      I designed a circuit with the photodiode centered at maximum power and noticed the values of the quality factor sometimes increased and at other times it decreased with increase in data rate and the value of the electrical power and BER varied. When the photodiode was not centered at maximum power, the quality factor decreased at high data rates but the BER was zero and the electrical power was constant. Please what does the photodiode centered at maximum power mean? What is the implication/function in the circuit design? I have attached my circuit design. I look forward to hearing from you thank you.

      Dear Buki,
      please refer to the datasheet for more explanation. Meanwhile, the Centered at max power determines whether the detector internal filter will be centered at the maximum amplitude of the signal or if it will be user-defined. It is recommended to be at your signal optical frequency/wavelength.
