Note 1 ) The waveform write time shall be 4 seconds. But do
not allow the waveform to be distorted by increasing
the brightness too much.
2 ) VCC = 5.0 ±0.05V (Operating )
3 ) The probe for the oscilloscope must be more than
1MΩ and less than 10pF.

attenuator
Note 1) Optical power meter must be calibrated to have
the wavelength sensitivity of 660nm.
2) With no optical attenuator connected, use the
transmitter GP1F31T/GP1F32T/GP1F33TT and
the optical fiber cable GP1C331 with the fiber
coupling light output set at - 15dBm/ - 24dBm.
