What does STM-4 (signal) represent?

STM-4 (signal) is a standard optical transmission frame in the Synchronous Digital Hierarchy with a nominal line rate of 622.08 Mbit/s used for carrying payload and overhead.

Why convert STM-4 (signal) to kilobit/second?

Converting to kilobit/second allows expressing optical data rates in a widely recognized unit, facilitating performance comparison and interoperability with other network equipment.

Can this conversion be used for low bandwidth links?

High data rates like STM-4 are less meaningful in low bandwidth contexts where kilobit/second is typically applied, so this conversion is mainly useful in telecom backbone networks.

Tips & Best Practices

Consider that STM-4 rates include overhead, so actual payload throughput may be lower
Use kilobit/second (SI) units to compare with other network technologies reporting speeds in decimal multiples
Apply this conversion mainly in telecommunications and backbone network planning contexts
Avoid using high-rate STM-4 conversions for low bandwidth or narrowband telemetry links

Limitations

STM-4 data rates incorporate overhead, impacting exact payload measurements
Kilobit/second (SI) units use decimal multiples, different from some binary-based computing units
High data rate concepts like STM-4 are less suitable for scenarios focused on very low bandwidth
