Subcarrier based data center network architecture

A system, comprising:

• a Tier 1 switch that supplies a plurality of data channels;
• a first transceiver that receives the plurality of data channels, the transceiver including a first transmitter, the first transmitter including:
• a laser, and
• an optical modulator that receives a plurality of radio frequency (RF) signals associated with the plurality of data channels, such that the optical modulator supplies a plurality of optical subcarriers based on the plurality of data channels;
• an optical platform, including one of an optical demultiplexer or a splitter, that receives the plurality of optical subcarriers, the optical platform having a plurality of outputs, each of which supplying at least one of the plurality of subcarriers;
• a plurality of second transceivers, each of which including a respective one of a plurality of receivers, each of which being coupled to a respective one of the plurality of outputs of the optical platform, each of the plurality of receivers receiving one or more of the plurality of optical subcarriers and supplying one or more of the plurality of data channels based on the received one or more of the plurality subcarriers;
• a plurality of servers, each of which receiving one or more of the plurality of data channels from one or more of the plurality of receivers;
• each of the plurality of second transceivers including a respective one of a plurality of second transmitters, each of which being coupled to a respective one of the plurality of servers, each of the plurality of second transmitters providing a respective one of a plurality of Nyquist subcarriers, such that each of the plurality of Nyquist subcarriers do not spectrally overlap with one another;
• and
• an optical combiner operable to combine the plurality of Nyquist subcarriers onto an optical fiber, which directs the plurality of Nyquist subcarriers to the Tier 1 switch.
