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 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 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.
