The 10G-EPON access architecture supports what upstream data rates?

The 10G-EPON (10 Gigabit Ethernet Passive Optical Network) access architecture is designed to provide high-speed data transmission over fiber-optic networks. In this architecture, the upstream data rates are significant because they dictate how data is sent from end-users back to the network.

The correct choice highlights that 10G-EPON supports upstream data rates of 1 Gbps and 10 Gbps. This is a key feature of 10G-EPON technology, which aims to cater to the increasing demand for higher bandwidth and faster internet services. The 1 Gbps upstream rate allows for a baseline level of performance suitable for various standard applications, while the 10 Gbps option provides a much higher capacity for demanding applications that require more bandwidth, such as video streaming, online gaming, and large file transfers.

Different choices provide alternate rates that do not align with the known specifications of 10G-EPON. For example, offerings such as 2 Mbps and 10 Mbps, or 5 Gbps and 10 Gbps, do not accurately reflect the capabilities of 10G-EPON. The architecture’s intent is not to cater to such lower or partial speeds in upstream data transmission, emphasizing why the
