Demonstration of dispersion-tolerant 34 Mbit/s data transmission in electro-optically upconverted 28 GHz LMDS fiber-optic link

It is shown experimentally that the dispersion-induced power penalty may be sharply reduced in electro-optical upconverted millimeter-wave optical links by biasing the Mach-Zehnder electrooptical modulators at the minimum transmission point rather than at the quadrature point. A 34 Mbits/s NRZ signal impressed on a 1 GHz subcarrier was optically upconverted to 28 GHz and transmitted through 73 km of standard single-mode optical fiber with minor impact of fiber dispersion.
