IMD3 = −90 dBc MAX.
•
Optical return loss 45 dB
•
High quantum efficiency
•
Small dark current ID = 0.1 nA
η
= 81 % @ λ = 1 300 nm•Coaxial module with singlemode fiber (SM-9/125)
•
Small capacitance Ct = 0.7 pF
•
Low operating voltage VR = 10 V
•
Detecting area size
•
NDL5481P1 and NDL5481P2 have a flange.
