為了實現高速且低成本的光纖通訊系統，需要發展低成本的光收發模組。罐型封裝光模組有成本低、體積小、製程簡單與適合大量生產等優點。本文利用三維電磁模擬軟體，分析低成本的罐型封裝基座的高頻特性，並使用特製K型接頭，實驗量測罐型封裝基座的S參數與眼圖，證實TO-46罐型封裝基座的操作速率可達25 Gb/s。本文也製作25 Gb/s的TO-46罐型封裝垂直共振腔面射型雷射模組，以應用於高速光纖數據傳輸。

For high-speed and low-cost optical fiber communication systems, development of low-cost optical transceiver modules is necessary. TO-Can packaged optical modules have the advantages of low cost, compact size, and simple assembly process for mass production. In this paper, the high frequency characteristics of a TO-Can header were simulated through a three dimensional full wave electromagnetic simulator. The S-parameters and eye diagrams of a TO-Can header also were measured using our special K type adaptors. It has been verified that the TO-46 header can be operated at 25 Gb/s. The 25 Gb/s TO-46 vertical cavity surface emitting laser (VCSEL) module has been also fabricated. The 25 Gb/s TO-46 VCSEL module is potential to be applied in high-speed optical data-link networks.
