Accessing the Users Manual
This guide provides basic information to help you get started
using the FIBER QUICKMAP Multimode Troubleshooter. For
additional information, see the FIBER QUICKMAP Multimode
Troubleshooter Users Manual on the Product CD.
Safety Information
Warning: Class 1 Laser
To prevent possible damage to your eyes caused by
hazardous radiation:
•
Do not look directly into optical connectors. Some
optical equipment emits invisible radiation that can
cause permanent damage to your eyes.
•
Do not turn on the troubleshooter unless a fiber is
attached to the port.
•
Do not use a magnifying device to look at the optical
outputs without the correct filter.
•
Use of controls, adjustments, or procedures that are
not in this manual can cause exposure to hazardous
radiation.
Caution
To prevent damage to fiber connectors, to prevent
data loss, and to make sure that your test results are
as accurate as possible:
•
Do not connect APC connectors to the troubleshooter.
An APC connector will cause damage to the fiber
endface in the connector on the troubleshooter.
2
FIBER QUICKMAP Getting Started Guide
•
Use only patch cords that comply with GR-326-CORE
specifications and have UPC connectors. Other patch
cords can cause unreliable measurements.
•
Use the correct procedures to clean all fiber connectors
before each test. If you do not do this or if you use
incorrect procedures, you can get unreliable test
results and can cause permanent damage to the
connectors.
•
Put protective caps on all connectors when you do not
use them.
•
If you use the LC adapter: When your work with the
LC adapter is completed, replace it with the SC adapter
and put the protective cap on the SC adapter.
•
Do not connect the troubleshooter to a network that
is on. If you do, the troubleshooter can cause problems
in the network.
•
If ACTIVE LINE blinks, immediately disconnect the
troubleshooter from the fiber. Optical power levels
more than +7 dBm can cause damage to the detector
in the troubleshooter.
•
The troubleshooter senses optical signals only at
850 nm. If there might be signals at other wavelengths
on a fiber, use a different instrument to make sure that
the fiber is not active before you connect the
troubleshooter to the fiber.

850 nm optical signal on the fiber. If there is an 850 nm
signal stronger than -15 dBm on the fiber, ACTIVE LINE
blinks and the troubleshooter will not do a test.
The digits show the fiber length in feet or meters.
Shows when you look at the setting for the backlight
timer. The setting is in seconds.
