Abstract
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.
