What is Ethernet (fast)?

Ethernet (fast) refers to IEEE 802.3 standards providing a nominal data rate of 100 megabits per second, typically used in local-area networking.

What does STS1 (payload) represent?

STS1 (payload) is the user-data capacity inside an STS-1 SONET frame with a usable throughput of about 50.112 Mbps.

Why convert Ethernet (fast) to STS1 (payload)?

Users convert these units to plan and provision telecommunications circuits, ensuring alignment between Ethernet LAN speeds and SONET optical transport capacities.

Enter the value in Ethernet (fast) units that you want to convert.
Select Ethernet (fast) as the source unit and STS1 (payload) as the target unit.
Click convert to obtain the equivalent STS1 (payload) value.

Key Features

Accurate conversion from Ethernet (fast) to STS1 (payload) using established conversion rates.
Simple interface suitable for network engineers and telecom professionals.
Supports calculations relevant to provisioning and capacity planning.

Examples

1 Ethernet (fast) equals approximately 2.02 STS1 (payload).
5 Ethernet (fast) equals roughly 10.10 STS1 (payload).

Common Use Cases

Telecommunication carriers provisioning SONET/SDH backbone networks.
Network engineers performing capacity planning for optical transport systems.
Internet service providers mapping Ethernet-based traffic into SONET payload envelopes.

Tips & Best Practices

Use this tool primarily for planning and provisioning where nominal data rates apply.
Consider the fixed payload rate of STS1 when analyzing throughput capacity.
Be aware that real-world overhead may affect actual data transmission speeds.

Limitations

Ethernet (fast) is nominally 100 Mbps, while STS1 payload is capped at 50.112 Mbps, reflecting protocol and framing overhead.
Conversion assumes continuous data flow and does not account for network inefficiencies.
STS1 payload rates are fixed by SONET standards and may limit actual throughput depending on network setups.
