What does converting Ethernet (fast) to STS48 (signal) mean?

It means calculating how many STS48 signals are equivalent to a certain number of 100 Mbps Ethernet channels, useful for aggregating and transporting Ethernet traffic over SONET networks.

Can Ethernet (fast) be directly converted to STS48 signal without additional equipment?

No, direct conversion requires multiplexing and encapsulation equipment because Ethernet and STS48 use different physical and protocol layers.

Where is STS48 (signal) commonly used?

STS48 is used in telecommunications for high-capacity transport over optical fiber, including carrier long-haul, metro backbone, and data center interconnects.
