Chapter 2 Safety
Chapter 3 of this manual is a quick start guide. Prior to using the quick start guide or operating the
equipment in any way, it is highly suggested the user reads all safety information
This product has been designed and tested in accordance with the Manufacturer’s safety standards, and
has been supplied in a safe condition.
This document contains information and warnings that must be followed by the user to ensure safe
operation and to maintain the product in a safe condition. Failure to follow these safety warnings, can
result in damage to the instrument or harm to the user.
Warning
Personnel should always be aware when working with fiber optic test equipment that active fibers
may be present and therefore infrared optical energy may be present.
Warning
Never look directly into the end of a connected fiber optic cable or fiber optic adapter of test
equipment, to do so could expose the user to laser radiation and could result in sever personal injury.
Warning
To Prevent Fire or Shock Hazard
● Do not install battery types other than those specified by the manufacturer
● Do not use the charger without the batteries installed
● Do not expose the battery charger to rain or excessive moisture
● Do not use the AC adapter when there are signs of damage to the enclosure or cord
● Ensure that you are using the correct charger for the local line voltage
● Do not use any other charger than the one provided with this instrument

Failure to follow these cautions statements may void the warranty of this equipment.
Caution
Fiber-optic connectors are easily contaminated or damaged. The connection to the PRO-8CW-35SM
is a physical contact type of connection and dirty or damaged connectors may impair the instruments
capabilities at minimum and at worst result in the need to return this unit to the factory for expensive
repairs. Prior to making any connection to the unit, ensure that all proper cleaning procedures have
been followed. Use UPC Finish Connectors Only!
Caution
The PRO-8CW-35SM-CWDM maximum power per channel is +5dBm and the Maximum Composite
power is +23dBm. Attempting to test greater power levels will cause damage to this instrument.

Chapter 3 Introduction
Thank you for purchasing the PRO-8CW-SM35 multi-tasker, the world’s first handheld test and
measurement product dedicated to assist you with installation, commissioning and maintenance of the
next-gen fiber optic networks. If you’re working with upgrading an overburdened network with additional
optical channels or installing the latest generation of multichannel high bandwidth fiber links, the multi-
tasker will assist with meeting your test and measurement needs quickly and efficiently.
The PRO-8CW-SM35 includes the latest extended dynamic range, high resolution Optical Time Domain
Reflectometer (OTDR) technologies as the base platform. As with all of PRO’s newest developments, we
have incorporated the standard features including Instant-on, autotest and immediate event analysis for
fast and trouble free visibility of network distance and loss measurements. Also this instrument includes
the standard capabilities of the stabilized singlemode light source with autowave capability, the matching
autowave broadband power meter to complete the Loss Test Set (LTS) function, a visible fault locator
(VFL) source for nearby fault isolation and fiber identification, and the video scope option for end face
analysis. New to the PRO-8CW-SM35 is the inclusion of the 8 channel ITU grid multi spectrum (OSA)
power analyzer for simultaneous measurement of the upper 8 CWDM wavelengths utilized in the latest
high bandwidth networks.
The multi-tasker provides a startup menu to select from the OTDR, VFL, LTS, SCOPE, and OSA function
immediately upon energizing. This feature is coupled to each instrument for immediate analysis of
important features of your link. Before connecting the instrument to your fiber under test, it is good
practice to examine the optical patch connectors with the optional high resolution 200x or 400x video
scope probe and collect an image to attach to your link documentation. For basic link analysis the OTDR
can then be connected and an autotest can immediately provide link loss and distance results on single
mode fiber at the popular 1310nm and 1550nm wavelengths. The construction mode can be selected to
automatically collect and file both fiber signatures.
The on-board Loss Test Set completes the standard package of documented results necessary to
commission a system, or can be utilized for pass fail analysis of network power throughput. The
advanced autowave feature is a must to improve the efficiency and reliability of measuring at both
1310nm and 1550nm radiation, but as a broadband power meter it is calibrated for system end to end
loss analysis at all popular fiber optic wavelengths with your sources.
For commissioning or troubleshooting a multi-wavelength system, the 8 channel CWDM can be utilized
at various points to detect proper power levels from each source and appropriate add/drop connectivity
settings at each adjustable node on the network. The channel analyzer provides immediate real time
power measurement results of all 8 channels from 1471nm to 1611nm simultaneously and also analyzes
and displays statistical measurements at each ITU grid channel. Of course documentation of all these
results is accomplished at the push of a button.
PRO has many advanced measuring instruments for use with multiple wavelength multimode and
singlemode systems from CWDM wavelength OTDR analyzers, DWDM MiniOSA devices, DWDM Tunable
Laser sources, Variable Optical Attenuators, Loss Test Sets, Video Scopes, as well as PON OTDRs with
1625nm active out-of-band coverage. Please enjoy the use of your new PRO-8CW-SM35 multi-tasker, and
again thank you for considering PRO. Please follow the next section’s simple startup instruction to get
right to work with your PRO test and measurement equipment.
