Notes:
1. For I_FPK > 80 mA, the duty factor must be such as to keep I_Fdc ≤80 mA. In addition, for I_FPK > 80 mA, the following rules for pulse width apply:
I_FPK ≤160 mA: Pulse width ≤1 ms
I_FPK > 160 mA: Pulse width ≤1 µS, period ≥20 µS.
2. The propagation delay for one meter of cable is typically 5 ns.
3. Estimated typical link life expectancy at 40°C exceeds 10 years at 60 mA.
4. Pulsed LED operation at I_FPK > 80 mA will cause increased link t_PLH propagation delay time. This extended t_PLH time contributes to increased
pulse width distortion of the receiver output signal.
