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, 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.
