Use of Simulation Technology for Solving Design Challenges of 10Gbps Pluggable Optical Transceivers

摘要

Since thermal dissipation and electromagnetic radiation are complicated phenomena, they are considered as practical engineering problems in designing pluggable optical transceivers. In actual development, intuitive or experience-based approaches may be considered good enough since these problems can be easily solved with patches even when cause-effect relations are unknown. However, an analytical and theoretical methodology, which is used to make predictive analyses on countermeasures to problems, can avoid trial and error procedures. If the problem is complicated, the combination of CAE analysis and experiment is always thought to be the best choice. In this paper, the authors describe how to deal with problems through the practical case study of the actual 10-Gigabit/s optical transceiver development. The biggest challenge in the development of this transceiver, which is of a small size for its amount of heat dissipation, is how to manage heat conduction and to minimize the leakage of electromagnetic noise. In this paper the authors proposed the basic direction for the design improvement utilizing CAE technology and experiment and showed the correlation with the results obtained.
