The Yokogawa AQ1200E is a handheld OTDR designed for field testing and maintenance of single-mode optical fiber networks. Operating at 1310 nm, 1550 nm, and 1625 nm, it delivers dynamic range up to 32 dB and sub-meter event resolution for precise fault detection in live networks. The built-in cutoff filter at 1625 nm enables non-disruptive measurements on in-service PON systems without interrupting active traffic.
