Note 4
Notes:
1. For IFPK > 80 mA, the duty factor must be such as to keep IFdc ≤80 mA. In addition, for IFPK > 80 mA, the following rules for pulse width apply:
IFPK ≤160 mA: Pulse width ≤1 ms
IFPK > 160 mA: Pulse width ≤1 S, period ≥20 S.
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 IFPK > 80 mA will cause increased link tPLH propagation delay time. This extended tPLH time contributes to increased
pulse width distortion of the receiver output signal.
