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.
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:
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.
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!
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!

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.
Remote control. Remote data transfer.
Control the OTDR remotely using WindowsTM operating system devices via wireless router connection technology.
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.
Hunt down your breakpoint precisely and promptly.
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.
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.
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.
Using the AQ7280's Wireless Connectivity, the PDF reports can be transferred through the internet for immediate reporting.
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.
Thanks to the OTDR's advanced analysis function and macro bend characteristics, users can immediately identify and locate macro 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!
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.
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.
A wide selection of diaplay languages assists users in operating the AQ7280 in their native language. Available languages influde, but not limited to: Chinese, Czech, Dutch, English, Finnish, French, German, Italian, Norwegian, Polish, Portuguese, Spanish, Swedish, and Turkish.

|Quality inspection of low-OH optical fibers/cables
Low-OH single mode fibers*¹ are available for CWDM applications. They are tested at 1383 nm in each process of production.
Having four wavelengths in one port, the AQ7283J can measure at four wavelengths without switching the optical connector by just pressing one single button. It can be controlled remotely via a USB or Ethernet interface.*²

|Loss test of existing networks before introducing CWDM transmission system
When the introduction of the CWDM transmission system to existing optical fiber networks is considered, the optical loss of the network at 1383 nm needs to be measured because a traditional optical fiber may be used.
Thanks to its portable design, the AQ7283J OTDR unit can measure the loss at 1383 nm on-site where optical fibers are installed.
|Measurement of live communications lines
The built in communications wavelength cut filter in a dedicated 1625 nm port enables testing of fiber where live communications traffic wavelengths (1310, 1490, 1550 nm) exist.
|OTDR waveforms of live communications lines|
|Macro bending measurement
The optical transmission loss of optical fibers at long wavelengths like 1625 nm increases at the point where the macro-bending occurs. By comparing OTDR waveforms measured in each wavelength, the macro bending can be detected.
