Yokogawa AQ7280 Modular OTDR


New product

The AQ7280 is the most flexible OTDR in our lineup due to a modular platform to create a variety of systems from a basic unit to units with filtered ports to test live traffic networks in applications from long haul, to metro, core and FTTH.

More details



35+ years of OTDR expertise has enabled us to offer a unique multi-tasking feature that allows four distinct fibers to be tested simultaneously. Its intuitive icon-based touchscreen lets users perform measurements with ease, and the 15-hour battery life ensures uninterrupted usage in the field where the data can be conveniently transferred wirelessly.

The AQ7280 satisfies a broad range of test and measurement needs in analyzing optical networks from access to core.

The AQ7280 OTDR delivers:

  • Reliability: Robust design for operating under harsh field conditions. Proven operating system assuring stability, prompt response, and superior protection against software virus attacks.
  • Ease-Of-Use: Dual operation mode by multi-touch touchscreen and hard-key buttons. Fully automatic measurement and easy-to-read analysis reports through new software applications.
  • Speed: Lightning startup time. Multi-tasking operation to enhance productivity. Immediate reporting via wireless connectivity.


Enhancing productivity!

Managed by a highly efficient operating system, multiple functions can work simultaneously.
Now, users can perform OTDR measurements on a particular fiber core while simultaneously checking the power level and connector surface quality on others.

Dual-Operation Mode

Touch screen and hard-key buttons!

Tap, swipe, pinch, or press. Choose between the high resolution 8.4" multi-touch capacitive touchscreen or the robust hard-key buttons in any combination desired. OTDR operations have never been easier!

Lightning Startup Time

Under 10 seconds!

Thanks to the latest high speed hardware and a highly efficient operating system, the AQ7280 starts up from completely OFF to measurement-ready in seconds. It's always ready when you are!

Smart Mapper

Single button measurement. Comprehensive network characterization. Easy-to-read report.

Measurement acquisitions with multiple pulse widths and smart-algorithm enable users to detect and comprehensively characterize network events by pressing one single button. Simple, icon-based map view for easy interpretation of network events. Immediate PASS/FAIL judgment based on user-defined thresholds. Easily toggle trace view for manual supplementary analysis.
(/SMP option is required.)

Multi-Fiber Measurement

Database view. Organized. Quick preview of network characteristics.

OTDR-based application in a database view. Guides users in tracking multi fibers measurements in sequence. OTDR trace, power level and connector surface image of a particular fiber core are organized as one group. With PASS/FAIL judgment, fiber core performance is easily characterized.

Wireless Connectivity

Remote control. Remote data transfer.

Control the OTDR remotely using Windows operating system devices via wireless router connection technology. Transfer measurements results from the OTDR to Windows operating system devices via FreshAir technology. Send the results/reports by email/file transfer software for immediate reporting.

15 Hours Battery Operation

Just keeps going!

Imagine working an entire work shift at your remote work site without worrying about running out of battery power. The AQ7280's powerful Li-Ion battery will last for an amazing 15 hours under the Telcoria standard conditions and 10 hours even with the laser continuously turned on!


Full range of selections.

9 OTDR units ranging from single mode to multi mode, from low dynamic range to ultra-high dynamic range, and 2 wavelengths to 4 wavelengths. Selection of power sensor, light source, visible light source, and fiber inspection probe for instrument's customization based on users' needs.

Connector Quality Assurance

Zoomed in, checked out, all fixed up.

Using high-performance LightelTM fiber inspection probe, fiber connector surface is visualized for inspection of scratches and dirt. Reduces 90% of fiber cable problems.

Fiber Surface Test Function (/FST option is required.)

The fiber surface testing function will perform pass/fail judgment according to the threshold of dirt and scratches by automatically analyzing the image data of fiber surface received via the fiber inspection probe.

  • Pass/fail judgment standard can be set to IEC61300-3-35 compliant or customized settings.
  • In order to receive fiber surface data, you will need a fiber inspection probe (Lightel DI-1000-B2) which is compatible with the AQ7280 OTDR.

PDF Reporting

Using the AQ7280's Wireless Connectivity, the PDF reports can be transferred through the internet for immediate reporting.

  • Built-in post-proessing software for generating OTDR reports in PDF format
  • Flexible configuration of report template to meet users' report requirements

Intermittent Connection Monitoring

Under cold weather conditions, fiber network connectivity can be interrupted intermittently due to bending or losse connections. Identifying such intermittent interruption requires periodic monitoring and advanced analysis algorithm.

The OTDR Schedule Measurement function is useful when monitoring a particular fiber core based on user-defined measurement period and interval. Measurement results are compared with a reference trace and analyzed for any discrepancies. Based on the user-defined loss threshold, discrepency at a particular distance is identified and the occurance time is recorded.
(/MNT option is required.)

Fault Locator

The Fault Locator is an OTDR-based application for simply identifying the fiber break location.

Adaptive, smart-algorithm based on selected network architectures, such as point-to-point or PON network topology.Simple view of distance information for easy interpretation. Easily toggle trace view for additional detail analysis.

PON Optimized

Excellent hardware performance and advanced analysis algorithm, enables the AQ7280* to accurately characterize Passive Optical Network (PON) through high-port-count splitters (up to 1 × 128).

PON mode assists beginner/expert users in simply configuring OTDR measurement settings based on PON topology information for optimal results. Short event dead zone and high sampling resolution enable users to detect near-end location of connectors that are as close as 0.5 meters (<20 inches).

With the built-in optical cut filter and dedicated measurement port, the AQ7283F module is capable to measure live PON for maintenance purpose.

*Available in selected AQ7280 modules.
