Safety Information
WWarning
*
To avoid possible eye damage caused by
hazardous radiation and to avoid possible fire,
electric shock, or personal injury:
• Never look directly into optical connectors. Some
sources produce invisible radiation that can
permanently damage your eyes.
• Never run any tests that activate the OTDR or VFL
outputs unless a fiber is attached to the port.
• Do not use magnification to view the optical
outputs without proper filtering.
• Use of controls, adjustments, or procedures not
stated herein might result in hazardous radiation
exposure.
WCaution
To avoid damaging the tester or cables under test,
to avoid data loss, and to ensure maximum
accuracy of test results:
• Turn off the tester before attaching or removing
modules.
• Leave the module bay covers in place when a
module is not installed.
• Use proper cleaning procedures to clean all fiber
connectors before every use. Neglecting this step
or using improper procedures can cause unreliable
test results and may permanently damage the
connectors. See page 7-8.
• Cover all connectors with protective caps when
not in use.
• For modules that support two wavelengths,
never run a test with a fiber connected to the
unused port. Reflections from the fiber can
affect measurements on the port being used.
• Never connect the OTDR ports to an optical
source. Doing so can damage the OTDR receiver.
• Never connect the OTDR to an active network.
Doing so causes unreliable test results and can
disrupt network operations.
