Version 11.4 provides access to more than 900 ready-to-run simulation setups. We added over 20 new and improved demo examples to illustrate the application of the new features and modules.
This simulation setup demonstrates the transmission of 10 x 28 Gbaud DP-16-QAM channels in the C band over a 300 km repeaterless ultra-long system consisting of two fiber spans and a doped fiber amplifier placed between them.
The pump power of the remote gain unit remains nearly constant in the investigated range of transmitter power, thus allowing the usage of a system-level amplifier model.
The detailed design of the remotely pumped doped amplifier demonstrates a related setup.
