RSoft Design Group has released Optical Communication Design Suite v5.1, which includes OptSim and ModeSYS. The new release includes features to design and simulate next generation systems such as 100 Gbit/s coherent PM-QPSK, Interferometric Fiber-Optic Gyroscope (I-FOG), bidirectional RSOA-based WDM-PON, Burst Mode data transmission, and advanced electrical circuit modelling with embedded Spice engine.
OptSim 5.1 is the ideal environment to model 100G coherent PM-QPSK systems. The new release includes Constant-Modulus and Training Sequence-based equalisation algorithms, Viterbi-Viterbi phase estimation, electronic and optical dispersion compensation, DSP-based polarisation recovery, Karhunen-Loeve (K-L) BER estimation and direct error-counting up to and beyond a million bits. Another important feature in this new release is the introduction of Interferometric Fiber-Optic Gyroscope modelling. OptSim provides a comprehensive platform to design next-generation I-FOGs, featuring advanced physical-layer system simulation including Monte-Carlo method, power budget analysis, and flexible signal visualisation capabilities.
In addition, OptSim 5.1 comes with an embedded Spice engine, enabling the cosimulation of Spice circuits. Hence, 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. Other notable new features include the introduction of a Reflective Semiconductor Optical Amplifier (RSOA) model, which is vital in state-of-the-art bi-directional PON deployments, and Burst-mode data transmission in PON systems that use the Time-division multiplexing technology.
The new release also comes with a number of improvements and enhancements to the existing models and the Graphical User Interface (GUI). Moreover a number of new application notes have been added to assist customers in the design and optimisation of a variety of advanced applications.
