光纖收發器熱模擬及應用於電子設備系統設計開發之簡化熱模型方案

The demand for fiber optic transceivers in ultra-high-speed networks has kept increasing — the ultra-high-speed results in high power density in the optic transceivers. As laser diodes are sensitive to temperature, it is vital to provide a controlled thermal environment for the reliable operation of optic transceivers. Electronic equipment manufacturers need systematic design solutions to improve heat dissipation efficiency. Applying computational fluid dynamics (CFD) can help achieve the goals. However, for system-level thermal simulations, the cost of building detailed CFD models for optic transceivers is too high. Furthermore, the equipment manufacturers cannot obtain the correct thermal data required for modeling because the data is the fiber optic transceiver supplier’s know-how. Therefore, a feasible solution is for optical transceiver suppliers to provide simplified thermal models for the customers. This project draws the market and technology needs; in addition to establishing the thermal experiment and CFD thermal simulation capabilities, the primary goal is to develop a simplified thermal calculation model for fiber optic transceivers. We adopt the DELPHI method, which complies with JEDEC, the international electronic packaging industry specifications, to develop the compact thermal mode (CTM). The equipment manufacturers can use CTM, the simplified thermal model of fiber optic transceivers, to conduct system-level thermal management analysis and design for the data center equipment, such as servers and switches. This project assists domestic suppliers in breaking through the bottleneck of thermal management technology of optical fiber transceivers. It also improves the link between suppliers and customers, increasing the added value of products and competitiveness.
