The AQ7275 Optical Time Reflectometer (OTDR) is ideal for use in a wide variety of optical fiber installation and maintenance applications. Increased efficiency and a quick start-up help to maximize time spent on operations. With the 10-second startup, the AQ7275 is ready to perform when you are.

literature & technical specifications

Yokogawa's Optical Time Reflectometer is ideally suited to your varying needs:

• Wide Range of Modules Available
• Supporting FTTH to Metro, Core Network
• High Dynamic Range (45dB)
• Short Dead Zone (0.8 m)

Key Features:

• 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 (735041) 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!
