METHOD AND APPARATUS FOR GENERATING OPTICAL DUOBINARY SIGNALS WITH ENHANCED RECEIVER SENSITIVITY AND SPECTRAL EFFICIENCY |
摘要 |
An optical network transmitter comprising a fractional-bit delay module, an optical modulator coupled to the fractional-bit delay module, and a band-limiting optical filter coupled to the optical modulator. Also disclosed is a transmission system comprising a source configured to generate two complementary binary data streams, a fractional-bit delay module in communication with the source and configured to delay one of the complementary binary data streams, a modulation module in communication with the source and the fractional-bit delay module and configured to convert the undelayed complementary binary data streams and the delayed complementary binary data streams into a fractional-bit delayed optical duobinary signal, and a band-limiting node in communication with the modulation module and configured to filter and transmit the optical duobinary signal. |
