40Gbps PM-BPSK Modulator, Fujitsu FTM7980EDA, Lithium Niobate DP-BPSK Modulator

This optical modulator is a Ti:LiNbO3 DP-BPSK Dual-Drive Mach-Zehnder modulator 

with modulation speed of up to 21.5Gbaud. This modulator comprises 3dB coupler, 

彩63彩票主页two BPSK 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 FTM7980EDA modulator supports the advanced Dual Polarization-DPSK modulation 

scheme. In general, the DPSK format is particularly suitable for 40G ULH applications; in 

combination with coherent detection the 2*20G polarization multiplexed version is very 

attractive as an upgrade to existing 10G links to a 40G transmission rate without 

modification of the link。
