Tips & Best Practices

Ensure physical interface compatibility when integrating systems using these conversions.
Consider the signaling method differences (parallel vs. optical synchronous) in deployment.
Use the conversion rate for rate translation, but account for protocol overhead separately.
Validate that the converted values fit the requirements of the target network or device standards.

Limitations

Differences in signaling methods may affect interoperability beyond raw data rates.
Conversion focuses on rate values and does not cover protocol overhead or framing.
Physical interface and signal format compatibility must be evaluated separately.
