Performance of DSP-assisted gray-coded DP-16-QAM Nyquist-DWDM super-channel transceiver for high-speed long-haul optical interconnects

In this paper, a 64-channel Nyquist-DWDM system has been proposed for spectral-efficient long-haul optical interconnects. Dual-polarization 16-QAM has been used at each transmitter, and the homodyne detection technique decodes the transmitted …

A vectored fragmentation metric for elastic optical networks

When circuits are set up and dismantled dynamically in elastic optical networks, the link spectrum becomes fragmented. The fragmentation limits the available path choices and may lead to significant blocking of connection requests. The …
