*① REF-1650-XX-XX, where the first XX refers to the optical fibre type and the second XX refers to the structure type
*② Insertion Loss (dB) = - 10lg (Output Power/ Input Power) (dB)
*③ Return Loss (dB) = -10lg (Reflected Power/ Input Power) (dB); To measure the Return Loss of reflect band, the light of 1650nm should be injected from the female side of reflector.
