The Yokogawa AQ7275 is a mini-OTDR (optical time-domain reflectometer) featuring a very high trace quality, extended battery life, high measurement speed, wide dynamic range, and a number of new options and accessories.
Designed to ease the installation and maintenance of core, metro and access networks including FTTH (fibre to the home) and PON (passive optical networks), the AQ7275 offers excellent event separation capability and a very short dead zone - less than 80 cm - to enable multiple-event detection even when events are close to one another. Its high-speed operation optimises work efficiency, and automatic test functions enable installation operatives to execute tests easily and reliably.
Trace quality is enhanced by noise reduction on the real-time and average traces and the reduction of undershoot and step slope after a reflective event. Operating battery life has been increased compared with the earlier AQ7270 model and the dynamic range has been boosted to 38-40 dB for the triple and quad wavelength units.
Other performance enhancements include a typical measurement time of only 19 sec for a 5 km range with 50 cm sampling and 2^14 averaging - three times faster than current models - and an improved auto-search capability resulting from the trace-quality improvement combined with a new algorithm.
New options and accessories include stabilised light sources, an angled connector, a visible light source, and a large-capacity external lithium battery. The stabilised light sources, designed for loss measurements, are available with output levels of +3 dBm ± 1.5 dB for 1310/1550 nm measurements and 0 dBm ± 1.5 dB for 1650 nm measurements.
