摘要：

The utility model relates to an optical fiber connection device which is arranged between a computer and various sonic devices. The electromagnetic interference of the inside of a computer case is effectively avoided, and the quality of the computer when sound is played is enhanced. The entire system has a good anti-electromagnetic radiation effect. The rear end of a digital audio output interface of a host computer is provided with an electricity / light converting circuit, and a light / electricity converting circuit of an input interface of the sonic device is orderly connected with a decoder (selectable), a digital / analogue conversion circuit and an amplifying output. One end of an optical fiber line is connected with an electricity / optical converting circuit, and the other end of the optical fiber line is connected with an optical / electricity converting circuit. The sonic device receives optical signals through the optical fiber line, and conducts light / electricity conversion and digital / analogue conversion. Sound signals are decoded, and are enlarged.
