Title:
OPTICAL DUOBINARY TRANSMITTER AND METHOD
Document Type and Number:
WIPO Patent Application WO2005004358
Kind Code:
B1
Abstract:
There is provided an optical duobinary (ODB) transmission system, including a duobinary precoder receiving data signals and converting the signals into first and second different digital signals each composed of two level voltages; a duobinary encoder fed by the precoder for converting the digital signals into three level analog signals, and a close loop control circuit for maintaining equal drive voltages for driving a Mach Zehnder Modulator (MZM). A method of encoding NRZ data for optical duobinary (ODB) transmission is also provided.
