OptEM Engineering Inc.


Incorporated in 1992, OptEM Engineering Inc. is a privately owned engineering software and consulting services company specializing in the electromagnetic and signal integrity analysis of copper cables. The OptEM Cable Designer software reduces prototyping iterations and costs by allowing engineers to simulate the cable’s electrical performance prior to prototyping and lab measurements. Engineers can also perform what-if experiments to investigate cable anomalies and material effects in new and existing cable designs. Customers are located worldwide and support is conducted from OptEM's head office in Calgary, Canada, together with local distributors. ------------- OptEM Cable Designer – software used to design and model all types of copper cables in telecommunication and data transmission applications: • unshielded and shielded twisted-pair • quad • ribbon • subsea umbilical • specialty cables • flex circuits ------------- OptEM Cable Designer is the first software tool customized to design, analyze and model electrical and propagation parameters for all types of copper cables. The software reduces prototyping iterations and costs by allowing engineers to simulate cable performance prior to prototyping and lab measurements. Cable design details are entered through the graphical interface or by reading Excel spreadsheets. Built-in libraries of frequency-dependent materials and object definitions are used in cable construction and can be easily customized. Enhanced design features include Pair Advisor (calculates conductor and insulate diameters for a selected standard) and Lay Length Advisor (optimizes lay length values for data cables to minimize NEXT). The cable cross section is automatically extruded by the software producing a 3D cable model showing rotations, pair twisting, and customized insulation colors. OptEM Cable Designer’s built-in EM field solver analyzes high frequency skin and proximity effects in wires, eddy currents in shields, and dielectric losses in insulation. Including these effects is crucial for accurate analysis and modeling of copper cables. On output the software provides ASCII reports for LRCG parameters, and plots S-parameter data for RL, IL, NEXT, FEXT, ELFEXT, and PS-NEXT and PS-FEXT.
