111 Gb/s Transmission with Compensation of FBG-induced Phase Ripple Enabled by Coherent Detection and Digital Signal Processing
FBG-induced Phase Ripple Enabled Coherent Detection Digital Signal Processing
2009/7/17
We demonstrate that coherent detection combined with digital signal processing can completely compensate for FBG induced phase-ripple. We report penalty free transmission of 40x111-Gb/s POLMUX-RZ-DQPS...
Use of the Zero Forcing Method for Compensation of Polarization Dependent Loss in Coherent Fiber-Optic Links
Zero Forcing Method Compensation Polarization Dependent Coherent Fiber-Optic Links
2009/7/17
We show that a zero forcing receiver can be used to achieve nearly optimal performance in coherent polarization multiplexed systems. The advantage is in the receiver simplicity relative to the joint d...
Joint CD and PMD Compensation for Direct-Detected Optical OFDM Using Polarization-Time Coding Approach
Joint CD PMD Compensation Direct-Detected Optical OFDM Polarization-Time Coding Approach
2009/7/14
We demonstrate a polarization-time coding method for direct-detected OFDM, which provides the signal with immunity against both fibre CD and PMD effects. Further dynamic PTC method is introduced for t...
