The Yokogawa AQ1205F is a tri-wavelength OTDR designed for installation, commissioning, and maintenance of optical fiber networks across 1310 nm, 1550 nm, and 1650 nm. This compact, lightweight field tester delivers high dynamic range and superior waveform quality, enabling precise measurements in Passive Optical Network (PON) systems with high-port-count splitters and significant insertion loss. The instrument’s short event dead zone of 0.75 m resolves closely spaced connectors in FTTx and access networks, while dual-port architecture segregates communication wavelengths (1310/1550 nm) from dedicated maintenance wavelength (1650 nm) operation.
