What does OC48 stand for in data transfer?

OC48 is an Optical Carrier 48 standard representing a SONET optical transmission rate of 2.48832 Gbit/s used in high-capacity synchronous optical networking.

What is IDE (PIO mode 2)?

IDE (PIO mode 2) is an ATA/IDE interface timing specification for CPU-driven data transfers between host and storage, a legacy mode used by older IDE drives.

Can I use this converter to directly transfer data between OC48 and IDE devices?

No, this converter provides a conceptual performance comparison but does not imply direct interoperability or actual data transfer capability between the two.

Convert OC48 optical transmission rates to IDE (PIO mode 2) timing modes.
Provides standardized framing comparisons between modern fiber networking and legacy device transfer modes.
Ideal for diagnosing and understanding performance in both contemporary networks and vintage storage hardware.
Browser-based and easy to use for quick unit conversions.

Examples

1 OC48 equals approximately 37.4747 IDE (PIO mode 2).
2 OC48 equals approximately 74.9494 IDE (PIO mode 2).

Common Use Cases

Backbone fiber link capacity evaluation for regional network points.
Diagnosing and configuring legacy BIOS or firmware drive timing for older IDE drives.
Understanding ISP uplinks and metro ring transport speeds relative to storage transfer rates.
Troubleshooting performance or compatibility issues on vintage PCs using older IDE devices.
Interpreting device reports that specify PIO transfer modes in ATA/IDE hardware.

Tips & Best Practices

Use this converter to gain conceptual insights rather than exact transfer equivalences.
Apply conversions mainly for network engineering, legacy system maintenance, or hardware diagnostics.
Consider the limitations of the legacy IDE (PIO mode 2) mode when comparing with high-speed fiber optic rates.
Confirm device compatibility separately as this tool does not imply interoperability between units.
Use the conversion to contextualize technology performance across generations.

Limitations

OC48 is a continuous, high-bandwidth network transmission rate, unlike the legacy IDE (PIO mode 2) transfer mode with much lower throughput.
IDE (PIO mode 2) is largely obsolete, constrained by CPU and hardware limits, not suitable for modern high-volume data transfers.
The comparison is conceptual and does not represent direct practical equivalence or interoperability.
Conversion reflects relative performance scale, not a direct mapping of actual data transfer capabilities.
