APEX Technologies has launched its AP264XB Optical Complex Spectrum Analyser (OCSA), which can be used as an optical modulation analyser and as an optical spectrum analyser.
As an optical modulation Analyser, it can measure chirp, phase, alpha parameter or pulse shape as a function of time. Furthermore, it can display constellation, phase eye diagram, intensity eye diagram, EVM and BER estimation.
It it is also capable of measuring any modulation format and any baud rate cycling signal modulated with a PRBS pattern or long pattern. Its measurement speed is ~1Hz. It can separately and simultaneously measure two polarisation axes and analyse Pol-Mux modulated formats.
As an optical spectrum analyser, the equipment combines high wavelength bandwidth resolution filter 0.16pm (20MHz), high wavelength accuracy +/-3pm and high dynamic range 83dB. Two internal channels allow the measurement of both polarisation axes simultaneously.
The user can also operate this OCSA as an independent high performance tunable laser source or as a component analyser to characterise any optical component.
