Abstract
To improve transmission characteristics of a CS-RZ signal, a laser diode (LD) (12) outputs a continuous light (CW light) having a wavelength .lambda.s (frequency f0). A CS-RZ pulse train shaper (14) generates a CS-RZ optical pulse train at a bit rate (B) from the CW output light from the LD (12). A data modulator (16) intensity-modulates an output optical pulse train from the shaper (14) according to a data (D) to be transmitted. An optical bandpass filter (18) passes through all of a component of carrier frequency (f0) and a component of frequency f1 (=f0+B/2) and transmits a small amount of component of frequency f2 (=f0-B/2).
