PURPOSE:To provide the optical communication equipment and the optical communication system for efficiently transmitting signals. CONSTITUTION:When signal light 14 for reception is made incident to an optical element 10 while making excited light 11 from a laser light source 12 matching with the optical axis of at least one generated light 17, among two parametric generated beams 16 and 17, generated by irradiating the optical element 10, parametric amplification is performed, and two parametric amplified beams 26 and 27 provided with the information of signal light for reception are outputted in the same direction as the radiating direction of the parametric generated beams 16 and 17. Among these parametric amplified beams 26 and 27, a first parametric amplified beam 26 is applied to an optical detecting means 18 and information loaded on the first parametric amplified beam 26 is detected. On the other hand, a second parametric amplified light 27 is outputted as signal light for transmission. |
