Jay Wiesenfeld has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7848658
    Abstract: A system and method for increasing transmission distance and/or transmission data rates using tedons and an encoding scheme to reduce the number of ones in a data signal is described. For example, the method for increasing transmission distance and transmission data rate of a fiber optical communications link using tedons includes the steps of encoding a data signal to be transmitted using an encoding scheme that reduces a number of ones in the data signal, transmitting the encoded data signal over the fiber optical communications link, receiving the encoded data signal and decoding the encoded data signal.
    Type: Grant

  • Patent number: 6509993
    Abstract: An optical transmission system and method uses large-bandwidth optical signals that rapidly disperse in a transmission medium, such as an optical fiber, to reduce the effects of non-linearities in the transmission medium on the optical signal. The frequency bandwidth of the optical signals can be widened by chirping the optical signals, although other methods are possible. Optical signals in adjacent channels, such as in wavelength division multiplexing, can overlap to some extent without significant effect on the transmitted signal quality. Optical filtering at the receiver can extract partially overlapping signals as well as compensate for residual dispersion and/or dispersion slope in the transmission system.
