1-Tb/s Large Girth LDPC-Coded Coherent Optical OFDM Transmission over 1040-km Standard Single-Mode Fiber
Large Girth LDPC-Coded Coherent Optical OFDM Standard Single-Mode Fiber
2015/5/15
We experimentally demonstrate 1-Tb/s CO-OFDM transmission over 1040-km standard single-mode fiber using 50% overhead girth-12 LDPC-coded 16-QAM. More than 4-dB improvement in OSNR sensitivity is achie...
We consider application of the discrete Fourier transform-spread orthogonal frequency-division multiplexing (DFT-spread OFDM) technique to high-speed fiber optic communications. The DFT-spread OFDM is...
Sub-Rate Sampling in 100 Gb/s Coherent Optical Receivers
Fiber Optics Communications Coherent communications
2015/6/9
We investigate the feasibility of ADC sampling rate below 2x versus optical/electrical bandwidths in 100G-PM-QPSK coherent receivers. We find <0.5 dB penalty for rates down to 5/4x even for dispersion...
