The AQ8423Z is a unique dual-range optical amplifier analyzer. In conjunction with an external optical spectrum analyzer (OSA) and light sources (such as tunable laser sources or DFBs), the 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 AQ8423Z employs the proven "Pulse method" technique. It utilizes 1 MHz modulation frequency, which is high enough to suppress a rise of ASE (amplified spontaneous emission) level during off signal. The AQ8423Z can achieve very high accuracy in ASE measurement resulting in accurate NF measurement. Since the AQ8423Z can eliminate all DWDM signals simultaneously during ASE measurement, it can obtain measurement results under actual DWDM operational conditions.
