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.
14 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.
(/MNT option is required.)
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, 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.

*1 The dB value is the maximum dynamic range of OTDRs for each target area
*2 A built-in cut filter to isolate from communication wavelengths included
The AQ7282A is ideal for measurement of less than 70 km networks, while the AQ7283A is the best choice for networks longer than 70 km with splitters.
The AQ7284A and AQ7285A are high dynamic range models designed for measurement of networks longer than 100 km.
Trace examples with pulse width of 1 μs
These OTDRs have a port for a maintenance wavelengths of 1625 nm or 1650 nm, which does not affect communication wavelengths, and a built-in cut filter to prevent interference with live communications traffic wavelengths.
The AQ7283E guarantees wavelength accuracy of 1625 nm±10 nm to enable maintenance of 10GE-PON, and the AQ7283F guarantees a maximum output power of +15 dBm or less and allows maintenance measurements on paths where output power is limited.
Trace examples of live communications lines
These OTDRs measures at more than three wavelengths without switching optical connector. The AQ7283H and AQ7284H detect macro-bending where the loss is larger at longer wavelengths and are useful for testing CWDM transmission paths using a wavelength of 1260-1625 nm.
The AQ7282G and AQ7283K are suitable for installation checks of FTTH networks that requires measurements at 1490 nm.
Trace examples with macro bending
The AQ7282M is useful for short-distance measurements where many multimode fibers exist, such as structured cabling in factories and data center networks.
As the optional stabilized light source has a guaranteed stability of ±0.15 dB at both 850 nm and 1300 nm wavelengths, it can be combined with the power meter module to measure optical loss.
These models guarantee a center wavelength of ±15 nm at all wavelengths, which meets the stringent light source requirements for optical fiber and cable manufacturing. Optionally, a center wavelength of ±10 nm (compliant with IEC 60793-1-40) can be specified. In addition, this model guarantees measurement accuracy and reproducibility for research and manufacturing applications and enables stable inspection measurements.
This is a license product for adding applicable optional features on to AQ7280 series on your own.
It is necessary to update main unit firmware in advance to R1.07 or later and above in order to apply this license.
