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.
15 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 (DI-1000-B2/ DI-2000-B2 (Lightel)) 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.

AQ3550 Optical Switch Box

The AQ3550 12-ch optical switch box for SMF works in conjunction with an OTDR.
Control and power supply are performed from the OTDR main frame, while the optical switch box enables continuous measurement of all or a selection of the 12 channels.
It is useful when measuring multiple fibers, such as optical fiber tape, under the same conditions.
*AQ3550 is not available with AQ7282M

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.
