What is STS3 (signal)?

STS3 (signal) is a SONET digital transmission signal with a line rate of 155.52 megabits per second, commonly used in telecom networks to carry multiple lower-rate circuits.

What does terabyte/second (SI def.) mean?

Terabyte/second (SI def.) is a data transfer rate unit representing one trillion bytes moved each second, often used in high-performance computing and data center bandwidth measurements.

Why convert STS3 (signal) to terabyte/second (SI def.)?

Converting STS3 to terabyte/second helps compare legacy telecom data rates with modern standardized throughput units used in HPC and data centers.

Common Use Cases

Backbone telecom link bandwidth planning between central offices.
Measuring and comparing data center backbone link speeds.
Translating telecom data rates for integration with HPC cluster interconnects.
Specifying throughput for storage arrays and high-performance networks.
Converting legacy SONET signal rates into modern standard units.

Tips & Best Practices

Be aware that STS3 represents a fixed rate of 155.52 Mbps, which results in very small terabyte/second values.
Use this conversion to align telecom data rates with SI throughput metrics accurately.
Distinguish between SI terabytes and binary terabytes when working with storage versus transfer rates.
Verify the context of data rates — whether for networking or storage performance — before interpreting results.

Limitations

STS3's 155.52 Mbps speed is significantly lower than terabyte-per-second scales, causing conversions to be very small decimals.
Conversion applies only to data transfer rate units, not to storage capacity measurements.
Care is needed to interpret SI terabyte units correctly versus other terabyte definitions.
