ADVANTEST Q8384 600 to 1750 nm Optical Spectrum Analyzer

The Advantest Q8384 is a high-end optical spectrum analyzer using a monochromator developed by ADVANTEST and featuring a high dynamic range and a high wavelength resolution. It offers the highest level of performance with a 10pm wavelength resolution and a 20pm wavelength accuracy in the 1.55µm band. This enables precise measurement and evaluation of wavelength characteristics. The Q8384 has a wide dynamic range of 60dB at 0.2nm from the peak wavelength. Q8384 also integrates automatic NF measurement and arithmetic functions for optical fiber amplifiers with easy operation. Wavelengths can be measured with accuracy of ±20pm at 1530nm to 1570nm and ±40pm in the L band at 1570nm to 1610nm after calibration using a built-in calibration light source (Option 25). This enables high-spec laser diodes and optical filters used in DWDM to be evaluated accurately. The wavelength linearity is ±10pm at 1530nm to 1570nm enabling the spacing of wavelength-multiplexed signals to be measured accurately. Specifications. Wavelength Measurement range: 600 to 1700 nm.

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.
