TL;DR: Forward error correction performance down to 10−15 bit error rate (BER) of a concatenated staircase and Hamming code (CSHC), which was recently proposed for the first 400G inter-data center interconnect standard, is verified with a 50-piece field-programmable gate array (FPGA) implementation at a record 200-Gb/s throughput.
Journal ArticleDOI
Efficient Optical Millimeter-Wave Generation Using a Frequency-Tripling Fabry–Pérot Laser With Sideband Injection and Synchronization
TL;DR: In this article, a low-cost 40 GHz optical millimeter-wave (mm-wave) generation scheme constructed by the utilization of a frequency-tripling directly modulated Fabry-Perot (FP) laser is presented.
Journal ArticleDOI
Very-High-Throughput Coherent Ultradense WDM-PON Based on Nyquist-ISB Modulation
TL;DR: In this paper, the authors proposed a very high-throughput coherent ultradense wavelength division multiplexing passive optical network (UDWDM-PON) with its bandwidth efficiency enhanced using Nyquist-independent-sideband (N-ISB) modulation.
