Yokogawa AQ7275 OTDR

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 refl ective 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 fi ber 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.

Features:

• Wide range of models available
• Supporting FTTH to core networks
• Short dead zone (0.75 m)
