   ANDO AQ7250   Description / Specification:    
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.

dBm
Optical power referenced to 1 millimatt

Multimode Fiber
Multimode Fiber has a large core (almost always 62.5 microns - a micron is one one millionth of a meter - but sometimes 50 microns) and is used with LED sources at wavelengths of 850 and 1300 nm for short distance, lower speed networks like LANs. Both multimode and singlemode fiber have an outside diameter of 125 microns - about 5 thousandths of an inch - just slightly larger than a human hair.

Power Repeatability
Power Repeatability is the random uncertainty in reproducing the power level after changing and re-setting the power level. The power repeatability is ± half the span (in dB) between the highest and lowest actual power. Note: - The long-term power repeatability can be obtained by taken the power repeatability and power stability into account.

Refractive Index
The refractive index or index of refraction of a substance is a measure of the speed of light in that substance. It is expressed as a ratio of the speed of light in vacuum relative to that in the considered medium. The velocity at which light travels in vacuum is a physical constant, and the fastest speed at which energy or information can be transferred. However, light travels slower through any given material, or medium, that is not vacuum.

Total insertion loss
A measure of the loss of light within an optical component
