What Is This Tool?
This tool allows you to convert data transfer rates from a modem operating at 28.8 kilobits per second to an STM-64 (signal) rate, used in high-capacity fiber optic networks. It helps illustrate the differences between legacy dial-up speeds and current optical communication rates.
How to Use This Tool?
-
Enter the value in modem (28.8k) units you want to convert
-
Select STM-64 (signal) as the output unit

Examples
-
10 modem (28.8k) converts to approximately 0.000028935185185185 STM-64 (signal)
-
1000 modem (28.8k) converts to about 0.0028935185185185 STM-64 (signal)
Common Use Cases
-
Estimating and comparing download times on older dial-up connections
-
Aggregating and understanding data rates from legacy modems in relation to modern high-speed fiber channels
-
Planning and upgrading network infrastructures bridging analog and digital networks
-
Educational and research purposes to study transitions in telecommunications
Tips & Best Practices
-
Remember that this conversion is theoretical due to vastly different scales
-
Consider protocol overhead and equipment differences when interpreting results
-
Use this tool to gain perspective on the evolution of data transfer technologies
-
Apply conversions carefully in network planning with supplementary technical assessments
Limitations
-
Conversions span vastly different data rates, making them mostly illustrative
-
Does not account for real-world transmission inefficiencies or overhead
-
Direct usage of modem signals over STM-64 lines requires additional adaptation or multiplexing
Frequently Asked Questions
-
What does modem (28.8k) represent?
-
It is an informal term for a data transfer rate of approximately 28.8 kilobits per second, typical of a 28.8k dial-up modem over analog telephone lines.
-
What is STM-64 (signal)?
-
STM-64 is a Synchronous Transport Module level-64 signal used in high-capacity fiber-optic networks, with a line rate near 10 Gbit/s.
-
Why convert between modem (28.8k) and STM-64 (signal)?
-
Converting helps compare old dial-up speeds with modern optical network rates to understand scale differences and assist in network planning or educational contexts.
