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.

Variable optical

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.
