Product Description

The Factory Original Japan Yokogawa Reflectometer AQ7280 OTDR

The Factory Original Japan Yokogawa Reflectometer AQ7280 OTDR is a high-performance optical time-domain reflectometer engineered to deliver precision, durability, and user-friendly operation for fiber optic network testing and maintenance. Designed for professionals in telecommunications, data centers, and industrial sectors, the AQ7280 combines advanced measurement capabilities with robust portability, ensuring reliable analysis of fiber optic cables from installation to troubleshooting. As part of Yokogawa's trusted AQ7000 series, this OTDR sets a benchmark for accuracy and versatility in modern fiber optic testing.

The AQ7280 excels in measuring optical fiber characteristics, including attenuation, splice loss, connector reflections, and fault locations. It supports multiple wavelength options (1310 nm, 1550 nm, and 1625 nm) to accommodate single-mode and multimode fibers, enabling comprehensive diagnostics for diverse applications. With a dynamic range up to 40 dB and a measurement capability of up to 300 km, it ensures precise detection of events even in long-haul networks. Its short event dead zone (≤1.2 m) and attenuation dead zone (≤5 m) allow users to identify closely spaced faults or connectors, critical for dense network environments like data centers and FTTx deployments.

Built for field efficiency, the AQ7280 features a 5.7-inch color touchscreen interface with intuitive software, simplifying setup and real-time trace analysis. Its lithium-ion battery provides up to 10 hours of continuous operation, minimizing downtime during extended fieldwork. The device supports seamless data management via internal storage for up to 10,000 traces, USB connectivity, and optional Wi-Fi/Bluetooth integration for quick report generation and cloud synchronization. Yokogawa's FiberTest Suite software enhances productivity by automating trace analysis, generating professional reports (PDF/CSV), and offering cloud-based collaboration tools.

Engineered to withstand harsh environments, the AQ7280 meets IP52 protection standards, resisting dust and splashes while maintaining reliability in temperatures ranging from -10°C to +50°C. It is certified to meet global industry standards, including CE, FCC, and Telcordia GR-196-CORE, ensuring compliance with telecom regulations.
