What is STM-4 (signal) used for?

STM-4 (signal) is an optical transmission standard used in telecom for multiplexing and transporting digital data at a nominal line rate of 622.08 Mbit/s.

How is a kilobyte per second (SI definition) different from a kibibyte per second?

A kilobyte per second (SI) equals 1000 bytes per second, whereas a kibibyte per second equals 1024 bytes per second, reflecting different prefix standards.

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

Converting helps represent high-speed optical data in byte-based units commonly used in application reporting and hardware specifications.

Key Features

Converts high-speed optical data rates from STM-4 (signal) to kilobyte/second (SI).
Uses standardized SI prefixes for byte-based data transfer rate representation.
Supports easy interpretation of telecom SDH optical transmission in application-level units.

Examples

2 STM-4 (signal) equals 155520 kilobyte/second (SI def.).
0.5 STM-4 (signal) converts to 38880 kilobyte/second (SI def.).

Common Use Cases

Calculating high-speed optical network transfer rates in byte-based units for monitoring and planning.
Converting STM-4 rates to kilobyte/second for application-level data throughput reporting.
Interpreting telecom SDH optical backbone speeds in terms suitable for hardware specifications.

Tips & Best Practices

Remember that kilobyte/second uses SI decimal prefixes (1000 bytes) different from binary prefixes.
Use the conversion mainly for representing throughput where byte-level reporting is more applicable than bit-level.
Keep in mind STM-4 rates include overhead bits, so exact payload rates may vary.

Limitations

Conversion is based on SI kilobyte definitions, not binary kibibytes.
STM-4 data rates include overhead, so actual user payload throughput might differ slightly.
Does not provide conversions for units outside STM-4 and kilobyte/second as defined.
