What is STS3c (payload) used for?

STS3c (payload) represents a SONET optical network payload channel that carries high-bandwidth client signals such as Ethernet or IP traffic across backbone links.

How does this tool convert STS3c (payload) to kilobytes per second?

It uses the fixed conversion rate where 1 STS3c (payload) equals 18351.5625 kilobytes per second following standard SONET payload specifications.

Why might the converted kilobyte/second value differ slightly from actual data rates?

Because the STS3c payload rate excludes SONET overhead and kilobytes here use decimal units, small differences can arise compared to real-world throughput.

What Is This Tool?

This converter transforms data transfer rates measured in STS3c (payload), a SONET signal unit used in optical networks, into kilobyte per second (kB/s), a common unit for expressing data throughput.

How to Use This Tool?

Enter the value in STS3c (payload) you want to convert
Select the unit STS3c (payload) as the input measurement
Choose kilobyte per second [kB/s] as the output unit
Click convert to see the equivalent data transfer rate in kB/s

Key Features

Converts STS3c (payload) units, representing optical network payload rates, into kilobyte/second values
Uses a precise conversion of 1 STS3c (payload) equaling 18351.5625 kB/s based on standard SONET payload rates
Supports understanding high-bandwidth circuit capacity in a unit friendly to IT and networking professionals

Examples

2 STS3c (payload) converts to 36703.125 kB/s
0.5 STS3c (payload) converts to 9175.78125 kB/s

Common Use Cases

Translating SONET optical network throughput into kilobytes per second for traffic monitoring
Reporting leased-line speeds in kilobytes per second for enterprise network management
Comparing optical backbone link capacities with typical data transfer units in IT environments

Tips & Best Practices

Remember that STS3c (payload) rates exclude SONET overhead, so actual usable throughput may be slightly less
Use the decimal SI definition of kilobyte (1 kB = 1,000 bytes) to align with this converter’s standard
Interpret results as approximate for steady data flows without considering additional network protocol overhead

Limitations

The nominal STS3c rate does not include SONET framing overhead bytes, so real payload throughput can be lower
Kilobyte/second here uses decimal SI units, which can differ from binary interpretations like kibibytes per second
Does not account for fluctuations from network conditions or overhead beyond SONET framing
