Manual included on the OV-1000 CD-ROM.
•Electronic test equipment is exempt from Part 15 compliance (FCC) in the
United States.
•Electronic test equipment is subject to the EMC Directive in the European
Union. The EN61326 standard prescribes both emission and immunity
requirements for laboratory, measurement, and control equipment. This unit

1. OV-1000 Overview
The OV-1000 is an optical time domain reflectometer (OTDR) with integrated color
touchscreen and interchangeable modules for both single- and multi-mode fiber systems. It
also can include a VFL for additional continuity testing and a power meter for end-to-end
system attenuation testing. Also, The OV-1000 allows for automatic (auto mode), manual
(advanced mode), and reference (template) testing. The OV-1000 is battery operated or can
be plugged into an AC/DC converter (24V, 4A output).

2. Getting Started
2a. Inserting and Removing Test Modules
To insert a module into or remove a module from your unit:
1. Power off your unit.
2. To take a module out of the OV-1000, loosen the retaining screw on the
bottom of the unit using a coin (in a counter-clockwise direction) until the
module pops out and pull the module out. It is not necessary to remove the
screw to remove the module.
3. To put a module into the OV-1000, make sure the connector pins are at the
back and on the same side as the retaining screw. Look into the OV-1000, and
make sure you can see the screw to align it with the connector pins. On some
of the modules, there is a message that states: “This end towards back”.
Ignore the message because it is meant for module installation in an
OPTIVISOR 400 not the OV-1000. Once the pins are aligned, slide the module
in gently. Once the module slides as far as it can go, put pressure on the
module and tighten the retaining screw (turn in a clockwise direction) until the
module is flush with the unit. Do not use a screwdriver because you may over
tighten the screw and break the module (the pins may break).
4. When you turn on the unit, the startup sequence will automatically detect the
newly installed module. Also, if the module port is empty, please make sure it
has a blank port cover for protection.
2b. Turning the OV-1000 On or Off or going into “sleep” mode.
IMPORTANT
•The OV-1000 has both a sleep and off mode. In sleep mode (1 beep)
the unit is still consuming battery power.

1. To turn the unit on hold down the green button on the front panel for one or
two seconds. The startup screen briefly appears and the unit starts.
2. To turn the unit off press and hold the green button until the unit beeps twice,
and the unit will then shut itself down.
3. To put the unit into sleep mode press and hold the green button until the unit
beeps once, and the unit will go into sleep mode. To “wake up” the unit, touch
the green power button, and it should take about 4 seconds for the unit to load
up. This power mode can be used throughout the day, but should be fully
powered down at the end of the day.
2c. To start/exit a Module or the VFL/Power Meter or Probe Application
Once the startup screen is loaded, you should see a list of your modules on the left
and a main menu on the right. If you have more than one module, both modules will
be listed. To start a module select the one you would like to use by touching the
screen with your finger/stylus or by touching the button/hot key on the front panel of
the unit (corresponds to the slot). Under the module list, a list of applications
associated with the module should appear. Select the application you would like to
use then touch the start button on screen.
To start a VFL/Power Meter or Connector Probe application, look under the main
menu list and select the application you would like to use. Data storage is located
under the File Manager tab. The Setup tab is used to calibrate the stylus and
customize the system settings. See screenshot below.
Please note that each application is started in a new window. You must exit an
application to get back to the main menu. To exit any application, look for a red X at
the bottom right hand corner of the screen and touch it. Touching the X will close the
application and return you to the startup menu.

2d. Installing the Universal Interface (UI) adapter
1. To install a UI connector adapter onto the UI baseplate begin by holding the UI
connector adapter by the base and not the cap. The cap will break off if you
twist the adapter by the cap.
2. Close the dust cap in order to hold the connector adapter more firmly.
3. Align keys and insert the connector adapter into the base plate.
4. While pushing firmly, turn the connector adapter clockwise on the base plate to
lock it in place. To remove turn counterclockwise.
2e. Environmental Settings for the OV-1000
To setup your OV-1000 press the Setup button in the main menu on the start-up
screen. There are several things you can setup, but we are only going to point out a
few important things in the screenshot below.
Figure 3. Auto Mode – OTDR tab
1. Date/Time icon. Select icon to set date and time for unit.
2. Application startup icon. Select icon to setup modules to load on startup.
3. Volume & Sounds icon. Select icon to set volume and sound types.
4. Stylus icon. Select icon to calibrate stylus.

3. Installing Computer Software
You can install OTSView on a computer for data post-processing. Use the
CD-ROM that came with your OV-1000 and follow the instructions.
To install OTSView on a computer:
Insert the installation CD in the CD-ROM drive. The CD should autoload to a menu
screen, if not load the CD by clicking on my computer and selecting the CD-ROM/DVD
drive. At the menu screen select the link to the RELEASE NOTE. Once the RELEASE
NOTE has launched please print the instructions and follow each step. Failure to
follow these instructions will result in lack of communication between the
device and computer.
Figure 4. Auto Mode – OTDR tab
1. Release note link. Click on the link to open the release notes. Again please print
the release note and follow the directions to avoid any communication issues.
2. Start Installation link. Clicking on this link will start the process of installing the
required software on your computer. Please note that it will not install the trace
viewing software. That software is in the Viewers and Utilities links.
3. Viewers and Utilities link. Click on this link to install the trace viewing software
and other programs such as Adobe Acrobat.
IMPORTANT
•Plugging the unit into the computer without installing the software first
will result in driver errors.

4. Testing with the OTDR
4a. General testing procedure
To test in any mode, simply attach the fiber to the correct port. Note that some
modules can test both MM and SM fiber. Make sure that you connect the fiber to the
correct port which is labeled on the module. To start the test you need to select the
green Start button. The parameters you set vary from mode to mode and will be
discussed in the following sections.
4b. Setting up your OTDR
The following screenshots were taken from the Advanced Mode Testing module. Also,
the create ref/template setup tab in Template Mode is not shown. Please refer to the
main reference manual to see that tab. To get to the OTDR setup, press the OTDR
Setup button in the main menu on the right side of the screen(see Fig.9,button 9).
The setup tabs will load up and should look like the following.
Figure 5. OTDR setup – General tab
1. General Setup tab- Select this tab to access the general setup functions.
2-4. Display settings- Select whether or not you want a grid, the file name, or the
zoom window to appear on the trace.
5. Distance units settings- Select what units you would like to work in.
6. Automatic zoom button- Select this option if you want the OTDR to automatically
zoom in on a defined span after each trace is shot.
7. Touchscreen keyboard setting- Press this button if you want to turn on/off the
touchscreen keyboard.
8. Exit OTDR Setup button- press this button to exit setup and save settings
9. Close module button- press this button to close module, not the setup window.

reflectance, and end of fiber threshold, or choose the default settings by
hitting the default button. For example, if the splice threshold were set to
0.02dB, then a step of 0.01dB would not be detected, but a step of 0.02dB or
greater would be.
6. Span start setting- Set the system start by event number from the beginning or
by distance from the beginning. This is useful when you want to eliminate the
launch cable in your system calculations.
