CableExpert – Fast and Accurate Cable Modeling and Simulation

Background

Cable assembly is a key building component in network systems. Accurate modeling of cables is becoming a necessity to achieve the desired signal integrity with multi-gigabit data rate. Twinaxial cable used for SFP and QSFP interface in 10G/40G/100G Ethernet is such an example. Many parameters have significant impact on signal quality such as drain type and shielding pattern, to name a few. Engineers need a fast and accurate way to model and simulate the cable with high confidence in signal integrity.
