A high-dynamic model used for construction and maintenance of core and metro networks!!

▼Further improved waveform measurement function of the AQ7270OTDR.

● 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
● Equipped with a stabilized light source function and optical power monitor function
● Battery life is twice that of the AQ7270 due to a power-saving design!!
● Can store over 1000 waveforms in internal memory, and even more waveforms can be stored using an external USB flash drive
● Large transreflective 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 Pole Relocation Construction]　
Manages measurements before and after construction. Contributes to shortening communication service downtime
【Multi-core Fiber Measurement Function】
Organizes the file names of each core into a table, significantly reducing work time
【Schedule Function]
The OTDR automatically measures at set intervals. No need for an operator to be present 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
● 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
● Measurement overlaid with a 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 in addition to continuous wave (CW) light, so it can be used as a light source for core comparison.
*Does not support multimode fiber.
Built-in Dummy Fiber
Can include a dummy fiber effective for detecting near-end abnormal loss.
*The built-in dummy fiber cannot be removed or replaced.
Optical Power Monitor
Convenient for simple optical power checks during commissioning tests or when a failure occurs.
*Does not support multimode fiber.
