▼The waveform measurement function of the AQ7270OTDR has been further improved.
●Improved dynamic range, excelling in measuring medium-distance fibers and transmission lines with large losses such as splitters
●Clearer observation of splitter-through waveforms due to S/N improvement, etc.
●Battery life is twice that of the AQ7270 due to the power-saving design!!
●More than 1000 waveforms can be stored in the internal memory, and even more waveforms can be stored 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
【Relocation Support Function】　
Manages measurements before and after construction. Helps reduce communication service downtime
【Multi-core Fiber Measurement Function】
Tables the file names of each core, significantly reducing work time
【Schedule 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 attenuation during multi-wavelength measurement

▼Excellent cost performance,
Easy operation, further increasing work efficiency
Meets a wide range of measurement requirements from FTTH to metro and core networks
