Warning
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.
W
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.
*
Caution
•
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.
•
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 port 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.
•
Avoid touching reflective surfaces (such as
metal) to the end of a fiber cable plugged into
the OTDR when the OTDR is operating. An open
fiber connector end face has about a 4%
reflection. Holding a reflective surface near the
connector end face may cause much greater than
a 4% reflection, which may damage the
photodetector in the OTDR.
