Based on nominal data rates specified in telecom and networking standards.
Helps bridge understanding between SONET transport payloads and Ethernet LAN speeds.
Applicable for network planning, provisioning, and service billing contexts.
Simple, browser-based conversion with easy-to-understand results.

Examples

2 STS3 (payload) equals 3.00672 Ethernet (fast).
0.5 STS3 (payload) converts to 0.75168 Ethernet (fast).

Common Use Cases

Network engineers provisioning carrier backbone links with OC-3 circuits.
Integrating SONET transport capacity with Ethernet local area networks.
Measuring and billing leased-line services based on payload bandwidth allocation.
Planning network uplinks where legacy Fast Ethernet speeds are sufficient.
Supporting carriers and service providers managing mixed SONET and Ethernet networks.

Tips & Best Practices

Verify the units before converting to ensure accurate interpretation.
Keep in mind that this conversion uses nominal rates and does not include protocol overhead.
Use the tool to aid capacity planning rather than exact performance measurement.
Understand the context in which payload capacity relates to Ethernet speeds for network design.
Complement conversions with knowledge of actual frame encapsulation and network conditions.

Limitations

Nominal conversion rates do not include overhead, errors, or protocol framing specifics.
Differences between SONET payload framing and Ethernet frames affect real throughput.
Fast Ethernet caps at 100 Mbps, so conversions compare relative capacities rather than absolute equivalence.
