What does 1 terabit per second represent?

It represents a data transfer rate of one trillion bits per second, quantifying digital information throughput in networks.

What is STM-4 (signal) used for?

STM-4 is a standardized optical transmission frame used for multiplexing and carrying digital traffic in telecom networks, with a nominal line rate of 622.08 Mbit/s.

Can I directly compare terabit/second rates and STM-4 signals?

You can convert between these units to understand scale, but STM-4 signal rates include overhead and are physical transmission units, unlike pure data throughput in terabit/second.

Uses a precise, fixed conversion rate based on standardized telecom framing
Supports understanding of high-capacity optical transport and carrier networks
Provides examples for quick reference and practical application
Browser-based and easy to use for network engineers and planners

Examples

Converting 1 Tb/s results in approximately 1767.476 STM-4 (signal)
Converting 2 Tb/s results in approximately 3534.952 STM-4 (signal)

Common Use Cases

Mapping ultra-high data throughput onto standardized SDH optical transmission rates
Planning and testing carrier-grade backbone network capacities
Aggregating multiple lower-rate telecom circuits into higher-level signals
Designing telecom infrastructure for long-haul and regional optical links

Tips & Best Practices

Remember STM-4 reflects nominal physical line rate including overhead, not pure payload throughput
Use this conversion as a guideline for capacity planning rather than final network performance metrics
Double-check unit selections to ensure accurate rate conversions
Consider protocol and encoding factors separately when analyzing real-world throughput

Limitations

STM-4 (signal) includes both data payload and overhead, so it does not represent only usable data rate
Conversion is idealized and does not account for line impairments or encoding inefficiencies
Actual throughput may vary due to physical network conditions and protocol overhead
