SEPTEMBER 10, 2009 -- RSoft Design Group has announced the release of Optical Communication Design Suite version 5.1, which includes OptSim and its multimode companion, ModeSYS. The new release includes new features to design and simulate next-generation systems such as 100-Gbps coherent PM-QPSK, interferometric fiber-optic gyroscope (I-FOG), bidirectional reflective semiconductor optical amplifier (RSOA)-based WDM-PON, burst-mode data transmission, and advanced electrical circuit modeling with embedded Spice engine.

OptSim 5.1 is particularly well suited to model 100G coherent PM-QPSK systems, RSoft says. The new release includes constant-modulus and training sequence based equalization algorithms, Viterbi-Viterbi phase estimation, electronic and optical dispersion compensation, DSP-based polarization recovery, Karhunen-Loeve (K-L) BER estimation, and direct error-counting up to and beyond a million bits.

The introduction of I-FOG modeling aids in the design of next-generation I-FOGs. The feature includes advanced physical-layer system simulation including Monte-Carlo method, power budget analysis, and flexible signal visualization capabilities, according to the vendor.

OptSim 5.1 also comes with an embedded Spice engine, enabling the co-simulation of Spice circuits. RSoft says the user can use the new Custom Component for Spice (CCS) model to implement any custom electrical circuit or use many existing Spice circuits widely available.

Meanwhile, the RSOA model can aid bi-directional PON deployments, while the burst-mode data transmission feature applies to PON systems that use this TDM technology.

RSoft adds that the new release also comes with a number of improvements and enhancements to the existing models and the graphical user interface. Moreover, a number of new application notes have been added to assist customers in the design and optimization of a variety of advanced applications.
