What does megabyte per second (SI def.) represent?

It represents a data transfer rate equal to 1,000,000 bytes transferred every second using decimal SI units, distinct from binary-based measurements.

What is STM-4 (signal) used for?

STM-4 is a standardized optical transmission frame in the SDH hierarchy used to carry digital traffic including payload and management overhead over telecom networks.

Can this conversion account for actual network performance?

No, the conversion is based on nominal line rates and does not include protocol overhead or real-world line impairments affecting throughput.

Common Use Cases

Reporting sequential read and write speeds of storage devices in MB/s
Specifying file transfer speeds over interfaces like USB or Ethernet using SI units
Aggregating voice, data, and leased circuits over regional optical backbone links
Interconnecting multiple lower-rate PDH/SDH circuits within carrier networks
Transporting wholesale Ethernet, ATM, or other services through SDH infrastructure

Tips & Best Practices

Confirm that megabyte/second values are using the SI decimal definition for accuracy
Understand that STM-4 conversions rely on nominal line rates, not actual throughput
Use this conversion for planning optical network capacities rather than real-time performance
Be aware of differences between decimal-based and binary-based data transfer units
Employ the tool to facilitate communication between data storage and telecom network teams

Limitations

Conversion is based on nominal line rates and excludes protocol overhead or line impairments
Megabyte/second uses decimal SI units, which differ from binary-based units and can cause confusion
STM-4 represents a fixed optical transmission rate and actual throughput can vary with network conditions and multiplexing efficiency
