DQPSK 40Gbps LiNbO3 External Modulator
General Description
•40Gbps (22Gbaud) Mach-Zehnder modulator for “DQPSK” transmission format
•Wide EO Bandwidth equivalent to conventional 40G Modulator for each MZI’s
•Low drive voltage: < 4V (Dual drive)
•The DC bias is adjusted at the separate DC port of the modulator.
•Built-in a monitor PD for auto bias control
•Applications:
-40Gbps optical transmission equipment (DQPSK)
-DWDM optical transmission equipment
-Measurement equipment for high speed telecommunications
