What does OC1 represent in optical networking?

OC1 is the basic optical transmission rate in SONET, operating at 51.84 megabits per second.

How is STS1 payload different from the OC1 line rate?

STS1 payload represents the user-data capacity inside the STS1 frame, which is slightly less than the OC1 line rate due to framing overhead.

Why is conversion from OC1 to STS1 payload important?

It helps network engineers understand the actual data throughput available for user traffic, aiding in bandwidth planning and provisioning.
