▼Further enhanced waveform measurement function of the AQ7270 OTDR.
●Improved dynamic range, demonstrating its power in measuring transmission lines with large losses such as mid-span fibers and splitters
●Improved S/N ratio allows clear observation of waveforms across splitters
●Power-saving design doubles the battery life compared to the AQ7270!!
●Over 1,000 waveforms can be saved in the internal memory, and even more waveforms can be saved using an external USB flash drive
●Large semi-translucent color LCD (8.4-inch) that is easy to see even under direct sunlight outdoors
【Various OTDR Analysis Functions】
Multi-wavelength analysis, dual-wavelength combination, differential waveform analysis, and span analysis are available
【Cutover Work Support Function】
Manages measurements before and after construction. Helps reduce communication service downtime
【Multi-core Fiber Measurement Function】
Organizes the file names of each core into a table, significantly reducing work time
【Scheduling Function】
The OTDR automatically measures at the set intervals. No need for the operator to stay on-site even during long-term monitoring
【Macro-bending Detection Function】
Automatically detects bending-induced attenuation during multi-wavelength measurements
▼Excellent cost performance,
Easy operation further increases work efficiency
FTTH to Metro, Core, meeting a wide range of measurement requirements
●0.8m event dead zone
●High dynamic range of up to 45dB
●Fast startup in under 10 seconds
▼Easy to use even for first-time users
Operating modes can be selected according to the operator's skill level
[Simple (Full Auto) Mode] [Measurement Wizard Mode] [Detailed Mode]
●Continuous measurement by switching wavelengths - Multi-wavelength measurement
●Measure overlaid with a reference waveform - Waveform freeze function
●USB function
●Multi-core fiber measurement function
