What Is This Tool?
This converter allows you to translate data transfer speeds expressed in gigabyte per second (SI definition) into STM-4 (signal) units. Gigabyte per second uses decimal-based SI prefixes to quantify throughput, while STM-4 is a standardized optical transmission rate used in telecom networks. Converting between these units helps align device speeds with telecom infrastructure requirements.
How to Use This Tool?
-
Enter the value in gigabyte per second (SI definition) you want to convert.
-
Select the unit gigabyte/second (SI def.) as the source unit if needed.
-
Choose STM-4 (signal) as the target unit.
-
Click on convert to see the equivalent STM-4 (signal) value based on the fixed conversion rate.
Key Features
-
Converts gigabyte/second (SI def.) to STM-4 (signal) accurately based on standardized rates.
-
Browser-based and user-friendly interface for quick conversions.
-
Supports data transfer rate conversions relevant to telecommunications and data centers.
Examples
-
2 gigabyte/second (SI def.) equals 25.720164609 STM-4 (signal).
-
0.5 gigabyte/second (SI def.) equals 6.430041152 STM-4 (signal).
Common Use Cases
-
Determining backbone or aggregation link throughput in telecom networks.
-
Describing data center interconnect speeds using relevant network transport units.
-
Matching storage device or memory bandwidth rates to optical transport levels.
-
Configuring interconnections and multiplexing between SDH and Ethernet or ATM services.
Tips & Best Practices
-
Use this conversion to align generic data rates with SDH optical transmission standards.
-
Be aware that STM-4 provides a nominal line rate including overhead and synchronization.
-
Consider the difference between decimal-based SI units and binary-based data rates when comparing.
-
Verify network requirements to ensure correct unit usages for provisioning and aggregation.
Limitations
-
STM-4 line rate is fixed and does not reflect overhead beyond SDH framing details.
-
Gigabyte/second in SI terms may differ from binary data rate measurements.
-
Assumes ideal throughput without loss or encoding overhead outside the SDH protocol.
