DESCRIPTION
The dual polarization IQ/QAM Transmitter is a high performance modulation evaluation unit that allows user to produce optical signals with complex modulation schemes (PM-QPSK, QAM, OFDM). It integrates high bandwidth PM-QPSK modulator and high speed RF drivers capable of dealing with data rate up to 128 Gbps. It features an embedded bias controller that allows to automatically set the modulator operating point.
