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

It is a data transfer rate equaling 10^12 bits transmitted every second using decimal prefixes.

What is the capacity of an STS1 (payload) unit?

STS1 payload carries a usable synchronous payload envelope of about 50.112 Mbps.

Why convert terabit/second to STS1 (payload)?

To translate high-level data rates into SONET payload units for provisioning and capacity planning in optical networks.

How to Convert from Terabit/second (SI def.) to STS1 (payload)?

What Is This Tool?

This converter translates data transfer speeds measured in terabit per second (SI definition) into STS1 (payload) units, facilitating the management and planning of optical transport networks.

How to Use This Tool?

Enter the data transfer rate value in terabit/second (SI def.)
Select the original unit as terabit/second (SI def.)
Choose the target unit as STS1 (payload)
Click ‘Convert’ to see the equivalent value in STS1 (payload)

Key Features

Converts high-speed data rates from terabit/second (SI def.) to STS1 (payload)
Helps interpret data transfer metrics in standardized SONET payload units
Supports use cases including carrier backbone provisioning and data center interconnects
Simple and browser-based user interface for quick conversions

Examples

0.5 Terabit/second converts to approximately 10101.01 STS1 (payload)
2 Terabit/second converts to approximately 40404.04 STS1 (payload)

Common Use Cases

Translating terabit-level data rates into SONET STS1 payload units for carrier backbone provisioning
Capacity planning and throughput analysis for SONET ring networks
Mapping tributary signals such as ATM cells or Ethernet frames into STS1 synchronous payload envelopes
High-capacity data center interconnect management for cloud providers and scientific data transfers

Tips & Best Practices

Ensure units are correctly selected before conversion to avoid confusion
Use this tool to assist in optical transport network capacity planning and provisioning
Be mindful that STS1 (payload) has fixed capacity limits requiring aggregation for large terabit rates
Remember the SI terabit uses decimal prefixes which differ from binary-based units

Limitations

STS1 payload capacity is fixed near 50.112 Mbps, requiring many STS1 channels to represent large terabit rates
The decimal-based SI terabit differs from binary units like tebibit, which can cause confusion
This tool does not apply to non-standard or binary-based data transfer units

20202.02020202 STS1 (payload)

1000 STS1 (payload)

Which unit has a fixed capacity of approximately 50.112 Mbps?

Terabit/second (SI def.)

STS1 (payload)

Tebibit

Why must many STS1 channels be aggregated to represent terabit rates?

Because STS1 channels are limited to about 50 Mbps each

Because terabit is a binary unit

Because STS1 is a newer technology
