What does Ethernet (fast) refer to in this conversion?

Ethernet (fast) refers to the IEEE 802.3 standards family providing 100 megabits per second data rate, commonly used in small office or home LANs.

What is STS3c (signal) used for?

STS3c (signal) is a SONET electrical transport signal with a 155.52 Mbps rate, used in telecom networks for provisioning backbone or leased-line circuits.

Why is the conversion factor less than one?

Because Ethernet (fast) offers 100 Mbps while STS3c provides 155.52 Mbps, the conversion factor reflects the ratio of these rates, resulting in a value less than one.

Can this converter be used for all SONET equipment?

No, some SONET equipment may not support concatenation or Ethernet encapsulation needed for this conversion to be practical.

Common Use Cases

Bridging 100 Mbps Ethernet LAN connections to SONET backbones operating at 155.52 Mbps
Encapsulating Ethernet traffic into telecom-grade SONET equipment for backbone or leased lines
Provisioning metro or backbone SONET circuits using OC-3c/STS-3c signals
Interconnecting SONET devices to carry aggregated network traffic efficiently

Tips & Best Practices

Ensure the conversion is used for ideal scenarios without overhead or framing considerations
Verify compatibility of SONET hardware with concatenated payloads and Ethernet encapsulation
Use the tool to estimate bridging capacities between Ethernet and SONET layers
Consider practical network conditions for throughput when applying conversion results

Limitations

The 100 Mbps Ethernet rate is lower than the 155.52 Mbps STS3c signal, so the conversion value is less than one
Conversion does not account for protocol overhead, framing, or encapsulation inefficiencies
Not all SONET equipment supports seamless concatenation or Ethernet encapsulation, restricting usage
Results assume ideal conditions and may not reflect actual throughput in deployed networks
