Abstract
A system, a non-transitory computer readable media and a method for intra data center optical communication, the method may include (a) receiving an optical input signal by a coherent optical receiver of a second unit of a data center; wherein each input optical signal represents a transmitted optical signal that was transmitted by a coherent transmitter of a first unit of the data center; wherein the transmitted optical signal is generated by modulating a transmitter laser signal that is outputted from a laser of the coherent transmitter; (b) generating, by a controllable laser of the coherent optical receiver, a reference signal; wherein a frequency of the reference signal is controlled by a processor of the coherent optical receiver; and (c) recovering data embedded in the optical input signal; wherein the recovering of the data comprises optically processing the reference signal and the optical input signal.
