NCF device assembly, distributed networking system, and data transmission method

A network cloud fabric (NCF) device assembly, comprising:

• a first NCF device, comprising a first chip and a plurality of first NCF ports, wherein the first chip is electrically communicatively connected to at least one of the plurality of first NCF ports;
• a second NCF device, comprising a second chip and a plurality of second NCF ports, wherein the second chip is electrically communicatively connected to at least one of the plurality of second NCF ports;
• and
• a reconstruction component optical cross-connect device, comprising a plurality of receiving ports and a plurality of reconstruction ports, wherein the plurality of receiving ports are communicatively connected to the first chip and the second chip respectively through at least one of the plurality of first NCF ports and at least one of the plurality of second NCF ports, wherein
• each of the plurality of reconstruction ports is optically communicatively connected to at least two of the plurality of receiving ports in the reconstruction component optical cross-connect device, so that each of the plurality of reconstruction ports is communicatively connected to the first chip and the second chip, and the first NCF device further comprises a third chip, every n signal lanes in the first chip and the third chip constitute one of the plurality of first NCF ports, and n/2 lanes of one of the reconstruction ports the reconstruction port are respectively connected in a correspondence to one lane in the first chip or the third chip in the first NCF device, wherein n is a power of 2 and is greater than 0.
