Optical Communication Design Suite version 4.7

RSoft Design has released Optical Communication Design Suite version 4.7, which includes OptSim and its multimode companion ModeSys. The new release includes a new DFE/FFE EDC model with MMSE criterion coefficient optimisation and advanced D(Q)PSK models for bitrates up to 100 Gbit/s and beyond.

With this new DFE EDC with automatic coefficient optimisation model, OptSim becomes the ideal framework to design and simulate multimode and single-mode systems deploying EDC at the receiver, based on standards such as 10GBASE-LRM and ITU G.959.1. The model enables OptSim 4.7 users to specify many options including the number of feed-forward and feedback taps.

When the number of feedback taps is equal to zero, the model degenerates into a FFE EDC. The coefficients can also be manually inserted so that the user can perturb their optimal value to study the system resilience to sub-optimal EDC.

OptSim 4.7 has several capabilities that can be used to further investigate D(Q)PSK system design, including new transmitters, receivers and BER models, as well as its accurate nonlinear fibre model.

Other notable highlights within OptSim 4.7 include the new Liekki Application Designer interface for device-level fibre laser/amplifier simulation inside a system simulation, updated Jones Matrix Transfer Function model to support latest Luna Technology's measurement files, and a new Compact Transient EDFA model. Other graphical user interface and framework enhancements include a new application gallery for conveniently organising built-in examples and user-designed project files, direct access to application notes from project layout, and an enhanced project archiving wizard.
