Single sideband dense wavelength division multiplexed optical transmission scheme |
摘要 |
A single-sideband dense wavelength division multiplexing optical communication system and method are disclosed that achieve an increased throughput by moving the carrier wavelengths from the center of the corresponding channel band and suppressing one of the sidebands associated with each channel band. Most of the power is placed in the selected sideband and additional bandwidth is available to increase the throughput within the selected sideband. An electrical signal is modulated to provide a passband signal without low frequency components. The disclosed modulation scheme shifts the carrier wavelengths within the wavelength grid to provide additional bandwidth for the selected sideband in each channel band. Generally, the bandwidth (and thus, throughput) that is available to the selected sideband increases by a factor of two.
