A high-dynamic model used for core and metro network construction and maintenance!!
▼Enhanced waveform measurement functions compared to the AQ7270 OTDR.
● Improved dynamic range, effective for measurements on long-distance fibers or transmission lines with high losses such as splitters.
● Improved S/N ratio allows for clear observation of waveforms even past splitters.
● Equipped with stabilized light source and optical power monitor functions.
● Energy-saving design doubles the battery life compared to the AQ7270!!
● Internal memory stores over 1,000 waveforms; additional capacity via external USB memory.
● Large (8.4-inch) semi-transmissive color LCD, easy to read even under direct outdoor sunlight.
【Versatile OTDR Analysis Functions】
Multi-wavelength analysis, dual-wavelength synthesis, differential waveform analysis, and section analysis.
【Relocation Construction Support Function】
Manages pre- and post-construction measurements. Helps shorten communication service downtime.
【Multi-core Fiber Measurement Function】
Tabulates filenames for each core, significantly reducing work time.
【Schedule Function】
Automates OTDR measurements at set intervals. No constant operator presence required for long-term observations.
【Macro-bending Detection Function】
Automatically detects attenuation due to bending during multi-wavelength measurements.
▼Excellent cost-performance,
Easy operation to further increase efficiency
Meets a wide range of measurement requirements from FTTH to metro and core networks.
● 0.8m event dead zone
● Up to 45dB high dynamic range
● Fast startup in under 10 seconds
▼User-friendly interface for beginners
Selectable mode settings based on operator skill level
＜Simplified (Full-Auto) Mode＞ ＜Measurement Wizard Mode＞ ＜Advanced Mode＞
● Sequential measurement by switching wavelengths - Multi-wavelength measurement
● Measurement overlaid with a reference waveform - Waveform fixing function
● USB functions
● Multi-core fiber measurement function
Stabilized Light Source
Can be used as a light source for loss measurements. It outputs not only continuous light (CW) but also 270Hz modulated light, making it useful as a light source for fiber identification.
*Does not support multi-mode fiber.
Built-in Dummy Fiber
Includes a built-in dummy fiber effective for detecting near-end abnormal losses.
*The built-in dummy fiber is not removable.
Optical Power Monitor
Convenient for quick checks of optical power during service activation or troubleshooting.
*Does not support multi-mode fiber.
