Titel
Mixed bitrate and modulation format upgrades of non-slope matched submarine links
Abstract
New channels at higher titrates using RZ-DPSK modulation are added to Nx10.7-Gbit/s-ASK signals operating over transoceanic distances. Experiments and simulations are used to analyse performance and limitations, with 20-Gbit/s-RZ-DPSK being a strong candidate for upgrades.
