Optical Time Domain Reflectometer Yokogawa AQ7275 YOKOGAWA OTDR
Produst Function:
-
Improved Wavelength Quality Increase the efficiency of fiber installation & maintenance
-
Event Dead Zone 0.8 m
Accompanying the rapid proliferation of FTTH is a growing need for detection of reflective events arising from short distance mechanical connections. The AQ7275’s short event dead zone enables detection of closely spaced events in cables installed in offices and customer premises.
-
High Dynamic Range up to 40 dB
The newly added 3-wavelength model (735037) and 4-wavelength model (735040) can achieve
the dynamic range of 40 dB. This high dynamic range is effective in measuring a transmission
line consisting of long fiber cables and a splitter with a large loss.
-
Quick Startup within 10 Seconds
Now measurements can be started quickly upon arrival at the site. 10 seconds to power-up
from completely OFF to fully ON! With such a fast power-up time, battery life can be extended by turning the power off while not in use at the job site without any concern about the power-up time when the next job is ready. It’s ready when you’re ready!
