1. An optical communication system, comprising:
a hub optical transceiver configured for receiving a spectrum of wavelengths, wherein the spectrum of wavelengths includes a plurality of subcarriers, wherein each of the plurality of subcarriers includes a corresponding and unique band of wavelengths taken from the spectrum of wavelengths;
a power splitter coupled to the hub optical transceiver and configured to receive the spectrum of wavelengths, wherein the power splitter is configured to generate one or more replicated spectrum of wavelengths;
a top-of-rack switch coupled to the power splitter and deployed within a rack assembly servicing a plurality of servers, wherein the top-of-rack switch is configured to receive a replicated spectrum of wavelengths; and
a control system coupled to the top-of-rack switch, wherein the control system is configured to tune the top-of-rack switch to select one or more bands of wavelengths taken from the replicated spectrum of wavelengths.
