Kecekapan spektrum rangkaian fotonik boleh dipertingkatkan dengan penggunaan perintah modulasi yang lebih tinggi dan jalur lebar saluran yang lebih sempit. Malangnya, penyelesaian ini dihalang oleh margin yang diperlukan untuk mengimbangi ketidakpastian dalam prestasi sistem. Tambahan pula, seperti yang diketengahkan baru-baru ini, pengasingan sistem pengangkutan optik meningkatkan margin yang diperlukan. Kami mencadangkan di sini rangkaian yang sangat cekap spektrumnya, yang marginnya diminimumkan oleh penugasan modulasi-pesanan/lebar jalur-jalur adaptif kualiti penghantaran yang didayakan oleh pemantauan prestasi optik (OPM). Keberkesanan mereka disahkan oleh eksperimen pada isyarat anjakan fasa kuadratur dwi-polarisasi 400-Gbps (DP-QPSK) dan modulasi amplitud kuadratur 16-ary (DP-16QAM) dengan aplikasi OPM berasaskan faktor Q yang dibangunkan baru-baru ini. Isyarat 32-Gbaud DP-QPSK empat subcarrier dalam 150/162.5/175GHz dan dua subcarrier 32-Gbaud DP-16QAM isyarat dalam 75/87.5/100GHz dianalisis secara eksperimen. Simulasi rangkaian berangka bersempena dengan keputusan eksperimen menunjukkan bahawa skim yang dicadangkan boleh meningkatkan kecekapan spektrum rangkaian secara drastik.

Abstract: The spectral efficiency of photonic networks can be enhanced by the use of higher modulation orders and narrower channel bandwidth. Unfortunately, these solutions are precluded by the margins required to offset uncertainties in system performance. Furthermore, as recently highlighted, the disaggregation of optical transport systems increases the required margin. We propose here highly spectrally efficient networks, whose margins are minimized by transmission-quality-aware adaptive modulation-order/channel-bandwidth assignment enabled by optical performance monitoring (OPM). Their effectiveness is confirmed by experiments on 400-Gbps dual-polarization quadrature phase shift keying (DP-QPSK) and 16-ary quadrature amplitude modulation (DP-16QAM) signals with the application of recently developed Q-factor-based OPM. Four-subcarrier 32-Gbaud DP-QPSK signals within 150/162.5/175GHz and two-subcarrier 32-Gbaud DP-16QAM signals within 75/87.5/100GHz are experimentally analyzed. Numerical network simulations in conjunction with the experimental results demonstrate that the proposed scheme can drastically improve network spectral efficiency.
