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.

The Trace Info tab in advanced mode is the same as in auto mode, except for the
fiber settings button. Here you can manual change the settings of the fiber (ex. IOR,
back scatter, helix factor). If you do this then you will need to re-analyze the trace.
The source tab in Advanced Mode testing is the same as in auto-mode testing.
4e. Template Mode Testing
Template Mode Testing allows the user to shoot trace files using a reference or
“standard” trace for comparison. The user creates a sample trace as a reference and
then compares that to all the following traces. This insures that all traces have the
same number of events regardless in the event table. This avoids the issue where a
known splice or connector pair is skipped due to it falling below the detection
thresholds. Please refer to the full user manual for additional information.
