What does 1 STS3 (signal) equal in Ethernet (fast)?

1 STS3 (signal) equals 1.5552 Ethernet (fast), indicating the data rate equivalence between these two standards.

Can I directly replace a STS3 line with a Fast Ethernet link?

No, because STS3 and Fast Ethernet operate at different speeds and protocols; conversion requires equipment that manages protocol differences and bandwidth.

Tips & Best Practices

Always verify network equipment compatibility when bridging SONET with Ethernet standards.
Use this conversion for capacity planning rather than direct hardware interoperability assumptions.
Consider physical media and protocol differences when designing network interfaces.
Account for protocol adaptation needed to handle data rate integration.

Limitations

STS3 runs at a fixed 155.52 Mbps while Fast Ethernet is nominally 100 Mbps, requiring bandwidth management.
Conversion reflects conceptual equivalence and not direct physical interoperability.
Physical media and protocol differences mean actual integration needs supporting network equipment.
Fast Ethernet links do not natively support SONET framing, so extra protocol adaptation is necessary.
