AQ23411A Optical Switch (1×4)
Compact Optical Path Switching with Low Loss and High Repeatability
The AQ23411A is a compact 1 × 4 optical switch module for the AQ2300 Series Test Platform. It allows a common optical path to be connected to one of four ports, reducing the need to manually reconnect optical fibers during multiport measurements.
The module can be combined with AQ2300 Series light sources, optical power meters, and variable optical attenuators to build automated systems for optical component testing, insertion-loss measurement, and multiport device evaluation.

Static characterization of laser diode (LD) and photodiode modules
The AQ2300 streamlines the test by synchronizing source measure unit (SMU) and optical power meter (OPM) measurements during sweep measurements in a single test platform. enabling electrical and optical parameters to be synchronously acquired in a single platform. This built-in inter-channel synchronization enables efficient I-L characterization without additional external synchronization wiring. For more comprehensive optical characterization, the measurement system can be integrated with the AQ6151B Optical Wavelength Meter and AQ6361/AQ6370E Optical Spectrum Analyzer to evaluate wavelength and spectrum alongside electrical and optical power characteristics.

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.
