Abstract
Methods and apparatus for increasing the operational distance of multimode fibers are disclosed. According to one aspect of the present invention, an optical transmitter includes a framer that frames data and a scrambler that scrambles the data after the data is framed. The optical transmitter also includes an encoder that applies a forward error correction algorithm to encode the data after the data is scrambled, as well as a source that transmits the data across the multimode fiber after the data is encoded.
