MZM Transmitter, PAM4/NRZ/OOK/RZ/BPSK/DPSK/ODB/Pulse Multi-format


The optical MZM (Mach-Zehnder Modulator) transmitter is a high performance modulation evaluation unit that allows user to produce optical signals with complex modulation schemes (NRZ, OOK, PSK). And PAM4 performance is an option available upon request. It integrates high bandwidth optical modulator capable of dealing with data rate up to 40Gbps. It features an embedded bias controller that allows to automatically set the modulator operating point.
