What Is This Tool?
This online converter helps you translate data transfer rates from OC1, a base level SONET optical transmission standard, to IDE (PIO mode 3), an older programmed I/O mode for Parallel ATA storage devices. It is useful for comparing high-speed optical network rates to legacy IDE device throughput.
How to Use This Tool?
-
Enter the value in OC1 units that you want to convert.
-
Select IDE (PIO mode 3) as the target unit for conversion.
-
Click the convert button to see the equivalent transfer rate.
-
Review the output, which reflects the theoretical maximum throughput.
-
Use the results to understand and compare different data transfer technologies.

-
Browser-based tool requiring no installation.
Examples
-
Convert 2 OC1 units: 2 OC1 = 1.1675675676 IDE (PIO mode 3).
-
Convert 5 OC1 units: 5 OC1 = 2.918918919 IDE (PIO mode 3).
Common Use Cases
-
Provisioning carrier-grade leased fiber circuits using OC1 rates.
-
Multiplexing multiple OC1 signals to form higher-rate SONET trunks.
-
Aggregating low-speed channels onto an optical backbone.
-
Interfacing with legacy IDE storage devices in embedded or industrial systems.
-
Conducting performance comparisons or retrocomputing tests of storage modes.
Tips & Best Practices
-
Understand that OC1 reflects optical line transmission rates while IDE rates are device-level throughputs.
-
Use conversion results as theoretical references, not exact real-world performance figures.
-
Consider protocol overhead and hardware limitations when interpreting results.
-
Use this tool to bridge understanding between modern networking and legacy storage technologies.
-
Apply conversions carefully in testing or benchmarking scenarios involving old and new systems.
Limitations
-
Conversion is based on theoretical maximum rates and may not reflect actual throughput.
-
IDE (PIO mode 3) limitations include CPU-driven operation and older technology constraints.
-
OC1 values represent optical line rates, which differ in nature from device-level IDE throughputs.
-
Real performance can be affected by protocol overhead, hardware, and environmental conditions.
Frequently Asked Questions
-
What does OC1 represent in data transfer?
-
OC1 is the base SONET optical transmission rate of 51.84 megabits per second, corresponding to an STS-1 electrical signal used in synchronous optical networking.
-
What is IDE (PIO mode 3)?
-
IDE (PIO mode 3) is a CPU-driven programmed I/O transfer mode for Parallel ATA storage devices with a theoretical maximum throughput of about 11.1 megabytes per second.
-
Why convert from OC1 to IDE (PIO mode 3)?
-
Converting helps compare high-capacity optical network rates with legacy IDE device transfer speeds, useful in retrocomputing and performance benchmarking.
