
Optical In
ports ensure the power level never exceeds the maximum stated
limit for that port. Also ensure that the power level of a signal
applied to an instrument receive port is within the
recommended operating level for that port. Recommended
input operating power levels for each input port are printed on
the connector panel adjacent to the port.
Disconnecting:
Disconnect the optical cable from the
Optical
Out
connector before disconnecting from the device-under-test.
Always close the fiber optic connector dust caps over the laser
aperture.
•
NEVER examine or stare into the open end of a broken,
severed, or disconnected optical cable when it is connected
to one of the Transmission Test Set Optical Out connectors.
•
Arrange for service-trained personnel, who are aware of the
hazards involved, to repair optical cables.
