detailed description

Hereinafter, embodiments of the present application will be described with reference to the drawings.

Figure 1 is a block diagram of the 10G EPON symmetric ONU. As shown in Figure 1, the 10G EPON symmetric mode inherits the 10G Ethernet technology, and the MAC interface is XGMII.

Figure 2 is a schematic diagram of the data relationship of the XGMII interface. As shown in Figure 2, according to the IEEE802.3 protocol, it is ensured that the Start control character is aligned with lane0.
