What does converting from OC3 to STM-16 (signal) mean?

It means translating data rates between SONET OC3 (155.52 Mbps) and SDH STM-16 (2.48832 Gbit/s) standards used in telecom networks.

Why is this conversion useful in telecom?

It helps integrate different transmission standards, enabling interoperability in backbone and long-haul fiber optic networks.

Are these units interchangeable without additional equipment?

No, devices must support respective SONET or SDH protocols and may require adaptation for framing differences.
