ADVANTEST Q8326 480 to 1650 nm Optical Wavelength Meter

The Advantest Q8326 optical wavelength meter enables sigh-precision measurement of laser and light emitting diode wavelengths and frequency. The key features of the Q8326 are; Wide measurement ranges for wavelengths and frequencies: 480 nm to 1650 nm, and 181 THz to 625 THz, respectively. Highly accurate wavelength measurement: ±2 ppm ±l count. A high speed sampling rate of 5 measurements/sec. GPIB and D/A conversion analog output is standard. Specifications. Wavelength Measurable range: 480 nm to 1650 nm. Wavelength Accuracy: ± 2 ppm ± l count. Wavelength Display resolution: 1 nm to 0.0001 nm. Level Sensitivity: -15 dBm (480 nm to 600 nm), -25 dBm (600 nm to 1650 nm), -30 dBm (1200 nm to 1650 nm). Maximum input level: +10 dBm. Measurement time: 0.2 sec. Average Function: Displays the results of the moving average with an averaging count of 10. Deviation Measurement Function: Displays the deviation from the standard measured value. Input Fiber: 50/125 um GI fiber (Recommended), 9.5/125 um SM fiber (Recommended).

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 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 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.
