What Is This Tool?
This converter enables you to translate data transfer rates from Ethernet (fast), a standard for 100 Mbit/s local-area networking, into STS1 (signal), the fundamental SONET transport unit at 51.84 Mbit/s. It helps bridge Ethernet technologies with synchronous optical networking.

Integrating enterprise legacy Ethernet with synchronous optical networks
Tips & Best Practices
-
Use the tool for planning and theoretical rate conversions
-
Consider differences in framing and encoding between Ethernet and SONET
-
Verify actual throughput separately since protocol overheads can vary
-
Apply conversion mainly for interoperability and infrastructure design
Limitations
-
Conversion reflects nominal data rates, not actual throughput
-
Framing and encoding differences affect bandwidth utilization accuracy
-
Primarily theoretical; real-world applications require protocol-specific adjustments
Frequently Asked Questions
-
What is the nominal data rate of Fast Ethernet?
-
Fast Ethernet provides a nominal data rate of 100 megabits per second.
-
What does STS1 (signal) represent in networking?
-
STS1 is the basic SONET electrical/frame unit carrying a line rate of 51.84 megabits per second and is fundamental for synchronous optical networking.
-
Can this conversion be used for actual network throughput measurements?
-
No, the conversion is theoretical and based on nominal rates; actual throughput depends on protocol overhead and framing.
Key Terminology
-
Ethernet (fast)
-
