▼Improved waveform measurement functions over the AQ7270 OTDR.
● Improved dynamic range, making it highly effective for measuring transmission lines with significant loss, such as medium-distance fibers and splitters.
● Enhanced S/N ratio allows for clear observation of waveforms beyond splitters.
● Equipped with stabilized light source and optical power monitor functions.
● Energy-efficient design doubles battery life compared to the AQ7270!!
● Internal memory stores over 1,000 waveforms, with further storage capacity using external USB memory.
● Large (8.4-inch) transflective color LCD, easy to see even under direct sunlight outdoors.
<Versatile OTDR Analysis Functions>
Multi-wavelength analysis, 2-wavelength synthesis, differential waveform analysis, and section analysis are possible.
<Facility Relocation Support Function>
Manages pre- and post-construction measurements, contributing to reduced communication service downtime.
<Multi-Core Fiber Measurement Function>
Creates a table of file names for each core, significantly reducing work time.
<Schedule Function>
The OTDR performs automatic measurements at set intervals. No constant operator attendance required even for long-term observations.
▼Excellent Cost Performance and
Easy Operation for Increased Work Efficiency
Meets a wide range of measurement requirements from FTTH to Metro and Core networks.
● 0.8m event dead zone
● High dynamic range up to 45dB
● Fast startup in under 10 seconds
▼User-friendly for beginners
Select the setting mode based on the operator's skill level.
<Simplified (Full-Auto) Mode> <Measurement Wizard Mode> <Detailed Mode>
● Switch wavelengths for continuous measurement - Multi-wavelength measurement
● Overlay measurement with reference waveform - Waveform fixing function
● USB functions
● Multi-core fiber measurement function
Stabilized Light Source
Can be used as a light source for loss measurement. In addition to continuous light (CW), it can also output 270Hz modulated light, making it useful as a light source for fiber identification.
*Does not support multi-mode fiber.
Optical Power Monitor
Convenient for simple checks of optical power during installation testing or when faults occur.
*Does not support multi-mode fiber.
