What is Ethernet (fast) in terms of data rate?

Ethernet (fast) refers to the IEEE 802.3 standards providing 100 megabits per second nominal rate, commonly using twisted-pair copper or fiber links for local area networks.

What does OC3 represent in networking?

OC3 is a SONET optical transmission level with a rate of 155.52 megabits per second, used for synchronous optical networking over long distances and backbone connections.

Why convert from Ethernet (fast) to OC3?

Converting helps integrate 100 Mbps local area network rates with higher-speed fiber optic backbone systems and assists in network capacity planning and compatibility.

Does this conversion consider physical medium differences?

No, the conversion assumes synchronized data rates but does not take into account differences between copper Ethernet and fiber-based SONET interfaces.
