What does STS12 (signal) represent?

STS12 (signal) is a synchronous transport signal level used in SONET networks, with a line rate of 622.08 Mbit/s that includes overhead for framing and management.

Why is gigabyte per second (SI def.) used for conversion?

Gigabyte per second (SI def.) provides a decimal-based standardized unit for measuring data throughput, facilitating comparison with other network and storage speeds.

Does the conversion reflect actual data payload transfer?

No, the conversion uses the nominal line rate including SONET overhead; actual payload throughput may be lower.

Tips & Best Practices

Remember that STS12 data rates include SONET protocol overhead, so payload may be lower
Use gigabyte per second (SI) for comparisons requiring decimal-based units
Be aware that binary gigabyte definitions differ from SI-based throughput units
Apply conversions when evaluating telecom backbone performance or data center networking
Consider steady-state rates as the conversion does not account for protocol or congestion variability

Limitations

STS12 unit reflects line rate including SONET overhead, not pure payload throughput
Gigabyte per second (SI) uses decimal prefixes differing from binary-based gigabyte units found in some systems
Conversion assumes stable line conditions, ignoring possible protocol overhead or network congestion impacts
