    摘要: An optical duobinary transmission system and method are provided for transmitting optical duobinary signals across an optical transmission link having residual dispersion. The system includes a transmitter having a low bandwidth modulator, adapted to provide filtering for low pass filtered duobinary transmission. The transmission link is designed such that the residual dispersion of the transmission link substantially compensates for signal distortion from the transmitter.

    摘要: A device and method for processing a signal e.g. equalizing a signal, is disclosed. Such processing involves dividing a signal into two portions that each traverses a wavepath and then are combined. The respective wavepaths impose a non-linear frequency-versus-phase dependency on a signal portion. The frequency-versus-phase dependencies that characterize the respective wavepaths are similar in shape but inverted from each other. A processed signal has significantly improved signal-to-noise ratio.

    摘要: An optical modulator is overdriven to increase its nonlinearity and therefore improve its response as it pertains to differential phase shift keyed (DPSK) transmission and a method of operating the same. In one embodiment, the MZM includes an MZM drive circuit coupled to the electrodes and configured to deliver to the electrode a DPSK drive signal bearing digital data and having a voltage that exceeds a normal drive voltage of the MZM by at least about 20%.
