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

It is a unit of data transfer rate equal to 10^12 bits transmitted each second, indicating how fast digital data is moved based on SI decimal prefixes.

Why is STS3c (payload) used as a conversion target?

STS3c (payload) represents SONET transport channels used in optical networks for carrying high-bandwidth client signals, making it useful for network planning.

Are the conversions exact usable data rates?

No, the actual usable payload is slightly lower than the gross STS3c rate due to SONET framing and overhead bytes, so conversions are approximate.

What Is This Tool?

This unit converter translates data transfer rates measured in terabits per second (SI definition) into STS3c (payload) units, which represent contiguous SONET transport channels for high-bandwidth network signals.

How to Use This Tool?

Enter the data rate value in terabit per second (SI definition).
Select STS3c (payload) as the output unit.
Initiate the conversion to view the equivalent number of STS3c payload containers.

Key Features

Converts terabit/second (SI def.) to STS3c (payload) for telecommunications and networking use.
Supports high-capacity data transfer rate measurements relevant to optical transport and backbone links.
Provides practical conversions to SONET payload containers for network capacity planning.

Examples

2 terabits/second equals approximately 13303.53 STS3c (payload).
0.5 terabit/second converts to about 3325.88 STS3c (payload).

Common Use Cases

Evaluating capacity for backbone optical-fiber and wavelength-division multiplexing (WDM) links.
Planning high-speed data center interconnects for hyperscale cloud providers.
Managing transported client signals such as Ethernet, IP, ATM, or frame relay over optical networks.
Providing leased-line service for enterprises requiring roughly 155 Mbps circuits.

Tips & Best Practices

Verify that the input data rate follows the SI decimal standard, not binary prefix units.
Consider SONET framing overhead which slightly reduces usable payload capacity.
Use this conversion to assist with network resource allocation and infrastructure planning.

Limitations

STS3c payload's usable bandwidth is somewhat less than its gross rate due to SONET framing overhead.
Terabit per second values follow SI definitions and should not be confused with binary prefix units like tebibit.
The conversion reflects continuous data throughput and may not account for transient network variances or additional protocol overhead beyond SONET framing.
