Optical interconnection system for transmitting and receiving a three-level signal and method of operating the same

Abstract

Provided is an optical interconnection system that transmits and receives a three-level signal. The optical interconnection system includes a first and a second optical interconnection device that transmits and receives a two-level signal, and a synthesizer that outputs a three-level signal by synthesizing signals from the first and second optical interconnection devices. The optical interconnection system may transmit and receive a three-level signal while using an optical interconnection device that interconnects a two-level signal.

1 . An optical interconnection system that transmits and receives a three-level signal, comprising:
 a first optical interconnection device and a second optical interconnection device, each of the first and second optical interconnection devices transmitting and receiving a two-level signal; and   a synthesizer that outputs a three-level signal by synthesizing signals received from the first and second optical interconnection devices.
