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

• An integrated pair of ECDL tunable lasers for use as a local oscillator and another for self-test. Both lasers have industry-best linewidth and tuning range for any wavelength within the band

• Optical modulation analyzer software tolerates >5 MHz instantaneous signal laser linewidth – compatible with standard network tunable sources such as DBR and DFB lasers

• No laser phase or frequency locking required

• Smart polarization separation follows signal polarization

User-defined extensibility

• User access to internal functions with a direct MATLAB 2 interface

• Remote access available through Ethernet

• Superior user interface offers comprehensive visualization for ease-of-use combined with the power of MATLAB

• Optical modulation signal analyzer software included with OM1106 and OM4200 series products

400G and 1Tb/s superchannel support

• Multi-carrier software option allows user-definable superchannel setup

• Superchannel configuration allows user to define number of channels, channel frequency, and channel modulation format

• Test automation acquires complete measurements at each channel

• Integtrated measurement results allow easy channel-to-channel comparisons
