Note 4
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

1 ms

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.
