Notes ( 1) VCC = 3.0 ± 0.05V ( State of operating)
( 2) The fiber coupling light output set at - 14.5dBm/ - 24.0dBm.
( 3) The probe for the oscilloscope must be more than 1MΩ and less than 10pF.
( 4) The output (H/L level) of GP1F361R are not fixed constantly
when it receivers the disturbing light ( including DC light, no input light) less than 0.1Mbps.
