Description

The Yokogawa AQ7270 is a high-performance Optical Time Domain Reflectometer (OTDR) designed for precise fiber-optic network testing, installation, and maintenance. Engineered for use across a wide range of optical networks from FTTH (fiber-to-the-home) to metro and long-haul links it delivers fast, reliable measurements with an exceptionally short event dead zone of less than 0.8 m, enabling accurate detection of closely spaced reflective events on fiber lines.

Featuring a large, bright 8.4″ color LCD and a rugged yet compact body, the AQ7270 improves work efficiency by significantly reducing the time from power-on to measurement. Users can transmit and analyze test results via USB or Ethernet interfaces, and optional analysis software simplifies report generation on a PC. One-button and full auto modes streamline operation for technicians of all experience levels, while advanced functions like active line alarm, multi-wavelength measurement, and built-in utilities (optical monitor, light source, dummy fiber, and optional thermal printer) enhance versatility in diverse field environments.

With support for multiple wavelengths and high dynamic range performance, the Yokogawa AQ7270 enables both short-range event detection and long-distance fiber characterization with accurate loss and distance measurements. Its intuitive interface, rapid start-up, and robust functionality make it a powerful tool for fiber-optic infrastructure deployment, troubleshooting, and quality assurance tasks.
