Frequency-domain equalization (FDE) has been attracting much attention for high-speed long-haul transmission over fiber-optic channels. Two FDE configurations for coherent optical transmission are pre...
Nonlinear compensation with digital back-propagation can improve Q-factor by more than 1dB, proven by experiments. Simplification of propagation model is the key to suppress circuit size, whereas stra...
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 ...
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.
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...
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...
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...
We evaluate fiber fuse characteristics of bend-insensitive optical fibers and show that hole-assisted fiber(HAF) is applicable as fiber fuse stopper in high-power optical transmission systems. We also...
