Persistent Channel Power Deviations in Constant Gain Amplified Long-Chain ROADM Networks
Channel Powe Deviations Constant Gain Long-Chain ROADM Networks
2015/5/15
Numerical simulations of the evolution of the channel power response to power adjustments in constant gain amplified degree-2 ROADM networks demonstrate novel persistent and periodic distant-dependent...
Constant Envelope Optical OFDM for Improved Nonlinear and Phase Noise Tolerance
Fiber optics communication Phase Modulation
2015/5/25
We introduce a new concept of OFDM transmission with constant envelope and coherent detection to reduce the sensitivity of OFDM signals to nonlinear effects and phase noise.
Two-Stage Constant Modulus Algorithm Equalizer for Singularity Free Operation and Optical Performance Monitoring in Optical Coherent Receiver
Fiber optics communications Coherent communications Polarization
2015/6/5
A two-stage constant-modulus-algorithm (CMA) equalizer for polarization-demultiplexing in a polarization-division-multiplexed coherent receiver is demonstrated. The equalizer eliminates the singularit...
QAM Adaptation of Constant-Modulus Algorithm and Differential Phase Compensation for Polarization Demultiplex in Coherent Receiver
QAM Adaptation Constant-Modulus Algorithm Differential Phase Compensation Polarization Demultiplex Coherent Receiver
2015/7/16
The constant modulus algorithm is adapted for QAM signals and complemented with a differential phase compensation. This triples polarization control speed and doubles laser linewidth tolerance.
