Abstract
A colorless optical transceiver and an optical communication system including the same are disclosed herein. A controlling unit of the colorless optical transceiver forms a control current based on intensity of an external-injection light provided from an external light source. A light source driving unit coupled to the controlling unit forms a driving current based on the control current. An internal light source is coupled to the light source driving unit, the internal light source being configured to receive the external-injection light and the driving current and to convert the driving current into a colorless sending light, wherein a wavelength of the colorless sending light is locked by that of the external-injection light. The light output from the internal light source is controlled based on intensity of external-injection light calculated by using optical loss, which varies according to the distances between optical devices and connection state. Thus, the light output from the colorless optical transceiver and the extinction ratio may be stabilized.
