   ANDO AQ2140 (AQ-2140)   Description / Specification:    
ANDO AQ2140 Optical Multimeter Mainframe

The Ando AQ2140 optical multimeter was developed to serve as a basic optical measurement instrument in a wide range of applications from R&D to optical fiber and component manufacture, and construction and maintenance. This single unit provides high precision, powerful functions and high-speed measurement, making it possible to use it as an optical power meter, a stabilized light source, a loss test set or a return loss measurement instrument. Sensor Features. Sensor unit; Measurement accuracy of ±2.5% is guaranteed under the reference conditions. Covers a wide waveband from 400 to 1870nm, and provides a dynamic range of 100dB or more for loss measurement. (It depends on sensors.) The AQ2733 and AQ2734 sensor units achieve a low polarization dependence of 0.02 dB p-p or less. The AQ2734 sensor unit uses a photodiode with flat wavelength sensitivity from 1300 to 1800nm, for accurate measurement at 1650nm as well. Light source unit; The LD unit has an internal isolator that maintain optical output level stability at ±0.003 dB. Optical power can be decreased in 0.1 dB steps to 6.0dB. A wide variety of optical connectors can be used just be exchanging the universal and connector adapters (AQ4214 excluded). Return loss unit; Because internal self-reflectance data is stored by individual units in memory to correct operations, even high-reflectance attenuation can be measured with excellent accuracy. The internal high-stability sensor can be used together with the LD unit to provide stable reflectance attenuation measurement. Mounted with a return loss unit and LD unit, the display will show reflectance attenuation after measurement of reference reflectance by merely disconnecting the measured fiber cable. Mainframe. Unit display Absolule, dBm, mW, uW, nW, pW, Relative: dB, Comparative: None. Range: Automatic or fixed (up/down). Measurement mode: Seleclable, CW light/chopped light (270Hz, 1kHz, 2kHz).

Bit Error Ratio (BER)
Bit Error Ratio (BER) is the ratio of errors caused by the number of bits in a data stream that have been altered due to noise, interference, distoriton or bit synchronization errors.

Variation of insertion loss on the passband of an optical device.

Polarization Dependent Loss (PDL)
Polarization Dependent Loss is the difference between the maximum and minimum values of loss due to the variation of the polarization states of light propagating through a device. PDL is expressed in decibels. Calculated by; PDL = 10 log10 (Ep/Es), where EP and ES are the measured diffraction efficiencies for P- and S-plane polarized incident light, respectively.

Return Loss (RL)
Return Loss (RL) is the ratio of the incident power to the reflected power expressed in dB. RL = 10log (Pin/Pback)

Wavelength Resolution
Wavelength Resolution is the smallest possible displayed wavelength increment/decrement.
