ANDO AQ7250 mini-OTDR Mainframe

The Ando AQ7250 mini-OTDR Mainframe is a compact, lightweight, and battery-powered. It offers a range of functions and capabilities ideal for field use. Its exceptionally wide dynamic range is particularly effective for measuring lines over long distances, as well as lines with heavy loss. In addition, an improved measurement algorithm drastically reduces measurement processing time. A wide range of optional equipment enables a single unit to be used for measurements on a variety of optical fiber lines. An optional high-speed printer or optical switch unit, as well as a visible light source or optical power meter can be installed on the main unit of the AQ7250. Specifications. Display: 7.2-inch color LCD (640 x 480 dots). Full-scale: 25m, 50m, 125m, 250m, 500m, 1km, 1.25km, 2km, 2.5km, 5km, 10km, 20km, 40km, 80km, 160km, 240km (Varies according to the unit). Shift: 0 to distance range. Resolution: Sampling resolution: 50 cm/min. Sample data count: 20,000 points max. Distance accuracy: ± (5.0 x 10-5 x measurement distance in meters + 1m). Group refractive index setting: 1.00000 to 1.99999, in 0.00001 steps. Distance measurement: Displays the relative one-way distance between any two given points, in two ranges on the waveform, in eight digits. Scale: 0.2 dB/div., 0.5 dB/div., 1 dB/div., 2 dB/div., 5 dB/div., and 7.5 dB/div. Shift: 0 to 68 dB. Read resolution: Max. 0.001 dB. Loss measurement: Displays one-way losses in steps of 0.001 dB to a maximum of 5 digits, Displays the relative one-way loss, loss per unit length, and splice loss between any two given points in two ranges on the waveform.

*This is a Web introductory price for one calibration of the ANDO AQ7250. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

Amplified Spontaneous Emission Source (ASE)
ASE, a process where spontaneously emitted radiation (luminescence) is amplified. In lasers and particularly in high-gain erbium-doped amplifiers, amplified spontaneous emission is usually an unwanted effect. It tends to limit the gain achievable in a single stage of a fiber optic amplifier to the order of 40–50 dB.

Dynamic Range
In a transmission system, the ratio of the overload level to the noise level of the system, usually expressed in dB. Ratio of the highest to lowest detectable signal of a system, expressed in dB.

Optical Power
Optical Power is usually measured in "dBm", or decibels referenced to one miliwatt of power. while loss is a relative reading, optical power is an absolute measurement, referenced to standards. You measure absolute power to test transmitters or receivers and relative power to test loss.

Relative Wavelength Accuracy
When randomly changing the wavelength and measuring the differences between the actual and displayed wavelengths, the relative wavelength accuracy is ± half the span between the maximum and the minimum value of all differences.

Wavelength
Wavelength is a term for the color of light, usually expressed in nanometers (nm) or microns (m). In Fiber Optics the wavelenghts mostly used are in the infrared region where the light is invisible to the human eye.
