Notes:
1. 1.6 mm below seating plane.
2. It is essential that a bypass capacitor 0.01 µF be connected from pin 2 to pin 3 of the receiver. Total lead length between both ends
of the capacitor and the pins should not exceed 20 mm.

Notes:
1. Optical flux, P (dBm) = 10 Log [P (µW)/1000 µW].
2. Measured at the end of the fiber optic cable with large area detector.
3. R is open.

4. Pulsed LED operation at I > 80 mA will cause increased link t
propagation delay time. This extended t
time contributes to
