Tips & Best Practices
-
Consider that STM-4's line rate includes management overhead which affects actual payload
-
Account for Ethernet overhead when analyzing effective throughput
-
Use the converter for raw data rate comparison only, not for protocol or framing compatibility
-
Verify network hardware compatibility when planning integrations
Limitations
-
STM-4 includes synchronization and management overhead bits affecting actual throughput
-
Fast Ethernet speeds are nominal and can vary due to network overhead and protocols
-
Conversion focuses on raw data transfer rates, excluding network layer differences
