中文摘要 |
本論文係光纖通訊40Gb/s光收發模組的研製與量測,使用四個傳輸速率為10Gb/s的光收發模組來擴充通訊系統頻寬至40Gb/s。光收發模組包含光發射模組與光接收模組兩部分,光發射模組由雷射驅動IC及波長為1310nm的法布里-柏羅雷射光發射次組裝模組(TOSA)所組成;而光接收模組由限幅放大器與波長為1310nm檢光器(PIN-TIA)的光接收次組裝模組(ROSA)所組成。 在印刷電路板佈局中,除了適當地運用終端阻抗匹配設計和微帶線特性阻抗計算,且必須考慮被動元件與印刷電路板訊號連接之介面所產生的寄生效應、阻抗不連續,以及電源雜訊、串音現象等問題,來避免訊號產生失真劣化。 光收發模組量測結果,在訊號為231-1且傳輸速率為10Gb/s操作下,採用自發自收架構,以通道三之光發射模組光源搭配單通道光接收模組測得峰值抖動結果為34.2ps、上升時間為51ps、下降時間為39ps;以通道四之光發射模組光源搭配單通道光接收模組測得峰值抖動結果為38.4ps、上升時間為55.96ps、下降時間為40.5ps。並符合OC-192眼圖遮罩的規範,其眼圖餘裕分別可達到12%與14%。而在誤碼率(BER)為10-12條件下,接收端靈敏度為-2.7dBm。 |
Abstract |
The development and measurement of 40Gb/s optical transceiver module applied in optical-fiber communication is investigated. The module extends data rate by using four optical transceiver modules, with 10Gb/s for each throughput. The optical transceiver module consists of transmitter and receiver. The transmitters are composed by laser driver IC and 1310nm FP (Fabry-Perot) laser, and the receivers are composed by limiting amplifier and 1310nm ROSA (Receiver Optical Sub-Assembly). An optical transceiver module is operated at signal pattern of 231-1 and data rate of 10Gb/s. For back-to-back measurement, the optimum peak-peak jitter, rising time, and falling time are 34.2ps, 51ps, and 39ps, respectively. The result of eye diagram measurement can meet the mask of OC-192 standard, and the eye mask margin can also reach 14%. In the condition of bit error rate of 10-12, the sensitivity of receiver is -2.7dBm. The transceiver module can include DFB (distributed feedback) laser for application in the WDM (Wavelength Division Multiplexing) system. |
