摘要

在高能物理實驗中，數據傳輸系統必須在嚴酷輻射環境，強磁場，大量的每束交叉相互作用，以及探測器前端與後端電子設備之間的距離較長的情況下運行。由於這些原因，有必要開發客製化的高速耐輻射數據收發器。本文介紹了雙通道微型光發射器（MTx），收發器（MTRx）和小封裝可插拔發射器（MTx-SFP）的設計，質量分析和老化試驗。收發器包含雷射驅動器（LOCld）和850 nm 多模垂直共振腔面射型雷射（VCSEL）。所有模組，包括3240 個MTx，810 個 MTRx 和600 個 MTx-SFP，在生產過程中均已通過5.12 Gbps眼圖測試，以此進行質量控制。MTx 和MTRx 的成品率高達4650 個模組總數的98％。對24 個光學收發器 (MTx)進行了6000 小時的老化試驗並定期測試位元錯誤率和眼圖。

In high energy physics experiments the data transmission system has to operate in a harsh radiation environment, strong magnetic fields, large number of interactions per bunch crossing, and a long distance between the on-detector front-end and the back-end electronics. For these reasons, high-speed radiation tolerance customized data transceivers must be developed. This thesis presents the design, quality analysis, and ageing tests for the dual-channel miniature optical transmitter (MTx), transceiver (MTRx), and the transmitter packaged in small form-factor pluggable format (MTx-SFP). The transceivers contain the link-on-chip laser driver (LOCld) and the multimode 850 nm vertical-cavity surface-emitting laser (VCSEL). All modules, including 3240 MTx, 810 MTRx and 600 MTx-SFP, have been tested for quality control during production using eye-diagram tests at 5.12 Gbps. The yield rates of MTx and MTRx were found to be as high as 98% for a total of 4650 modules. 24 transmitter modules have been monitored by testing the bit-error rate and using eye-diagram test periodically, over 6000 hours of burn-in.
