The Yokogawa AQ7286J is a four-wavelength Optical Time Domain Reflectometer (OTDR) engineered for fiber optic network construction, troubleshooting, and quality control across single-mode installations. Operating at 1310 nm, 1383 nm, 1550 nm, and 1625 nm in a single port, it delivers dynamic range performance of 42 dB (1310 nm), 40 dB (1550 nm), and 39 dB (1383/1625 nm typ.). The instrument achieves event dead zone of 0.6 m and attenuation dead zones ranging from 3.5 m to 4 m depending on wavelength. Trace acquisition occurs in 30 seconds to 3 minutes, with results stored internally (>1000 waveforms) or exported via USB and SD card. The 8.4-inch color TFT LCD (800 x 600 resolution) features multi-touch capacitive control for intuitive operation. Wavelength tolerance meets IEC 60793-1-40 at ±15 nm standard or ±10 nm optional. The modular architecture supports detachable optical power meter (OPM) modules and visible light source (VLS) modules from the AQ7280 series. AC power input spans 100 to 240 VAC, 50 to 60 Hz, with Li-ion battery backup. Compact dimensions of 211 x 110 x 32 mm (W x H x D) and 420–460 g mass enable field deployment across access networks, core infrastructure, and FTTH installations. Compatible with AQ7933 OTDR Emulation Software for trace re-analysis and reporting workflows.
