OTDR Yokogawa AQ-7275
The AQ7275 is one of the best selling OTDRs
in the world. Model lineup has been expanded to a total of 9 models to
choose from with a dynamic range of up to 45dB . Wavelength capability
spans from 850nm (MMF) to 1650nm (SMF). An impressive 0.8m event dead
zone makes this model an excellent choice for FTTH and metro, core
networks.
Enhancements include a PON option allowing accurate event
analysis after a 1x32 splitter with significantly reduced undershoot
effects. Also unique to the industry is a built-in section of launch
fiber to eliminate the need for a separate launch box.
Latest standard features includes the convenient capability to
display a fiber connector inspection probe using one of the unit's
standard USB I/O ports.

multimode and single mode fiber. Dynamic range is specified when
measuring 50GI fiber. |
Meets a broad range of measurement needs from FTTH to Metro, Core network.
Event Dead Zone 0.8 m
| Accompanying the rapid proliferation of
FTTH is a growing need for detection of reflective events arising from
short distance mechanical connections. The AQ7275’s short event dead
zone enables detection of closely spaced events in cables installed in
offices and customer premises. |
 |
High Dynamic Range up to 43 dB (45dB typical)
| The new High Dynamic range model (735034) can achieve the dynamic
range of 40 dB. This high dynamic range is effective in measuring a
transmission line consisting of long fiber cables and a splitter with a
large loss. |
 |
Quick Startup within 10 Seconds
Now measurements can be started quickly upon arrival at the site. 10
seconds to power-up from completely OFF to fully ON! With such a fast
power-up time, battery life can be extended by turning the power off
while not in use at the job site without any concern about the power-up
time when the next job is ready. It’s ready when you’re ready!
Stabilized Light Source
| This light source option can be used for
measuring losses. It can also be used for optical fiber identification,
because it is capable of outputting not only continuous wave (CW) light
but also a 270-Hz modulated light.
* The stabilized light source option cannot be used for the 735041 (MMF). |
 |
Visible Light Source
This option can be used for identifying the multicore fiber cable and
visually checking for a failure. The adopting the connector connection
method enables the visible light to reach greater distances with less
light leakage.
* The visible light source option cannot be used for the 735036, 735037, and 735041.
Built-in Dummy Fiber
You can use the dummy fiber to effectively detect abnormal near-end connection loss.
* The dummy fiber option cannot be used for the 735041.
* The built-in dummy fiber is not attachable and removable.
Optical Power Monitor
This is useful for simply checking optical power when performing link loss testing or troubleshooting.
* The optical power monitor option cannot be used for the 735031 and 735041 (MMF). |

Angled-PC Connector
You can connect an optical fiber with an angled-PC connector directly to
the OTDR. The angled PC is often used for CATV networks to reduce the
influence of reflection.
External Large Capacity Battery
Model 739881
External battery attached to the the OTDR extends the battery
operation time up to 18 hours, which is three times the standard battery
operation.
Printer/LAN
| Measured results can be printed on site.
It makes it easy to attach the printed sheet to your report. Remote
control and FTP (file transfer) via LAN is also possible. |
 |
Easy to Operate for Beginners and Experts
Setup mode can be selected according
 |
 |
 |
| Simply select the measured wavelength and
the AQ7275 takes care of the rest by automatically setting the optimal
measurement conditions and by performing measurement and event analysis,
and fully automated data saving. |
Display the guidelines for the setup items from the Setup menu. Follow the step-bystep instructions to complete the setup. |
This mode allows you to set all the
detailed settings, not only the measurement and analysis settings but
also the screen display and system settings. |

Macro's with Predefined Procedures
One-button MeasurementSimply select previously set measurement procedures and then push a button.
You can execute up to 5 previously set and saved measurement procedures automatically.
Measurement
and analysis conditions can be loaded from a file, making it easy to
set up measurement procedures you executed previously.

Measured
waveforms for multiple wavelengths are displayed on a single screen, so
it is easy to compare the waveforms. The measured data is saved to
memory.
Useful Support Functions
Checking the Connection with the OTDR
- Plug Check Function
You can detect poor connections and dirty plugs
The
plug check function monitors the condition of the optical connectors
and displays an alarm if the connection is not properly made. This
function is useful for checking for damage, dirt, or other problems with
optical plugs at the OTDR or on the fiber under test. It is also useful
for helping technicians to remember to connect the fiber under test.
Detecting Fault Events
- Fault Event Display Function
The fault
event display function detects and displays abnormal connection or
reflection points. Of the events detected by this function, abnormal
events that cross a specified threshold value are highlighted in the
event table and waveform display.
Measurement with Comparison to Reference Waveform
- Trace Fix Function
| This function enables you to freeze the
display of one waveform and overlap it on real-time or averaged
waveforms. This is useful for creating a template when installing
multicore fiber, or for checking aged deterioration during maintenance
on existing fiber networks. In addition to the last measured waveform, a
waveform can be loaded from a file for use as a reference waveform. |
 |
USB Function
The AQ7275 has two USB 1.1 compliant connector ports as standard (Type A and Type B).
Type A port is for USB memory and USB hard disk drivefor storage.
Type
B port is for connecting external PC. AQ7275 can be remotely controlled
from external PC, and an internal memory of AQ7275 can be accessed from
external PC directly. |
 |
Multi Fiber Measurement Function
The Multi fiber measurement function automatically performs
measurements and data-filing according to a pre-established file name
table. At worksite, you can execute it by simply selecting a fiber
number in the table.
The saved waveform can be easily shown in the preview window by selecting the core number in the table.
The OTDR Project File Editor included in AQ7932 Emulation Software greatly saves time to create file name table.
Multi Core Trace Comparison Function
Communication services must be interrupted when existing fiber optic
cables are rerouted due to construction work of roads and buildings.
This function minimizes the duration of the interruption by improving
the efficiency of the rerouting work.
A waveform is measured before
and after the work and compared against one another to determine a
pass/fail condition using a user defined threshold criteria.
This
function also enables the management of cores of a multicore fiber optic
cable by number and color. This prevents the user from measuring a
wrong core.
Numbers for measured cores are marked with check marks.
This prevents the same core from being measured multiple times plus
ensures no cores are overlooked.
Macro Bending Function
If there is a bend in the optical fiber, the longwavelength loss is higher at the location of the bend.
This function uses this characteristic to locate macro bends by measuring the same line at multiple wavelengths.
Scheduling Function
Fiber optic networks are known to be subject to seasonal failures such as one caused by freezing. Such
failures
are restored automatically after several minutes to several hours. Thus
the failure cannot be located due to the temporary nature of the fault.
The scheduling function performs measurements automatically in the specified period and saves the
measurement data automatically to an external USB flash drive. The AQ7932 Emulation Software on a PC is
used
to call up the data before and after the fault event from a large
amount of data automatically saved to the USB flash drive, and analyze
the chronological changes in the waveform to locate the failure.
In
addition, the remote control software provides support for measurements
using the scheduling function, by providing a function to transfer the
data stored in the USB flash drive to the PC via a network cable; a tool
that
detects a data file containing a change exceeding the threshold from a
large number of data files; and a tool that batch calculates losses
between two points.
