-
Easy to use web-based interface requiring no installation.
-
Provides clear examples of STM-1 to Ethernet conversions.
Examples
-
1 STM-1 (signal) equals 15.552 Ethernet.
-
2 STM-1 (signal) equals 31.104 Ethernet.
Common Use Cases
-
Provisioning 155.52 Mbps backbone fiber links in telecommunications.
-
Aggregating lower-rate tributary circuits over SDH networks.
-
Integrating legacy SDH transport equipment with Ethernet LAN or metro networks.
-
Planning network capacity by comparing SDH and Ethernet data rates.
Tips & Best Practices
-
Understand that Ethernet defines various link speeds, so conversion is approximate.
-
Use this tool to assist in network design and equipment interoperability.
-
Verify conversions with actual network configurations due to overhead differences.
-
Consider Ethernet variations when comparing with STM-1 (signal) rates.
Limitations
-
Ethernet includes multiple protocols with different link speeds, affecting direct equivalence.
-
STM-1 is a specific synchronous transport rate, while Ethernet framing and speeds vary.
-
Overhead and framing differences mean throughput may not exactly match between the two.
-
This tool offers approximate conversions useful mainly for planning and comparison.
Frequently Asked Questions
-
What is STM-1 (signal)?
-
STM-1 (signal) is the basic transmission unit in the Synchronous Digital Hierarchy (SDH), carrying a synchronous framed signal at 155.52 Mbit/s, used mainly in telecom backbone networks.
-
How does Ethernet relate to STM-1?
-
Ethernet is a family of networking protocols for LANs with various data rates, while STM-1 is a fixed SDH transport rate. This converter relates their data transfer rates for compatibility and planning.
-
Can I use this tool for exact network configuration?
-
No, because of differences in framing and overhead, conversions are approximate and intended for planning and capacity comparison rather than precise configuration.
