What does gigabyte/second (SI def.) measure?

It measures data transfer rate using the decimal definition where 1 gigabyte equals 10^9 bytes transferred each second.

What is STS3c (payload)?

STS3c (payload) is a SONET transport signal providing a single contiguous channel with a nominal line rate of 155.52 Mbps for carrying high-bandwidth client signals.

Why can't partial STS3c channels be used?

In practice, STS3c channels are allocated as whole units due to SONET framing and structural constraints in optical networks.

What Is This Tool?

This converter transforms data transfer rates measured in gigabyte per second (using the SI decimal definition) into STS3c (payload) units within the SONET framework. It helps quantify and plan network throughput in optical transport systems.

How to Use This Tool?

Enter the data transfer rate in gigabyte/second (SI definition).
Select STS3c (payload) as the target unit for conversion.
Click convert to obtain the equivalent STS3c payload channels.
Use the results to estimate the required number of SONET channels.

Key Features

Transforms gigabyte/second (SI def.) to STS3c (payload) data rates accurately.
Supports data transfer measurement specific to optical transport and telecommunications.
Facilitates network planning for backbone optical links and leased-line services.
Browser-based, easy to use without software installation.

Examples

1 GB/s equals approximately 53.214 STS3c (payload) channels.
0.5 GB/s converts to about 26.607 STS3c (payload) channels.

Common Use Cases

Translating data throughput rates from decimal gigabytes per second to SONET payload units for optical network capacity planning.
Planning backbone optical links carrying Ethernet or IP circuits over OC-3 connections.
Determining leased-line bandwidth requirements in enterprise networks using STS-3c circuits.

Tips & Best Practices

Round conversion results to whole STS3c channels since partial channels are not usable.
Consider overhead and framing when interpreting STS3c payload results, as usable payload is slightly less than nominal rates.
Use this conversion for decimal-based data rates in telecommunications and data center network planning.

Limitations

STS3c (payload) nominal rates include overhead and framing, which reduce actual usable payload slightly.
Gigabyte/second (SI def.) values are decimal and do not reflect binary prefixes used in some storage contexts.
Partial STS3c channels cannot be allocated, so conversion outputs need adjustment for practical deployment.
