Santec扫频测试系统通过实时记录可以同时获取可调激光器的输出功率与经过DUT的传输功率,从而准确计算出WDL/PDL的数据。采用Mueller矩阵生成快速的PDL测量方案。
此系统也可简化为使用Santec 数据采集模块(SPU-100)搭配其他光学的功率计或探测器,可广泛用于WDL测试。
通过采样和缩放算法在保持测试方案完整性上可以保持测试性能输出。
另外,该系统尤其适用于DWDM和高Q光子器件光谱特性的测试。通过快速扫描和准确测量可有效节省时间,以确保测试设备的完整性和有效性。

扫频测试系统波长相关损失 (Wavelength Dependent Loss)测量
1.测量动态范围-可测量80dB以上的高动态范围
Santec可调谐激光器TSL系列,可降低ASE光噪音、实现了90dB/0.1nm以上*信噪比的同时,可维持+10dBm以上的高功率的输出。高密度波分复用(DWDM)器件和WSS(Wavelength Selective Switch )等在新一代器件评价中发挥其威力。以下是以各自带通滤波器(CWDM滤波器)和噪音滤波器(FBG)的测量数据。
2.测量的波长精度 +/-3pm
Santec可调谐激光器TSL系列,配备了高性能的波长检测器可进行波长精度的测量。Acetylene(12C2H2)气体分子作为波长参考
3. 测量宽波长分辨率 <0.1pm
在该扫描测试系统不仅可以测量为测量光学器件(包括密集波分复用(DWDM)器件、波长选择开关 (WSS)等),根据波长扫描分辨率可对滤波器(High Q腔装置)进行高效的测量。
