摘要：
The present invention describes systems and methods of providing optical information transmission systems. An exemplary embodiment of the present invention includes a precoder configured to differentially encode a binary data signal, a duobinary encoder configured to encode the differentially encoded binary data signal as a three-level duobinary signal, an electrical-to-optical conversion unit configured to convert the three-level duobinary signal into a two-level optical signal, and an optical upconversion unit configured to modulate the two-level optical signal onto a higher frequency optical carrier signal and transmit the modulated higher frequency optical carrier signal onto an optical transmission medium.
