400Gbps DP-xQAM LN Modulator, Fujitsu FTM7992HM
This optical modulator is a Ti:LiNbO3 DP-QPSK Single-Drive Mach-Zehnder modulator with modulation speed of up to 64Gbaud.
This modulator comprises 3dB coupler, two QPSK modulators, polarization rotator followed by the polarization beam combiner and the built-in monitor PD chips for automatic bias control (ABC) for the compensation system of DC-drift and other phenomena.
The 64Gbaud LN Modulator (FTM7992HM) is a 400Gbps PM-xQAM Lithium Niobate Modulator.
