OF-500 OptiFiber Certifying OTDR
Note
While this manual describes specific operating
procedures for the OptiFiber tester, the fiber test
methods described are provided only as guidelines.
Your test methods may vary.
Overview of Features
The OF-500 OptiFiber® Certifying OTDR (hereafter referred
to as the tester) is a hand-held Optical Time Domain
Reflectometer (OTDR) that locates and characterizes
reflective and loss events in multimode and singlemode
fibers. The tester is optimized for use on the shorter fiber
runs typically installed in premises (building and campus)
networks. Typical test ranges are up to 7 km at 1300 nm for
multimode fiber and up to 60 km for singlemode fiber.
The tester offers the following features:
•
Automated OTDR trace and event analysis help you
identify and locate faults on multimode (850 nm and
1300 nm; 50 µm and 62.5 µm) and singlemode
(1310 nm and 1550 nm; 9 µm) fiber.
•
Displays OTDR results in summary format, as a table of
events, or as an interpretive OTDR trace. PASS/FAIL
results are based on factory-installed limits or limits you
specify.
•
ChannelMap™ function provides an intuitive diagram
of the connectors and segment lengths in a channel.
•
FaultMap™ function provides an intuitive diagram of
connections that might be bad.
•
Optional FiberInspector™ Video Probe lets you inspect
fiber endfaces and save the images.

Warning: Risk of fire, electric shock, or
personal injury.
Warning or Caution: Risk of damage or
destruction to equipment or software. See
explanations in the manuals.
Warning: Class 1 (OUTPUT port) and Class 2
(VFL port) lasers. Risk of eye damage from
hazardous radiation.
Do not put products containing circuit boards
into the garbage. Dispose of circuit boards in
accordance with local regulations.
THIS PRODUCT CONTAINS MERCURY.
DISPOSE OF THIS PRODUCT IN
ACCORDANCE WITH LOCAL
REGULATIONS.
WWarning: Class 1 and Class 2 Laser
Products
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 tester’s
outputs unless a fiber is attached to the output.
•
Do not open the case; no user-serviceable parts
are inside.
•
Do not modify the tester.
•
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.
•
Use only the ac adapter provided to charge the
battery or power the tester.
•
Do not use the tester if it is damaged. Inspect
the tester before use.

OF-500 OptiFiber Certifying OTDR
Users Manual
•
If this equipment is used in a manner not
specified by the manufacturer, the protection
provided by the equipment may be impaired.
WCaution
To avoid damaging the tester or cables under
test and to avoid data loss:
•
Always turn the tester off before removing or
installing a module.
•
Never connect the OTDR port to an optical
source. Doing so can damage the OTDR receiver.
•
Never connect the tester to an active network,
except when using the power meter. Doing so
causes unreliable test results and can disrupt
network operations.
•
If the tester shows an error because the power
reading is too high, immediately disconnect the
source from the tester. The tester is not designed
for measuring higher power levels, such as
produced by CATV, optical amplifiers, and
cellular systems.
•
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.
•
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.
•
Use a Fluke Networks FiberInspector Video
Microscope to periodically inspect the OTDR and
loss/length option’s OUTPUT connectors for
scratches and other damage.
10
•
Read the instructions for splice machines before
using the OTDR to monitor splicing procedures.
The OTDR can interfere with the light injection
detection techniques used by some splicers.
•
To avoid unreliable test results, connect the ac
adapter or replace the battery as soon as the low
battery indication appears.
•
You may use a PC to move or copy test record
(.tst) files from a memory card, but do not
rename the .tst files. Doing so may result in loss
of data.
•
Never remove the memory card while the
memory card’s LED is on. Doing so can corrupt
the data on the card.
•
Memory cards may be lost, damaged, or
accidentally formatted, resulting in data loss.
Therefore, Fluke Networks recommends saving no
more than one day’s worth of test results on a
memory card.
