Optical duo-binary transmission apparatus using polarization modulator |
摘要 |
An optical duo-binary transmission apparatus using a duo-binary modulation method is disclosed. The optical duo-binary transmission apparatus using a polarization modulator includes a precoder for coding an inputted binary data signal; a low-pass filter for converting the coded binary data signal into a three-level signal by restricting a bandwidth of the coded binary data signal; a light source for generating light; a polarization modulator for modulating a polarization of the light outputted from the light source according to the three-level signal; and a polarizer for transmitting only an optical signal having a predetermined directionality from among polarization-modulated optical signals.
