   ANDO AQ-3140 (AQ3140)   Description / Specification:    
ANDO AQ-3140 Optical Variable Attenuator

The Ando AQ-3140 is a highly precise optical variable attenuator, ideal for measurements of optical loss characteristics and transmission error rate in evaluating single-mode fiber-optic communications equipment. The Ando AQ3140 contains both a step attenuator arid a continuous attenuator for precise optical level adjustments up to 65dB. Non-reflective coating on optical surface enables the AQ-3140 to achieve the high return loss of 40dB. This is suitable for measuring systems having optical device like light source that is susceptible to reflected light. Specifications. Wavelength: 1300 nm / 1550 nm. Max. attenuation: 65 dB. Attenuation: 0 to 50dB in 10dB steps and; 0 to 15dB continuously variable. Insertion loss: 3dB or less (at attenuation setting of 0 dB). Return loss: 40dB or more. Connector: FC-Super PC. Applicable fibers: SM (10/125 um).

*This is a Web introductory price for one calibration of the ANDO AQ-3140. 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.

Coherence Time
Average time for the wave train to lose its phase realtionships

Fiber Bragg Grating (FBG)
A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others. This is achieved by adding a periodic variation to the refractive index of the fiber core, which generates a wavelength specific dielectric mirror. A fiber Bragg grating can therefore be used as an inline optical filter to block certain wavelengths, or as a wavelength-specific reflector.

Modulation
Modulation is the process by which the characteristic of one wave (the carrier) is modified by another. Adding information into pulses of light.

Power Linearity
When changing the power level and measuring the differences (in dB) between actual and displayed power levels, the power linearity is ± half the span (in dB) between the maximum and the minimum value of all differences.

Stability
Stability is the extent to which a specified property, characteristic, or parameter of a substance, device, or apparatus, such as a fiber optic transmission system, remains fixed with the passage of time or with varying environmental conditions.
