We demonstrate 12-core × 3-mode dense SDM transmission over 527 km graded-index multi-core few-mode fiber without mode-dispersion management. Employing low baud rate multi-carrier signal and frequency-domain equalization enables 33.2-ns DMD compensation with low computational complexity.
This paper evaluates the Q-factor improvement by maximum ratio combining for optical diversity transmission signals under the condition of the parametric process due to the Kerr effect and group-velocity dispersion.
We demonstrate 25-GHz-spaced eleven-channel 171 Gb/s PDM 16-QAM transmission over 1440 km. 16-QAM signals were generated by high-speed digital-to-analog converters. We achieved a record spectral efficiency-distance product of 9216 b/s/Hz-km (6.4 b/s/Hz × 1440 km) in the 16-QAM format.
The concatenation of LDPC and RS codes has been demonstrated using a real-time FPGA prototype. A net coding gain of 9.0dB for 31.3-Gb/s was achieved with 20.5% redundancy for an input BER of 10−2.
We have developed a 2-bit 32 Gsample/s soft decision LSI for low-density parity-check code FEC at 100 Gb/s in 0.13 mum SiGe-BiCMOS which generates confidence bit with 25 mVpp sensitivity.
We demonstrated 25-Gb/s (21.7-Gb/s after coding) single-carrier (SC) transmission with QPSK format over 240 km of SMF (4080 ps/nm) by employing frequency-domain equalization (FDE).
