(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 GP1FB201RK are not fixed constantly when it receives

the modulating light (including DC light, no input light) less than 0.1Mbps.
