∗12 Dissipation current measuring method

Optical power meter must be calibrated to have

the wavelength sensitivity of 660nm.

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.

The waveform write time shall be 4 seconds. But do

not allow the waveform to be distorted by increasing

the brightness too much.

The probe for the oscilloscope must be more than

1M

Ω and less than 10pF.
