What does OC48 represent in data transfer terms?

OC48 is a SONET optical transmission rate of 2.48832 Gbit/s standardized for high-capacity synchronous optical networking.

What is the meaning of STS3 (payload)?

STS3 (payload) denotes the user-data portion of an STS-3 frame, representing the capacity available for carrying client traffic after subtracting SONET framing and overhead.

Why convert OC48 to STS3 (payload)?

Converting OC48 to STS3 (payload) helps in translating high-level transmission rates into usable payload channels for capacity planning, provisioning, and billing.
