What does gigabit per second (Gb/s) measure?

Gigabit per second (Gb/s) measures the speed of data transfer, indicating how many billion bits are transmitted each second.

What is STS1 (payload) in SONET?

STS1 (payload) in SONET is the user-data capacity within an STS1 frame, with a line rate of 51.84 Mbps and usable payload around 50.112 Mbps.

Why convert Gb/s to STS1 (payload)?

Converting Gb/s to STS1 (payload) helps telecom professionals plan and provision optical networks by translating general bandwidth into SONET-specific payload units.

What Is This Tool?

This converter transforms data transfer speeds measured in gigabits per second (Gb/s) into STS1 (payload) units used in SONET networks. It helps interpret general bandwidth specifications into SONET payload capacities for network provisioning and planning.

How to Use This Tool?

Enter a data transfer speed value in gigabit/second (Gb/s)
Select the source unit as gigabit/second [Gb/s]
Choose the target unit STS1 (payload)
Click convert to view the equivalent STS1 payload capacity

Key Features

Converts gigabit/second (Gb/s) values to STS1 (payload) units
Applies the specific conversion rate based on SONET payload standards
Supports planning and provisioning in optical fiber and carrier networks
User-friendly interface suitable for network engineers and data center professionals

Examples

1 Gb/s equals approximately 21.69 STS1 (payload)
5 Gb/s converts to about 108.46 STS1 (payload)

Common Use Cases

Translating high-speed network bandwidth into SONET-specific payload units
Provisioning OC‑1/STS‑1 circuits for carrier backbone networks
Planning capacity for SONET rings and service-level throughput
Mapping tributary signals into STS‑1 payloads for optical transport

Tips & Best Practices

Verify the type of network to ensure SONET applicability
