For a 10G-EPON architecture with a downstream speed of 10 Gbps, what two upstream rates are supported?

In a 10G-EPON (Ethernet Passive Optical Network) architecture, the downstream speed of 10 Gbps is complemented by specific upstream rates that facilitate bidirectional communication between the Optical Line Terminal (OLT) and the Optical Network Units (ONUs).

In this context, the correct pair of supported upstream rates corresponds to common standards in EPON technology. 10G-EPON can support upstream data rates of both 1 Gbps and 10 Gbps. The 1 Gbps upstream rate allows for compatibility with existing GPON (Gigabit Passive Optical Network) systems, while the 10 Gbps upstream rate maximizes capacity, enabling higher bandwidth applications and more efficient use of network resources.

The combination of these two rates provides flexibility and scalability, making it suitable for environments with varying bandwidth demands. Higher upstream rates, in particular, are vital in supporting applications that require rapid data transmission, such as video conferencing, large file transfers, and other high-bandwidth services.

This understanding of upstream capabilities underlines the technological advancements inherent in 10G-EPON systems, showcasing its ability to meet diverse network requirements effectively.
