An apparatus and method are provided for transmitting an optical duobinary signal using a low bandwidth modulator having a bandwidth of less than about 60% of the transmission bit rate of the transmitter. The modulator is adapted to provide low pass filtering for low pass filtered duobinary transmission in an optical fiber transmission system having residual dispersion.

Apparatus and method for duobinary transmission

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.

Duobinary transmission system and method

Methods and arrangements are disclosed herein for optically storing data from a serial optical bit stream. As each bit of the optical stream is received it is applied to an optical storage medium e.g., lithium niobate, along with a reference beam. The angle of the reference beam is changed in synchronism with the received optical bits to create identifiable interference patterns for each bit.
