The Yokogawa AQ1215A is a dual-wavelength Optical Time Domain Reflectometer (OTDR) for field testing and troubleshooting of single-mode fiber networks. Operating at 1310 nm and 1550 nm, it delivers dynamic range up to 42 dB and measurement capability to 512 km. The instrument combines a 5.7-inch color TFT LCD touchscreen with hard-key operation, integrated Li-ion battery (10-hour runtime), and modular architecture suited to access and enterprise fiber deployments.
