Abstract: The following example outlines how one might set the LOP threshold in a photodiode receiver such that the assert level is equivalent to a bit error rate (BER) of 10-3. The assumptions are as follows: The extinction ratio (re) = 10 The optical input sensitivity is -31dBm. A typical PIN responsivity (p) = 0.85A/W. A typical preamplifier transimpedance gain = 6kΩ. Noise-limited input sensitivity.
