Notes
(1) The fiber coupling light output set at –14.5 dBm or –24.0 dBm.
(2) Rsi, Rso: Standard load resistor (Rsi: 3.3 kΩ, Rso: 2.2 kΩ)
(3) Set the oscilloscope to the storage mode and write time to 3 seconds.
Do not allow the brightness to be increased too much. The waveform would be distorted.
(4) VCC = 3.0 V (State of operating)
(5) The probe for the oscilloscope must be more than 1 MΩ and less than 10 pF.
