Acreo Uses AWR Visual System Simulator to Optimize Performance of 100-Gb/s Optical Transceiver
March 4, 2010
Acreo AB, a Swedish company that provides contract R&D and production resources for innovative products in electronics, optics, and communication technology, needed to create a single-carrier-modulation (SCM) transceiver link suitable for 100-Gb/s transmission. System-level development of the SCM transceiver link was modeled within AWR's Visual System Simulator™, which allowed Acreo to assess the influence of component performance in the electrical domain, particularly in respect to non-linearities and noise. The design of component building blocks such as IQ modulators, power combiners, and low-noise amplifiers in the 65-nm CMOS silicon-on-insulator process was performed at the circuit level. Component performance was then assessed in the VSS software to investigate the suitability of CMOS for next-generation optical networking within the transceiver's architecture.
"Using VSS software together with MATLAB® to create the RF system model proved to be straightforward," said Lars Pettersson, research engineer at Acreo, "and it's flexibility, ease-of-use, and open platform were very positive features. We gained a thorough understanding of how group delay variations affect performance and were able to optimize the system using this knowledge."
