ADVANTEST Q8347 350 to 1750 nm  Optical Spectrum Analyzer

The Advantest Q8347 Optical Spectrum Analyzer exhibits its full capabilities in evaluation of WDM (wavelength division multiplex) transmission systems, ultra high-speed optical transmission systems and narrow-band optical filters, extending applications for the coming information society. Although higher resolution can be obtained with optical spectrum analyzers using a Fabry-Perot interferometer, they had problems such as narrow measuring spans and low wavelength accuracy. Designed based on improvements on existing spectrum analyzers employing a Fourier spectrum system with a Michelson interferometer, the Q8347 optical spectrum analyzer has attained high wavelength resolution and measurement accuracy. The Advantest Q8347 can achieved a high resolution of 0.01 nm and high accuracy of ± 0.01 nm (1 GHz resolution and ± 1 GHz accuracy in optical frequency display mode) at 1.55 µm band. Signals of optical wavelength division multiplexing (WDM) transmission can be separated for accurate wavelength measurement. In addition, it is powerful for analyzing chirps from laser diodes and Soliton transmission, and for measuring the output of narrow-band filters. At short wavelengths, higher resolution can be obtained. At the 500 nm band, a resolution of 0.001 nm is achieved and this is suitable for analysis of blue laser diodes. Specifications. Measurement range: 0.35 to 1.75 µm. Maximum resolution (High-resolution mode): Approx. 0.01 nm/1.55 µm, Approx. 0.003 nm/0.85 µm. Wavelength Accuracy (High-resolution mode): ± 0.01 nm or less. Wavelength Span 0.01 nm/DIV to 140 nm/DIV. Measurement range (Input sensitivity): -72 to +10 dBm (1.2 to 1.6 µm), -42 to +10 dBm (0.35 to 1.75 µm). Accuracy: ± 1.0 dB (780 nm), ± 0.7 dB (1310 nm, 1550nm) and input level -10 dBm. Measurement time: 1 second or less.

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.
