The AQ7270 OTDR maximizes the total working time during on-site tests as the time to power up the device, make measurements, and analyze and store the measurement results are significantly reduced. The measurement results can easily be transmitted to computers using the USB interface or the Ethernet. The optional analysis software helps with preparation of computer-generated reports.

Meets fiber testing from FTTH to Metro networks!

From 1- to -4 wavelength models
The AQ7270 comes in eleven models combining different measurement wavelengths and dynamic ranges. Supported wavelengths: 1310, 1490, 1550, 1625, 1650 nm (single mode), 850 and 1300 nm (multi mode).
 

World's Shortest Dead Zone <0.8m (2.7 ft)
Accompanying the rapid proliferation of FTTH is a growing need for detection of reflective events arising from short-distance mechanical connections.

The AQ7270's event dead zone is the shortest in the world, enabling detection of closely spaced events.

High Dynamic Range up to 40dB
The high dynamic range of the AQ7270 enables accurate measurements of optical fibers in short periods of time.

This makes it a powerful tool for evaluation of metro networks with relative distances in excess of 100km, or FTTH (PON) and other short optical fiber networks with large insertion loss operating from optical couplers.
 

Less than 10 seconds Power-up Time
It's ready when you're ready!
Now measurements can be started quickly upon arrival at the site. Ten 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 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 demand for portable and reliable test equipment to aid the installation and maintenance of these networks.

The Yokogawa AQ7270 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), while adding a Detail Mode for trained technicians with functions for setting measurement conditions and performing manual measurements.
 

Multi Wavelength Measurement is a mode in which multiple specified wavelengths are measured automatically, in order. You can also specify to perform analysis or file saving as needed for each measurement.

Measurement with Auto Wavelength Switching - Multi Wavelength Mode -
Prepare multiple wavelengths to measure, then press a button.

Macro's Measurement with Predefined Procedures - One Button Mode -
Simply choose previously set measurement procedures, then press a button.

You can execute up to five saved measurement procedures in order. A batch of measurement procedures can be run directly from the main menu. Measurement and analysis conditions can be read from a file making it easy to set up the measurement procedures.

Easy Operation with the Assistance Function!
Assistance Setting Up Measurements - Measurement Wizard -
 

Displays detailed explanations of parameters in the measurement conditions setting menu, and gives guidelines for setting methods. This function assists unskilled users.

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 alarm monitors the fiber's optical power level and displays 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.

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.

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
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, a waveform can be loaded from a file to be used as the reference waveform.

With the new SETUP button on the front panel, it is easy to move to the measurement condition setting menu.
