ABSTRACT:
An optical transmission apparatus has an electro-optic converter device which converts an electrical signal into an intensity-modulated light signal in such a way that the amount of wavelength chirping is less than a given amount. Therefore a first optical fiber transmission path can convey the signal over a long distance with a small amount of waveform distortion. An optical property change device changes an optical property of the light signal sent from the first optical fiber transmission path. Therefore a second optical fiber transmission path can transmit the changed light signal to demanders' opto-electronic converter device while alleviating waveform distortion due to interference of plural light waves. The light signal is reconverted into an electrical signal.
