DP-QDQ is a partial-response shaping modulation based on 16QAM, which has been proposed in our previous research paper. In this paper, the power spectral density (PSD) of the DP-QDQ signal is analyzed and compared with DP-16QAM, DP-64QAM, and DP-256QAM signals, and the simulation setup...

For the low-cardinality DP-QAM04 format the required security gap is mainly equal to the theoretically achievable minimum security gap. However, with increasing cardinality of the modulation format, the practical implementation penalty accounts for a significant portion of the security gap of up to ...
Experimental Investigation of Security Gaps when using Punctured LDPC Coding in Coherent Systems up to 64-GBd DP-64QAMIn optical transmission systems, security against eavesdroppers is of increasing importance. Following the concept of physical-layer security, we experimentally quantify the security gap ...
665 and 947b/s/Hz ultra-highly aggregate spectral-efficient SDM transmission over 9.8km 6-mode 19-core fibre has been successfully demonstrated using 5.7-GHz-spaced 5-Gbaud DP-16QAM/64QAM Nyquist WDM signals with pre-emphasis-based MDL compensation and cladding-pumped 6-mode pre-amplification....
