Optical Amplifier Analyzer AQ8423Z

The Ando AQ8423Z is a unique dual-range Optical Amplifier Analyzer. In conjunction with an external Optical Spectrum Analyzer (typically Ando AQ6317C) and light sources (such as tunable laser sources or DWDM-DFBs), the Ando AQ8423Z can measure gain and noise figure (NF) of optical amplifiers both in C-band and L-band. Two testing wavelength ranges can be switched internally by simple operation.

The Ando AQ8423Z employs the proven "Pulse Method" technique. It utilizes 1MHz modulation frequency, which is high enough to suppress a rise of ASE level during off signal. The Ando AQ8423Z can achieve high accuracy in ASE measurement resulting in accurate NF measurement. Since the Ando AQ8423Z can eliminate all DWDM signals simultaneously during ASE measurement, it can obtain measurement results under actual DWDM operational conditions.
