Dispersion-tolerant technique for the generation and transport of multi-band signals using a dual-drive Mach-Zehnder electro-optical modulator

This novel modulation technique allows to remotely feed a BS with information signals in its original base-band or IF frequency and modulated on a RF carrier at frequencies up to 60GHz using state-of-the-art components. This allows transmitting the same information from the Bs through a wireline access network and through a wireless access network. The technique allows long fiber spans due to its dirpersion-tolerant nature and simplifies the hardware requirements at the Control Station due to its frequency doubling capabilities.

This technique may be of interest for operators that want to operate simultaneously in different frequency bands due to service upgrading or unability to yield the cable plant, or to implement disaster-recovery strategies (e.g. the wireless link can be used as back-up for the wired link).
