Selection Guide


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.

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 WindowsTM operating system devices via wireless router connection technology.Yokogawa
Transfer measurements results from the OTDR to WindowsTM operating system devices via FreshAirTM technology.
Send the results/reports by email/file transfer software for immediate reporting.

Eagle Eye

Hunt down your breakpoint precisely and promptly.Yokogawa
Enabling the highest possible sampling resolution in a long distance measurement range, distance offset error is reduced.
With a relatively small distance offset error, users are able to pinpoint the actual break location in high distance accuracy.
Faster location identification, faster repair time.

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. YokogawaThe 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 Yokogawawavelengths 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.Yokogawa
Reduces 90% of fiber cable problems.

PDF ReportingYokogawa

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. Yokogawa

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. 

Macro Bending Detector

Thanks to the OTDR's advanced analysis function and macro bend characteristics, users can immediately identify and locate macroYokogawa bend events along a fiber network. 
Multi-wavelength traces are acquired on the same fiber, then is compared and analyzed automatically in a single-button operation. 
When the loss difference of a same location event at different wavelengths is more than the user's defined threshold, the macro bend is detected!

Fault Locator

The Fault Locator is an OTDR-based application for simply identifying the fiber break location. Yokogawa
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 enable the AQ7280 to accurately characterize Passive Optical Network (PON) through high-port-count splitters (up to 1 x 128).
PON mode assists beginner/expert users in simple 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 (With the built-in optical cut filter and dedicated measurement port, the AQ7283F module is capable to measure live PON for maintenance purposes. 


Optical Power Meter & Checker

Measures and displays optical power of a light source as an absolute/relative value for testing transmitter/network performance. Measurement results can be saved for reference purposes. 
Invaluable test instrument during installation and maintenance.
Calibrated and selectable wavelength setting. Single-mode and Multi-mode measurement ready. Continuous wave and modulated wave detection capability.
Two selections of optical power sensors are available- optical power meter and optical power checker, different on the specs and functions. 

Optical Light Source

Outputs a stable, continuous wave of light for measuring end-to-end attenuation accurately when paired with Optical Power Sensor. Modulated light function at 270 Hz/1 kHz/2 kHz is also available for fiber identification or continuity check purpose on a live fiber network. 

Visible Light Source

Visible, continuous/modulated red light laser. Invaluable test instrument for checking the continuity of pathcords, launch fibers, or short fiber trunks. Breaks and bendings in fiber can be identified visually as the visible light exits the fiber on such fault events.
