What does STM-4 (signal) represent?

STM-4 (signal) is a standardized optical transmission frame in the Synchronous Digital Hierarchy with a nominal rate of 622.08 Mbit/s, used in telecom networks for multiplexing digital traffic.

Why convert STM-4 (signal) to terabyte per second?

Converting STM-4 to terabyte per second helps express telecom optical rates in units common to high-performance computing and data center environments.

Does STM-4 rate represent pure data throughput?

No, STM-4 includes overhead bits for management and synchronization, so the payload data rate is slightly lower.
