   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.

Chromatic Dispersion
Chromatic Dispersion is a broadening of the input signal as it travels down the length of the fiber. Chromatic Dispersion results from a variation in propagation delay with wavelength, and is affected by fiber materials and dimensions.

Detector
A Detector is a signal conversion device that converts power from one form to another, such as from optical power to electrical power

Jitter
Jitter in technical terms is the deviation in or displacement of some aspect of the pulses in a high-frequency digital signal. Jitter is the time variation of a periodic signal in electronics and telecommunications, often in relation to a reference clock source. Jitter may be observed in characteristics such as the frequency of successive pulses, the signal amplitude, or phase of periodic signals. Jitter is a significant, and usually undesired, factor in the design of almost all communications links (e.g., USB, PCI-e, SATA, OC-48). In clock recovery applications it is called timing jitter.

Polarization Mode Dispersion (PMD)
Polarization mode dispersion (PMD) is a form of modal dispersion where two different polarizations of light in a waveguide, which normally travel at the same speed, travel at different speeds due to random imperfections and asymmetries, causing random spreading of optical pulses. It is he difference between the maximum and minimum values of loss typically measured in ps/km^1/2.
