簡要描述:
掃頻測試系統結合Santec的TSL系列可調諧激光器與該光功率計(MPM-210或MPM-200)、數據模塊(PCU-100)和自定義軟件相組合,完整的掃描測試系統優化WDL和PDL測量用于研發和生產環境。
Santec掃頻測試系統通過實時記錄可以同時獲取可調激光器的輸出功率與經過DUT的傳輸功率,從而準確計算出WDL/PDL的數據。采用Mueller矩陣生成快速的PDL測量方案。
此系統也可簡化為使用Santec 數據采集模塊(SPU-100)搭配其他光學的功率計或探測器,可廣泛用于WDL測試。
通過采樣和縮放算法在保持測試方案完整性上可以保持測試性能輸出。
另外,該系統尤其適用于DWDM和高Q光子器件光譜特性的測試。通過快速掃描和準確測量可有效節省時間,以確保測試設備的完整性和有效性。

掃頻測試系統波長相關損失 (Wavelength Dependent Loss)測量
1.測量動態范圍-可測量80dB以上的高動態范圍
Santec可調諧激光器TSL系列,可降低ASE光噪音、實現了90dB/0.1nm以上*信噪比的同時,可維持+10dBm以上的高功率的輸出。高密度波分復用(DWDM)器件和WSS(Wavelength Selective Switch )等在新一代器件評價中發揮其威力。以下是以各自帶通濾波器(CWDM濾波器)和噪音濾波器(FBG)的測量數據。
2.測量的波長精度 +/-3pm
Santec可調諧激光器TSL系列,配備了高性能的波長檢測器可進行波長精度的測量。Acetylene(12C2H2)氣體分子作為波長參考
3. 測量寬波長分辨率 <0.1pm
在該掃描測試系統不僅可以測量為測量光學器件(包括密集波分復用(DWDM)器件、波長選擇開關 (WSS)等),根據波長掃描分辨率可對濾波器(High Q腔裝置)進行高效的測量。
