What does OC768 represent?

OC768 is an optical carrier rate in the SONET hierarchy with a line speed of approximately 39.8 Gbit/s, used for high-capacity fiber-optic backbone links.

What is STM-64 (signal)?

STM-64 is a signal in the Synchronous Digital Hierarchy with a line rate of roughly 10 Gbit/s, functionally equivalent to SONET OC-192/STS-192.

Why convert from OC768 to STM-64 (signal)?

Converting helps translate between SONET and SDH network layers for compatibility, capacity planning, and equipment interconnection.

Is the conversion exact for usable bandwidth?

No, the conversion reflects equivalence in line rate but actual usable bandwidth may be affected by overhead, framing, and multiplexing details.
