the FTM7967EQA modulator supports the generally Accepted Dual Polarization-QPSK modulation scheme; each of four parallel MZI's Running at speeds of 10 Gbaud (plus FEC). the driver electronics for each MZI Is " simply" 10G, giving a cost advantage over other 40G formats.

the very advanced, spectrally highly efficient QPSK modulation format, combined with the polarization multiplexing scheme, Guarantees compatibility with 50GHz optical channel spacing, thus allowing 40G Transmission over existing 10G network infrastructure – without specific Modifications. the FTM7967EQA uses very Advanced chip and packaging technologies that have evolved from Fujitsu's Extremely reliable and high-performing standard MZI modulators. A meticulous Chip design features low insertion loss (with very small polarization dependent Loss) as well as an extended bandwidth and a quasi-linear electro-optic Roll-off.
