Optical Oscilloscope
C8188
Virtually no waveform distortion
The Sampling Optical Oscilloscope performs all tasks from
light detection to signal processing, eliminating virtually all
the waveform distortions that occur in conventional methods
involving high-speed optical detectors and oscilloscopes,
such as those caused by reflection or ringing.
Wide bandwidth (20 GHz)
The C8188-01 and C8188-11 have a response
characteristic of 20 ps or less and a wide bandwidth
of 20 GHz or more.
Large detection area
The C8188-03 collects the entire signal from large aperture
sources such as a 1 mm POF for a highly accurate
measurement with a bandwidth of 2 GHz or more.
Easy operation
No need to consider matching conditions such as
impedance, which are necessary in conventional methods.
Control from PC
The Sampling Optical Oscilloscope is controlled from a PC
with a Windows environment to allow easy data storage
and connection to a LAN.

Application
Examples
This system measures high-speed pulse waveforms of
semiconductor lasers. A trigger signal is received from the
driver circuit of a semiconductor laser to measure the light of
the laser.
This system measures the transmission characteristics of POF.
It consists of the large detection area model C8188-03, the
picosecond light pulser PLP-02, and the all mode exciter
A8684. All mode light is generated using the PLP-02 and
A8684.
The bandwidth characteristics of a POF can be efficiently
analyzed by the Fast Fourier Transform (FFT) operation,
because all luminous flux of the output light from the POF is
detected with the C8188-03.

The picosecond light pulser PLP-02 is an ultra-short pulsed light source that utilizes a laser diode
(LD) head. It consists of a controller and an LD head. A number of LD heads are available to
accommodate various wavelengths, enabling optical output over a broad wavelength range of 405
to 1,550 nm.
The PLP-02 is optimal for frequency characteristic evaluation of POF optical communications and
Gigabit Ethernet fiber, and for response characteristic evaluation of a photodetector device.
