Optical transceiver measurements

The AQ2300 provides comprehensive optical transceiver evaluation by combining optical power measurement, optical attenuation, optical path switching, and ASE noise loading within a modular system. Multiple transceiver channels can be routed through optical switches, while variable optical attenuators enable controlled adjustment of optical signal levels. When combined with the AQ6151B Optical Wavelength Meter and the AQ6361/AQ6370E Optical Spectrum Analyzer, the system also delivers comprehensive wavelength and spectral analysis. The AQ23191A ASE Light Source can also be incorporated into the optical path to evaluate transceiver performance under controlled ASE noise-loading conditions.

Optical Fiber Amplifier Measurements

The AQ2300 supports optical fiber amplifier evaluation under wavelength-division multiplexed (WDM) conditions. Multiple optical signals at different wavelengths can be independently controlled, attenuated, and multiplexed to create realistic inputs for the amplifier under test. Combined with the AQ6370E/AQ6361 Optical Spectrum Analyzer, the system can evaluate gain, gain flatness, noise figure, and ASE across multiple wavelength channels. The AQ6370E/AQ6361 provides dedicated optical amplifier analysis capabilities for gain and noise figure evaluation, while the AQ2300 enables flexible control of optical power levels and measurement paths for multi-wavelength testing.
