What does STM-1 (signal) represent?

STM-1 (Synchronous Transport Module level-1) is the basic transmission unit in the Synchronous Digital Hierarchy standard, carrying a gross bit rate of 155.52 Mbit/s.

How is a megabyte per second (SI def.) defined?

It is a data transfer rate of one million (1,000,000) bytes per second, following the decimal SI system.

Why convert STM-1 to megabyte per second (SI def.)?

Converting allows telecom-grade transmission speeds to be expressed in common digital throughput units used in computing and storage systems.

Check converted output against your system's performance measurements
Apply the tool in engineering specs for video streaming and backup data rate planning

Limitations

STM-1 rate represents a fixed standard and may not reflect actual user data throughput
Megabyte per second (SI def.) uses decimal bytes differing from binary-based units, which can cause misunderstandings
Conversion assumes theoretical maximum speed; real-world rates may vary due to protocol or network overhead
