CORX – Coherent IQ Receiver

The CORX Coherent Optical Receiver is a turn-key instrument designed to interface with any real-time oscilloscope by providing 4 single-ended RF outputs. It allows the coherent detection of polarization-multiplexed optical signals in the C-Band by mixing the test signal with a built-in local laser oscillator. It is designed as a reference receiver for transmitter characterization and analysis of IQ modulated optical signals in the C-Band. Available with bandwidth options of 60 GHz, 40 GHz and 20 GHz, the CORX enables the processing of Terabit-class signals and baud rates beyond 120 GBaud.
