ENTERPRISE STRUCTURED CABLING WORKFLOW
Project Management Application
The Project Management Application is a cloud- and browser-
based application that allows a project manager to control the
entire measurement process:
• Define enterprise specific workflows
• Assign tasks
• Develop label templates
• Set up test profiles
• Analyse results
• Manage crews
When finally set up tasks can be assigned to a field technician
and provided via the cloud platform.
NOTE: For further information about the Project Management
Application please refer to the help provided with the application.
Mobile Application
The Mobile Application allows the field technician to download
assigned tasks from the cloud platform (push service) and to
transfer the task to the measurement instrument.
After completing the tasks the results can be uploaded via the
Mobile Application to the Project Management Application on
the cloud platform for further analysis.
NOTE: For further information about the Mobile Application please refer
to the help provided with the application.
Measurement instrument
Measurement instruments that support ESCW (OLTS-85/OLTS-
85P, Certifier 10/40G, TB/MTS-2000) offer beneath the test
application centric Test-Tool mode a Workflow mode. This
Workflow mode allows the use of the ESCW functions like a
structured, guided, and pass/fail-oriented execution of projects
assigned to a specific field technician.
For key benefits of the Workflow mode see “Workflow Mode” on
page 31.

OLTS-85/OLTS-85P LOSS TEST SET
OLTS-85/OLTS-85P Loss Test Set
The SmartClass™ Fiber OLTS-85/OLTS-85P (optical loss test set)
contents high-performance, easy-to-use instruments with a two
or four wavelength light source and a power meter. They are
universal instruments for Tier 1 certification of single-mode and
multi-mode fibers, installation, maintenance, and
troubleshooting. Automate pass/fail end-face analysis for all
fiber types, and gain complete test visibility at both local and
remote ends. Use pre-configured cabling specifications from all
leading manufacturers.
Loss can be measured simultaneously at two wavelengths. Quick
referencing for all built-in wavelengths can be effected
independent of the current measurement mode.
Key Benefits of the OLTS-85/OLTS-85P Loss
Test Set
Test-Tool mode

ISO 11801, and ISO 14763-3 requirements.
• View test setup and results data and edit labels at both local
and remote ends.
• Objective pass/fail testing for fiber end-face requirements.
Workflow mode
• Label list centric approach.
• Guided testing of large number of equal test points with
predefined tests.
• Visual display of measurement progress.
• Quick overview of passed and failed test.
Features
• Multi-mode (850/1300 nm) and single-mode (1310/1550 nm)
adapters for Tier 1 fiber certification (loss/length/polarity).
• Industry-leading P5000i Digital Probe fiber end-face

OLTS-85/OLTS-85P LIGHT SOURCES
OLTS-85/OLTS-85P Light Sources
The SmartClass™ Fiber OLTS-85/OLTS-85P light sources are
professional, versatile, compact handheld instruments designed
for qualification and certification of fiber optic networks.
Carefully chosen combinations of available wavelengths make
SmartClass™ Fiber OLTS-85/OLTS-85P light sources the
optimum choice for link loss testing and characterization of
long-haul, metro, and access telecommunication networks, as
well as for data center and local area network testing.
Single-mode (SM) and multi-mode (MM) – The
all-in-one solution
OLTS-85/OLTS-85P devices that have both single-mode and
multi-mode light sources are the most flexible test instruments.
These instruments are particularly suitable for rental and
measurement service companies.
Fiber inspection ready – Inspect before you
connect
The SmartClass™ Fiber OLTS-85/OLTS-85P instruments are
prepared for fiber inspection. Connection of a P5000i Digital
Probe to the OLTS-85/OLTS-85P enables a technician to perform
best practices fiber inspection and automated Pass/Fail testing
of optical connectors/adapters in order to ensure industry
standard fiber end face quality and cleanliness.
No additional fiber microscope set required – simply plug in a
P5000i Digital Probe.
Report generation – Do it the easy way
Of course, it is possible to make measurement reports with a PC
tool.
FiberChekPRO™ is the ideal tool for generating your report.
Please download FiberChekPRO™ for free on
http://updatemyunit.net.
Rugged and portable
Battery operation with AA dry batteries, or with a rechargeable
Li-Ion Battery Pack ensure a long operating time in the field and
a robust, shock-proof design makes the SmartClass™ Fiber
instruments the perfect choice for optical network field testing,
even under tough conditions.

3 GETTING STARTED
UNPACKING THE INSTRUMENT
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 129.
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 an 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 129).
