What does terabyte per second (TB/s) measure?

Terabyte per second (TB/s) represents the amount of data transferred every second, equaling one trillion bytes per second according to SI units.

What is STM-4 (signal) used for?

STM-4 (signal) is an optical transmission module in the Synchronous Digital Hierarchy system used to transport and multiplex digital traffic in telecommunication networks.

Why is the conversion from TB/s to STM-4 approximate?

The conversion is approximate because TB/s measures raw data rates, whereas STM-4 includes overhead for management and synchronization within a fixed optical transport frame.

What Is This Tool?

This unit converter translates data transfer rates from terabyte per second (TB/s), a high-bandwidth measurement, into STM-4 (signal) units, standardized optical transport modules used in synchronous digital hierarchy systems. It aids in bridging modern storage and computing speeds with telecom infrastructure specifications.

How to Use This Tool?

Enter the data transfer rate value in terabytes per second (TB/s) into the input field
Select 'terabyte/second [TB/s]' as the source unit
Choose 'STM-4 (signal)' as the target unit for conversion
Click the convert button to obtain the equivalent value in STM-4 units
Use the result to assist in network planning or capacity management tasks

Key Features

Supports high-level bandwidth measurements relevant to data centers, supercomputers, and telecom networks
Provides clear conversion examples for quick reference
Browser-based and easy-to-use interface for fast calculations
Helps network professionals align storage and compute throughput with SDH telecom standards

Examples

1 TB/s equals approximately 14,139.81 STM-4 (signal)
0.5 TB/s converts to about 7,069.90 STM-4 (signal)

Common Use Cases

Converting aggregate throughput of high-performance NVMe SSD arrays to telecom-compatible units
Planning data-center backbone links with high bandwidth requirements
Managing interconnections in supercomputing accelerator-to-memory links
Translating high data rates for integration with standard SDH optical transport networks
Sizing regional or inter-city optical backbone links in carrier networks

Tips & Best Practices

Double-check the data units to ensure correct input as TB/s for accurate conversion
Use this tool for capacity planning rather than exact payload calculations due to overhead in STM-4 signals
Consider the difference between raw data rates and framed transport capacities when interpreting results
Apply conversion results to assist with telecom network design and upgrade decisions
Consult network documentation to understand how STM-4 overhead impacts actual throughput

Limitations

STM-4 rates are nominal and include overhead, so the actual payload is lower than the converted value
Terabyte/second measures raw transfer speeds whereas STM-4 reflects SDH framing, causing approximate conversion results
This converter is best suited for planning purposes, not for exact bit-for-bit data comparisons
Does not account for variations in binary versus decimal bytes despite the terabyte definition
Conversion does not substitute for detailed protocol-specific analysis or real-world network performance
