▼The waveform measurement functions of the AQ7270 OTDR have been further improved.
● Improved dynamic range, effective for measuring transmission lines with significant loss, such as medium-distance fibers and splitters.
● Clear observation of waveforms beyond splitters due to improved S/N ratio, etc.
● Equipped with stabilized light source and optical power monitor functions.
● Power-saving design doubles the battery life compared to the AQ7270!!
● Internal memory can store over 1,000 waveforms, with further capacity available via external USB memory.
● Large, 8.4-inch transflective color LCD, easy to view even under direct outdoor sunlight.
<Versatile OTDR Analysis Functions>
Multi-wavelength analysis, 2-wavelength synthesis, differential waveform analysis, and section analysis are possible.
<Facility Relocation Support Function>
Manages measurements before and after construction, contributing to reduced communication service downtime.
<Multi-Fiber Measurement Function>
Creates tables for each fiber's file name, significantly reducing work time.
<Schedule Function>
Automated OTDR measurements at set intervals. No constant operator presence required for long-term observations.
▼Excellent cost performance,
simple operation, further improving work efficiency.
Meets a wide range of measurement requirements from FTTH to Metro and Core networks.
● 0.8m event dead zone
● Max 45dB high dynamic range
● Fast startup in under 10 seconds
▼Easy-to-use operability even for beginners
Selectable setting modes based on operator skill level
<Simple (Full Auto) Mode> <Measurement Wizard Mode> <Detailed Mode>
● Multi-wavelength measurement by switching wavelengths
● Waveform fixing function for comparing with reference waveforms
● USB functions
● Multi-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 suitable as a light source for fiber identification.
*Not compatible with multi-mode fiber.
Optical Power Monitor
Convenient for simple checks of optical power during opening tests or when a failure occurs.
*Not compatible with multi-mode fiber.
