Abstract: PURPOSE: An optical transmission system is provided to generate a duobinary optical signal without using an electrical low pass filter, and not to be influenced by a transmission characteristic for a PRBS(Pseudo Random Bit Sequence), thereby improving nonlinear and distributive characteristics. CONSTITUTION: A code conversion device converts an NRZ(None Return to Zero) signal into a duobinary signal, and outputs the converted duobinary signal.

A first attenuating part(318) and a second attenuating part(322) control attenuation of the amplified upward signal. A RF signal separating part(315) outputs the upward signal to an optical module and a detecting part(312). A peak detecting part measures an intensity value of the upward signal. An A/D converting part converts the measured voltage value into a digital value.
