The OM4245 Optical Modulation Analyzer (OMA) is a 45 GHz 1550 nm (C- and L- band) fiber-optic test system for visualization and measurement of complex modulated signals, offering a complete solution to testing both coherent and direct-detected transmission systems. The OM4245 consists of a polarization- and phase-diverse receiver and analysis software enabling simultaneous measurement of modulation formats important to advanced fiber communications, including polarization-multiplexed (PM) formats such as QPSK, 8QAM, 16QAM, PAM4, and many others. The OMA software performs all calibration and processing functions to enable real-time burst-mode constellation diagram display, eye-diagram display, Poincaré sphere, and bit-error detection.
Key features
Unparalleled flexibility
Optical modulation analyzer architecture is compatible with both real-time and equivalent-time oscilloscopes 1
Complete coherent signal analysis system for polarization-multiplexed QPSK, offset QPSK, QAM, differential BPSK/QPSK, and other advanced modulation formats
Displays constellation diagrams, phase eye diagrams, Q-factor, Q-plot, spectral plots, Poincaré Sphere, signal vs. time, laser phase characteristics, BER, with additional plots and analyses available through the MATLAB interface
Measures polarization mode dispersion (PMD) of arbitrary order with most polarization multiplexed signals
Precise optical receiver
Precise coherent receiver hardware provides minimal variation over temperature and time for a high degree of accuracy and high-stability, polarization-diverse, optical field detection
Highly linear photo detection allows operation at high local oscillator and signal power levels to eliminate electrical amplification
