▼Further improved the waveform measurement function of the AQ7270 OTDR.
● Improved dynamic range, demonstrating its power in measuring transmission lines with large losses such as mid-range fibers and splitters
●S/N improvement allows clear observation of waveforms across splitters
●Equipped with a stabilized light source function and optical power meter function
●Battery life is twice that of the AQ7270 thanks to the power-saving design!!
●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-transparent color LCD (8.4-inch) that is easy to see even under direct sunlight outdoors
<Various OTDR Analysis Functions>
Multi-wavelength analysis, 2-wavelength composite, differential waveform analysis, and section analysis are possible
<Support Function for Relocation Work>
Manages measurements before and after construction. Contributes to shortening communication service downtime
<Multi-core Fiber Measurement Function>
Tabulates the file names of each core, significantly reducing work time
<Schedule Function>
The OTDR automatically measures at the set interval. 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 measurement
▼Excellent cost performance,
Easy operation further increases work efficiency
Meets a wide range of measurement requirements from FTTH to metro and core networks
●0.8m event dead zone
●Fast startup in under 10 seconds
▼Easy to use even for beginners
Operating modes can be selected according to the operator's skill level
Simple (Full Auto) Mode> Detailed Mode
●Continuous measurement by switching wavelengths - Multi-wavelength measurement
●Measure overlaid with the reference waveform - Waveform freeze function
●USB function
●Multi-core fiber measurement function
Stabilized Light Source
Can be used as a light source for loss measurement. It can also output 270Hz modulated light as well as continuous wave (CW), so it can be used as a light source for core comparison.
*Does not support multimode fiber.
Built-in Dummy Fiber
Can be equipped with a dummy fiber that is effective in detecting near-end abnormal loss.
*The built-in dummy fiber cannot be removed or replaced.
Optical Power Meter
Convenient for simple optical power checks during commissioning tests or when a failure occurs.
*Does not support multimode fiber.

| ■Condition |
■Tested and confirmed to be in working order!!
To deliver a good product to our customers, we have performed the following cleaning before sale.
Cleaning areas
・Exterior cleaning
・Interior cleaning
However, as it is a used product, there are small scratches from use.
・Self-test and self-diagnosis tests were successful. It can be used without problems.
The text on the operation buttons is currently more faded than it appears in the photos.
We are offering it for 10,000 yen cheaper than usual, so we look forward to orders from understanding customers
