Why convert between STS3 (signal) and OC3?

Converting helps network engineers design and manage equivalent capacities across both electrical and optical SONET infrastructure for telecom and ISP networks.

Does the conversion account for physical differences in transmission?

No. While data rates are equivalent, the conversion does not consider physical medium variations, latency, or signal overhead.

How to Convert from STS3 (signal) to OC3?
