What does 1 Gb/s represent?

One gigabit per second represents the rate of data transfer equal to one billion bits transmitted each second, commonly used to specify bandwidth of network links.

What is STM-4 (signal) used for?

STM-4 (signal) is a standardized optical transmission module in the Synchronous Digital Hierarchy used for multiplexing digital traffic across telecom networks.

Why convert Gb/s to STM-4 (signal)?

Converting helps understand and plan for actual multiplexed optical transport capacities that include both payload and overhead management data.

Supports data transfer measurements relevant to telecommunications and networking
Browser-based and easy-to-use interface
Provides clear examples for practical conversions
Useful for network planning and capacity assessment in optical transport systems

Examples

1 Gb/s is converted to approximately 1.726 STM-4 (signal)
10 Gb/s equals roughly 17.2605 STM-4 (signal)

Common Use Cases

Specifying network interface and fiber-optic link speeds
Planning ISP broadband and home router throughput capacities
Analyzing data center interconnect and storage network performance
Designing regional or inter-city optical backbone links
Aggregating multiple STM-1 signals in carrier networks
Transporting wholesale Ethernet, ATM, or other telecom services over SDH infrastructure

Tips & Best Practices

Ensure correct input of gigabit per second values to avoid errors
Understand that STM-4 units include overhead for management and synchronization
Use conversion results to plan network capacity rather than exact payload rates
Consider the impact of protocol and network variations when applying conversions

Limitations

STM-4 includes overhead bits, so payload rates differ from raw Gb/s values
Conversion assumes nominal SDH line rates without network condition variations
Does not reflect specific protocol or implementation differences in transport
