Description

Optical Network System Trainer

Features

The system conduct the WDM transmitting & receiving test, based on such
built-in functions as Function Generator, Dual Light Source (1310/1550nm),
Dual Optical Receiver (power meter), and Digital Oscilloscope.
The system conduct optical communication practice and operation test by use
of a light source with various wavelengths. (650nm-MM, 1310nm-SM, 1550nm-SM, etc.)
It possible to make a test on physical properties of light-using equipment. (e.g.
total reflection principle, refraction & reflection property, loss property etc.)
The system measure Optical Coupler, Attenuator (SdB, 10dB), WDM (Mux & Demux).
Is also offer performance tests on different kinds of optical application devices provided.
Digital control of all input/output data by use of FPGA. (e.g., LCD control, Signal Input/Output Selection, etc.)
It control PC software through private digital devices (Digital Potentiometer,
8-channel, 12-bit Serial DAC, etc.) and programs: Selection Function, LCD
Display, Amplitude, Frequency, LD Bias Current, etc.
It inputs various user-designating data signals beside outputting built-in
functions (i.e., selection of eight signals – Sign, Triangle, Square, Ext Dig, Ext Anal.
The system use private 8-channel, 12-bit ADC (Analog Digital Converter) to
improve the accuracy of LCD output data in the equipment.
The system should use private high-speed/high-dynamic range ADC for
parallel transmission of input/output data. (12-bit, 1-channel, 20MSPS, High SNR-69dB, etc.)
The system can make a PC output of every output waveform in equipment It has a built-in digital oscilloscope function
