OLT-85/OLT-85P LOSS TEST SET
1INTRODUCTION
OLT-85/OLT-85P Loss Test Set
The SmartClass™ Fiber OLT-85 (P) (optical loss test set) is a high-
performance, easy-to-use instrument with a two or four
wavelength light source combined with a power meter. It is a
universal instrument for singlemode and multimode fibers,
installation, maintenance, and troubleshooting.
Loss can be measured simultaneously at up to four wavelengths.
Quick referencing for all built-in wavelengths can be effected
independent of the current measurement mode. Just connect
the source and power meter with a fiber patch cord.
Loss test sets
A loss test set combines a power meter and a light source in the
same instrument. It is a highly accurate tool and is used to
determine the total amount of loss or attenuation of a fiber link.
With traditional light sources and power meters, the instruments
must either be transferred from one end of the link to the other
or a light source and a power meter are required at both ends of
the link. The technician requires a total of four instruments in
order to perform measurements in both directions. With a loss
test set at each end of the link, tests can be performed in both
directions using only two instruments and without the need to
transfer them from one end to the other.
Operating manual update
Continuing enhancement and further development of the
SmartClass family may mean that this operating manual does
not cover all the latest functions of your instrument.
If the operating instructions about features supported by your
instrument are missing, please visit the Viavi web site to check if

WARNING
Dangerous laser radiation
Laser radiation can cause irreparable damage to eyes and
skin.
The maximum permitted power for the OLT-85 means that the
optical input signals can reach hazard level.
Bear this in mind when using the OLT-85.
JThis device is a Class 1 laser product according to
DIN EN 60825-1:2007.
JAlways be aware of the hazard level of the instrument to be
connected.
JConnect all optical fibers before switching on the radiation
source.
JSwitch off the laser source before disconnecting the optical
fibers.
JNever look directly into the unconnected port of the
instrument, the output of a laser source, or an optical fiber
connected to a source or a system.
JAlways cover unused ports.
JBe aware that the emitted light is not visible.
JHeed the normal precautions for working with laser radiation
and consider local regulations.
WARNING
Explosion danger
Short-circuiting the batteries can result in overheating,
explosion, or ignition of the batteries and their surround-
ings.
JNever short-circuit the battery contacts by touching both
contacts simultaneously with an electrical conducting object.
JOnly use AA size dry batteries or rechargeable batteries.
JMake sure the batteries are inserted with the correct polarity.

3GETTING STARTED
Unpacking the instrument
Packing material
We suggest that you keep the original packing material. It is
designed for reuse (unless it is damaged during shipping). Using
the original packing material ensures that the instrument is
properly protected during shipping.
Checking the package contents
JUnpack the instrument and check the package contents. For
more information see “Included items” on page 92.
Checking for shipping damage
After you unpack the instrument, check to see if it was damaged
during shipping. This is particularly likely if the packaging is
visibly damaged. If there is damage, do not attempt to operate
the instrument. Doing so can cause further damage. In case of
damage, please contact your local Viavi sales company.
Addresses can be found at www.viavisolutions.com.
Recovery following storage/shipping
Condensation can occur if a instrument that is stored or shipped
at a low temperature is brought into a warm room. To prevent
damage, wait until no more condensation is visible on the
surface of the instrument before powering it up. Do not operate
the instrument until it has reached its specified temperature
range and wait until it has cooled down if the instrument was
stored at a high temperature (see “Ordering Information” on
page 92).

UNPACKING THE INSTRUMENT
NOTE: Rechargeable AA batteries will not be recharged in the
instrument. For AA-type rechargeable batteries please use an
external charger.
It is not possible to charge the rechargeable AA batteries or the
RBP2 Li-Ion Battery Pack via the USB interface.
The instrument is powered by the PS4 Universal AC/DC Power
Supply if the PS4 Universal AC/DC Power Supply and the USB
interface are both connected.
Deep discharge
A rechargeable battery that appears to be dead (unit will not
turn on even when connected to external power) may well be in
a deep discharge state. It can be fully charged with the following
charging cycle:
1. Plug in the power cord for 1–1.5 hours.
Battery should be partly charged now.
2. Switch the power on.
If the instrument starts: Let the battery fully charge.
– or –
If the instrument does not start:
Unplug power cord, plug it back in and repeat steps 1 and 2.
NOTE: If the battery is completely deep-discharged, this cycle might
need to be repeated up to 3 times.
General tips on using batteries
• Always handle batteries with care.
• Do not drop or damage the batteries or expose them to
excessively high temperatures.
• Do not store the batteries for more than one or two days at
very high temperatures (e.g. in a vehicle), either separately or
inserted in the instrument.
• Do not leave discharged batteries in the instrument for a long
time if it is not being used.

UNPACKING THE INSTRUMENT
Other basic safety precautions are as follows:
• Do not use PS4 Universal AC/DC Power Supply outdoors or in
wet or damp locations.
• Connect the PS4 Universal AC/DC Power Supply to the correct
mains voltage, as indicated on the rating label.
• Do not allow anything to rest on the power cord, and do not
place the product where people can walk on the power cord.
• Avoid using this product during electrical storms. There may
be a remote risk of electric shock from lightning.
• Do not use this product in the vicinity of a gas leak or in any
explosive environment.
• Do not attempt to service this product yourself, as opening or
removing covers may expose you to dangerous, high-voltage
points, and other hazards. Contact qualified service personnel
for all service.
Environmental protection
Please dispose of any unwanted dry batteries and rechargeable
batteries carefully. They should also be removed from the
instrument if it is to be discarded. If facilities in your country exist
for collecting such waste or for recycling, please make use of
these rather than throwing the batteries out with normal trash.
You will often be able to return used batteries to the place where
you purchase new ones. Any dry or rechargeable batteries that
you purchased from Viavi can be returned to one of our Service
Centers for disposal.
