Product Description

Product Description

The Factory Original Japan Yokogawa Reflectometer AQ7280 OTDR

The Yokogawa AQ7280 OTDR (Optical Time-Domain Reflectometer) is a high-performance, factory-original test instrument designed to meet the evolving demands of fiber optic network installation, maintenance, and troubleshooting. Developed by Yokogawa, a global leader in precision measurement technology, this advanced OTDR delivers exceptional accuracy, robustness, and ease of use for field technicians and engineers working in telecommunications, data centers, and industrial fiber optic systems. With its cutting-edge optical analysis capabilities and user-friendly design, the AQ7280 ensures reliable characterization of fiber links, enabling efficient deployment and long-term network reliability.

Advanced Measurement Capabilities for Comprehensive Analysis
At the core of the AQ7280 is its ability to perform detailed fiber optic diagnostics by analyzing backscattered light pulses. This enables precise measurement of attenuation, splice loss, connector reflections, and fault locations across single-mode and multimode fibers. The OTDR's high dynamic range (up to 40 dB) allows it to analyze long-haul networks, including metropolitan and access networks, with exceptional clarity. Its short dead zones (as low as 0.8 meters) ensure accurate detection of events close to connectors or patch panels, making it ideal for testing dense fiber infrastructures in data centers and premises.

The AQ7280 supports a wide range of wavelengths (e.g., 1310 nm, 1550 nm, and optional 1625 nm), enabling compliance with ITU-T and industry standards for fiber testing. Its automated measurement modes simplify operation by optimizing pulse width, averaging time, and range settings, ensuring fast and repeatable results even in complex environments. For advanced users, manual adjustments provide granular control over test parameters, enhancing flexibility for specialized applications.

Rugged Design for Field Reliability
Engineered for demanding field conditions, the AQ7280 features a durable, lightweight chassis with an IP65-rated enclosure, protecting against dust, moisture, and accidental spills. Its shock-resistant construction ensures durability during transport and use in harsh outdoor environments. 

Seamless Data Management and Connectivity
The AQ7280 prioritizes efficient data handling through its built-in storage for thousands of trace files and reports. Users can export results via USB, LAN, or WiFi to PCs, cloud platforms, or network management systems for further analysis. Yokogawa's FiberViewer software offers advanced trace visualization, automated pass/fail analysis, and customizable reporting, enhancing productivity for teams managing large-scale deployments.

For real-time collaboration, the OTDR supports remote access via LAN or WiFi, allowing supervisors to monitor measurements and troubleshoot issues from a central location. This feature is particularly valuable for global enterprises managing distributed networks.

Key Applications Across Industries
The AQ7280 is indispensable for a variety of scenarios:

Telecom Networks: Verifying fiber integrity in backbone, metro, and access networks.
Data Centers: Testing high-density fiber links to ensure low-loss connections.
Industrial Systems: Monitoring fiber health in oil & gas, power generation, and smart infrastructure projects.
Custody Transfer: Providing legally defensible test results for network certification.
Its versatility extends to bidirectional testing when paired with a remote partner OTDR, eliminating ghost events and improving accuracy in complex networks.

User-Centric Features for Efficiency
The AQ7280 streamlines workflows with intuitive one-button testing, automatic event analysis, and on-screen Pass/Fail indicators based on customizable thresholds. Its built-in visual fault locator (VFL) aids in identifying breaks or bends in fibers, while an optical power meter (OPM) measures live signal levels without additional tools.

Technicians benefit from context-sensitive help menus and on-device tutorials, reducing training time for new users. The OTDR's modular design allows easy upgrades, such as adding wavelength modules or extending memory capacity, future-proofing the investment.
