Eagle Eye

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.

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!

Modularity

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 Lightel^TM 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.)

Macro Bending Detector

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!

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.

Multi-Language Support

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.

AQ7283J

Applications

Traditional single-mode fibers (SMF) contain a large amount of water ions (OH). Since water ions (OH) absorb light at 1383 nm, the optical loss of single-mode fibers increases at 1383 nm, this characteristic is known as the water-peak. The AQ7283J was designed with the 1383 nm wavelength capability to specifically test the water-peak in SMF.

AQ7283E

Applications

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.
*Other OTDR units with 1625 nm: AQ7283H, AQ7283K, etc.

Additional Option License for AQ7280

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.  

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.

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.
