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
