What does 1 STM-64 (signal) equal in OC768?

1 STM-64 (signal) is equivalent to 0.25 OC768.

Why convert between STM-64 and OC768 units?

Conversions help compare and aggregate data rates across SDH and SONET standards and assist in capacity planning for fiber optic networks.

Are STM-64 and OC768 interchangeable?

They represent different network hierarchies (SDH and SONET) and have slight implementation differences, so they are not directly interchangeable but can be converted for planning purposes.
