Time-Resolved Error Vector Magnitude for Transmitter Mask Testing in Coherent Optical Transmission Systems
Time-Resolved Optical Transmission Systems Mask Testing
2015/5/15
We propose a novel transition-sensitive measurement approach for coherent optical systems. The time-resolved error vector magnitude (EVM), combined with mask testing, is a powerful tool for pass/fail ...
Frequency Domain Equalization with Minimum Complexity in Coherent Optical Transmission Systems
Fiber optics links subsystems Optical communications
2015/6/10
For chip-design of a frequency-domain equalizer, a simple procedure to minimize the number of multiplications is shown. Considerations include recent improvements of FFT-algorithms.
Efficient Digital Backpropagation for PDM-CO-OFDM Optical Transmission Systems
Fiber optics communications Modulation
2015/6/9
We demonstrated experimentally that computationally-efficient digital nonlinearity compensation using backpropagation can increase the nonlinear tolerance of 61.7 Gb/s PDM-CO-OFDM by 2.2 dB in a 500 k...
Concatenated QC-LDPC and SPC Codes for 100 Gbps Ultra Long-Haul Optical Transmission Systems
Fiber optics communications Optical communications
2015/6/8
We propose and investigate a novel FEC coding scheme based on a concatenation of QC-LDPC with single-parity-check codes. High performance of a Q-limit of 5.8 dB with 20.5% overhead has been achieved w...
100G Coherent DWDM Transponder Module Enabling Seamless Upgrade of Long Haul Optical Transmission Systems
Optical communications Coherent communications
2015/6/5
We review recent trends and progress in 100G module and subsystem development for long haul DWDM applications and explore similarities and differences between these 100G products and those developed a...
