Agilent Technologies Inc. introduced a physics-based model for its opto model library that quickly and accurately solves the challenges posed by signal distortion in vertical cavity surface emitting lasers (VCSELs) used in rack-to-rack opto links. The new VCSEL model, available in the Advanced Design System 2013 Transient Convolution Element and SystemVue 2013 AMI Modeling Kit, is used both for modeling optoelectronic components and designing them into equipment.
With the VCSEL model, SystemVue 2013 now offers model builders, such as optoelectronic component vendors, a tool that supports the evolution of IBIS and can build rack-to-rack opto link models. The models run in ADS, the tool that opto component consumers (data center and telecoms equipment manufacturers, for example) use to design these subsystems into their larger systems. SystemVue 2013 also now features an enhanced model for the clock/data recovery circuitry found in both optical and electrical retimers.
