Notes:
1. PWSFH_output = PWopt_input + (tPLH – tPHL); PW = pulse width
2. Switching times increase with temperature
3. Measured with recommended Rpullup = 330Ω (see Figure 1)
4. Sensitivity increase with temperature
5. ValuedBm=10*log(Valuemeasured / 1mW)
6. Limits valid for optical input power from -20dBm(mean) to -9dBm(mean)
7. dBm(peak) = dBm(mean) + 3dB
