0.05dB衰減,0.001dB分辨率 
0.02dB p-p偏振靈敏度 
可選的輸出 
后向反射器模式
8156A是單模和多模應用的一種衰減器。

可以選擇所希望的回波損耗性能（可達60dB）。可選的13dB監測輸出使您可以測量該衰減器輸出處的入號功率。利用共內置后向反射器模式和一個外部參考反射器（81000BR），8156A可被用作一個可編程后向反射器，以測量元件和系統對反射的靈敏度。

衰減范圍在1250nm和1650nm之間是60dB，具有0.001dB的分辨率。新穎的單濾波器設計使儀表無須進行距離調整。從而消除暗點或潛在的衰減過沖或下沖。典型的衰減±0.05dB,同時偏振靈敏度小于0.02dB p-p。
