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!


The worldwide spread of broadband services has stimulated the installation of optical fiber in metro and access networks, which in turn has increased the demand for portable and reliable test equipment to aid the installation and maintenance of these networks.
Our new OTDR has been developed to address these challenges with particular aims of improving operability to boost work efficiency and cost-effectiveness.
The AQ7270 carries forward the basic operation of its predecessors (the AQ7250 and AQ7260 OTDR), while adding a Detail mode for trained technicians with functions for setting of measurement conditions and performing manual measurements.

Active Line Alarm

Never disturb communication lines
There may be concern that technicians inputting the OTDR measurement signal into the communication line could cause communication errors.
The live line alarm monitors the fiber’s optical power level and diplays an alarm message if it detects optical power at or higher than a specified threshold level, in order to warn the technician not to mistakenly feed the signal into the communication line.

Plug Check Function

Never spoil measurements with poor connections or dirty plugs

The plug check function monitors the condition of the OTDR's optical input/output 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, and for helping technicians to remember to connect the fiber under test.

Fault Event Display Function

Detecting Abnormal Events


J013 Fault Event

The fault event display function detects abnormal connection or reflection points and displays them. Of the events detected by the event detection function, abnormal events that cross a specified threshold value are highlighted in the event table and waveform display.

Trace Fix Function

Measurement with Comparison to a Reference Trace

You can freeze the display of one trace and overlap it with real time or averaged waveforms for comparison.
This is useful to create 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 to be used as the reference waveform.

Trace Analysis Functions

Multi Trace Analysis
For Evaluation of Multicore Fiber
Up to four traces can be overlaid on the display for analysis and comparison.

This is useful for evaluating connection point locations and loss after installing multicore fiber.

Multi Trace


2 Way Trace Analysis

For Accurate Splice Loss Measurement
by Bi-directional Testing
Merges the two traces measured from both directions and finds the correct splice loss.

Connection point loss in lines where optical fibers of differing backscatter coefficients are connected can differ depending on the direction. In such cases, you can accurately determine the loss by measuring in both directions and taking an average.



2way


Differential Trace Analysis

For Evaluation of Aged Deterioration
Displays the difference between two specified traces.

Makes it simple to check aged deterioration of fibers or connection points, or fluctuation in loss between fibers, and other phenomena.

Differential


Section Analysis

For Evaluation of Total Return Loss

Finds the total return loss in specific portions of the fiber.

This type of evaluation is often requested because the multiple reflections from optical fiber networks can affect signal light from transmitters (cable TV etc.).

Smart File Function

Smartfile

Because the AQ7270 makes it easy to differentiate between measured optical fibers-even complex ones-you can add arbitrary information to file names such as measured wavelength, ID number, tape number, or comments. You can also have the ID number or tape number automatically updated and saved after each measurement.
Trace data can be saved in SOR and CSV format. Also, you can save screens as BMP, JPG, or PNG files. TRB or TRD files saved on Yokogawa's previous AQ7250 and AQ7260 models can also be loaded.


Language Selection

In addition to English (standard), you can select a display language of French, German, Chinese, Korean, Russian, and others.

DummyFiber

Fibers in offices frequently involve short distances between connectors. By using the dummy fiber, you can check whether there is any abnormal near-end connection loss. Also, by measuring the connection loss at the near-end connector, you can determine the total fiber loss including that of the connector.

Optical Power Monitor (/PM Option)

Using the power monitor (factory option), you can check optical power for link loss testing or when troubleshooting. Useful for checking the optical power at the ONU's receiver in FTTH. When combined with a stabilized light source, it can also be used as an optical fiber identifier.
