Novel system and method for improving optical communications using transmission polarization diversity to reduce impairments in fiber transmissions.
UCF scientists have developed a novel and less costly system and device, to improve optical communication using polarization redundancy. The overall system is less complex than previous systems, since it uses simplified receivers, simple digital coding and signal processing.
Optical signals can degrade during transmission, significantly hindering the efficient transfer of data. A variety of strategies are therefore used to recover the unimpaired signal. Signal redundancy, obtained by using multiple transmitters and receivers is one such technique. The multiple receivers provide data redundancy (or diversity). They can also accurately reconstruct degraded signals by exploiting the differences in the versions of received data. Some of these multiple input, multiple output (MIMO) systems, use several antennas, while others use polarization to generate the redundancy. Diversity in polarization information helps to overcome impairments from optical fibers and scattering, which occurs in free-space communication. Although these techniques may be effective they require multiple transmitters and receivers, significantly increasing the cost of the system.
