BEFORE connecting any signal to the Optical In ports ensure
that sufficient external attenuation is inserted in the signal
path so that the power level is within the 'Operating Range' for
the port. Also ensure that any signal transient condition never
exceeds the maximum stated limit for that 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 instrument's Optical Out connectors.
• Arrange for service-trained personnel, who are aware of the
hazards involved, to repair optical cables.
Laser Warning Symbols
The instrument's connector panel is labelled with the following:
CLASS 1 LASER PRODUCT
CLASS 1 LASER PRODUCT translates as follows:
Finnish - LUOKAN 1 LASERLAITE
Finnish/Swedish - KLASS 1 LASER APPARAT
This label indicates that the radiant energy present in this
instrument is non-hazardous.
Avoiding Optical Receiver Overload
Check that you do not overload the receiver when connecting an
optical transmitter to an optical receiver. This applies to
elements under test and also the receiver input ports. To avoid
optical receiver overload, complete the following:
• Check for Status messages on the instrument display
warning of overload conditions.
• Check the printed output/input power level information on
the connector panel:
a Tx Optical Out ports: Maximum available output power.
