Efficient and scalable data transport system for DWDM cable TV networks

摘要

Arrangements are provided for optical transport of data. A scalable data transport system has an optical transmission system having a reconfigurable bit rate; an optical transmission fiber in communication with the optical transmission system; and an optical receiver system in communication with the optical transmission fiber. The optical transmission system is adapted to modulate an optical carrier with a subcarrier-multiplexed RF signal, and the subcarrier-multiplexed RF signal comprises a selectable plurality of RF signals that can be selected to configure a bit rate of the optical transmitter and reselected to reconfigure the bit rate of said optical transmitter.
