由於光通訊提供長距離且高頻寬的特性,大幅改變了人類的生活品質。本論文中主要討論高速光收發機研製,在發射端的選擇為一雷射驅動積體電路(Integrated Circuit,IC)和1310nm法布里-珀羅雷射光次積組(Fabry-Perot Laser Optical Sub-Assembly,FP-LASER OSA)構成,接收端為一限幅放大器IC和PIN光二極體+轉阻放大器(PIN+TransImpedance Amplifier) OSA組成,基底部分則使用FR4的板材。
由於傳輸速率不斷提昇,傳統的佈線(layout)方法可能會使高速傳輸的電路產生反射及一些雜訊等問題。在高速信號傳輸下對於微帶線的設計和印刷電路板(Printed Circuit Board,PCB)的佈局顯得格外重要,經由正確選擇工作點和PCB佈局來發揮IC的最佳特性及穩定性,在必要時也需加上一些補償措施來達到較佳的結果。
Due to its high-bandwidth and long-range characteristics, optical communication plays an important part in our daily lives and improves the quality of lives for humans. In this thesis,we decomposed the implementation of the optical transceiver circuits into two parts,the transmitter part and the receiver part. The transmitter includes a driver and a 1310nm FP Laser OSA(Fabry-Perot ooptical Sub-Assembly),the other part,the receiver,composed of a limiting amplifier and a PIN+TIA (PIN+TransImpedance Amplifier)OSA. The substrate for the transceiver is made of FR4.
The need for speed is growing very vastly,traditional layout with less concern to the length constraint 、rules and so on may give rise to reflection and some other noise problems in high speed circuits. At high speed transmission,microstrip line design and component placing on PCB(Printed Circuit Board) are important. With properly selecting biased point and enforcing correct PCB design,the best performance of IC on 2-layer PCB can be achieved,and several compensation if it is needed.
