BRAND：Yokogawa
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 10-second startup help to minimize operations time and increase battery life. Yokogawa offers the world's only mini-OTDR with a built in dummy fiber option which is very effective at determining loss across the first connector and to determining return loss. Many OTDR users invest hundreds of dollars for handheld dummy fibers (also called launch reels) that are easily damaged, lost or stolen thereby increasing operations costs. Enhanced version of AQ7270 Series
Features:
_ Improved Waveform Quality
_ Increased Dynamic range
_ Wider Range of Optional Functions
_ Short Dead Zone (0.8 m)
