What does 1 Mb/s represent in data transfer?

1 Mb/s stands for one million bits transferred per second, commonly used to measure network bandwidth.

What is STM-4 (signal) used for?

STM-4 is a standardized optical transmission level in SDH, used for multiplexing and carrying digital traffic over telecom networks.

Why might actual throughput be less than the nominal STM-4 rate?

Because STM-4 carries overhead and framing data required for management and synchronization, reducing usable payload capacity.

Key Features

Converts megabit/second (Mb/s) to STM-4 (signal) reflecting SDH standards
Provides a simple, browser-based interface for quick calculations
Useful for telecommunications and network infrastructure planning
Shows examples of typical conversions for clarity

Examples

100 Mb/s converts to approximately 0.16856 STM-4 (signal)
622.08 Mb/s equals about 1 STM-4 (signal), matching the nominal rate

Common Use Cases

Planning bandwidth for telecom optical backbone links
Aligning consumer or enterprise rates with SDH optical standards
Aggregating lower-rate circuits into higher-level STM-4 signals
Managing inter-city or regional network transport capacity

Tips & Best Practices

Use this converter to relate common Mbps rates to carrier optics
Consider overhead and framing data affecting actual throughput
Use nominal rates as guidelines rather than exact measures
Apply conversions in SDH-based network design and provisioning

Limitations

STM-4 includes overhead so actual throughput may be less than nominal
Real-world performance can vary with network conditions and protocols
STM-4 is specific to SDH networks, not directly used in pure Ethernet/IP setups
