ADVANTEST Q8347 Evaluates Optical Narrow-Band-Pass Filters For WDM Optical Spectrum Analyzer
Description of ADVANTEST Q8347
- The Q8347 spectrum analyzer enhanced the performance of spectrum analyzer employing a Fourier spectrum system with a Michelson interferometer. The Q8347 achieves wavelength resolution of 0.01 nm and wavelength accuracy of ±0.01 nm (resolution of 1 GHz and accuracy of ±1 GHz in optical frequency mode) at the 1550 nm spectrum band. In addition, the Q8347 is capable of accurately measuring the each wavelength of optical wavelength division multiplexing (WDM) transmission signal by separating the spectrums. It is especially suitable for evaluating characteristics of optical narrow-band-pass filters used for WDM like AWG and Fiber gratings. Also, the Q8347 is powerful for analyzing chirps from LDs and Soliton transmission.

- Input Connector :FC Connector (Internal Fiber:PC Rubbed, GI 50/125)
- Data Outpu:tGP-IB Equipped as Standard, Direct Plotter Output, Built-in Printer (Printing Speed: 8 sec. or less)
Optical frequency can displayed
- In addition to general wavelength display mode, a measured spectrum can be displayed as optical frequencies. As light can be directly read in units of THz, it is useful for measuring optical WDM and chirps from LDs, and for analyzing Soliton transmission system.
Coherence analysis of ±165 mm
- As the Q8347 uses a Michelson interferometer, the system is capable of performing coherence analysis. This function allows easy evaluation of noise suppression performance of LDs for optical discs. Furthermore, the stroke of the interferometer can be greatly increased to allow analysis to be made in a range of ±165 mm. Thus, more detailed analysis can be mode, over and above the conventional secondary maximum peak value (α value).
Curve fitting function
- The Q8347 provides curve fitting with sech2 and Gaussian functions. Thus, it is useful for spectrum analysis of Soliton transmission system.
