What Is This Tool?
This converter translates data transfer rates from IDE (UDMA mode 1), a legacy parallel ATA transfer mode, to OC1, the base optical carrier transmission rate used in synchronous optical networking. It helps users relate older PATA device speeds to modern optical telecommunications rates.
How to Use This Tool?
-
Enter the data transfer value in IDE (UDMA mode 1) units.
-
Select IDE (UDMA mode 1) as the original unit and OC1 as the target unit.
-
Click convert to view the equivalent value in OC1.
Key Features
-
Converts IDE (UDMA mode 1) data rates to OC1 rates accurately based on theoretical maximum transfer speeds.
-
Supports legacy and modern networking measurements for comparison.
-
Ideal for troubleshooting and benchmarking vintage computer hardware against current optical networks.
Examples
-
1 IDE (UDMA mode 1) converts to approximately 3.858 OC1
-
5 IDE (UDMA mode 1) converts to approximately 19.29 OC1
Common Use Cases
-
Diagnosing BIOS or drive transfer settings on older PATA hardware by converting IDE UDMA modes to optical carrier equivalents.
-
Benchmarking the maximum throughput of vintage IDE hard drives or optical drives relative to modern OC1 rates.
-
Provisioning and analyzing fiber circuits by comparing legacy data transfer modes with SONET optical transmission levels.
Tips & Best Practices
-
Use this tool to assist with network provisioning involving both legacy storage interfaces and optical trunks.
-
Remember that conversions are theoretical and real transfer performance may vary due to protocol overhead.
-
Ensure proper unit selection (bits vs bytes) when working across different measurement standards.
Limitations
-
Does not reflect real-world data transfer inefficiencies or protocol overhead.
-
Applies only to maximum theoretical rates as defined by standards.
-
Not applicable to modern high-speed data environments due to the outdated nature of IDE (UDMA mode 1).
-
OC1 values are in megabits per second whereas IDE rates involve bytes, requiring careful interpretation.
Frequently Asked Questions
-
What is IDE (UDMA mode 1)?
-
IDE (UDMA mode 1) is an Ultra DMA transfer mode within the Parallel ATA interface for older PATA devices, offering a theoretical maximum transfer rate of about 25 MB/s.

What does OC1 represent?
-
OC1 is the base level for SONET optical transmission with a rate of 51.84 megabits per second, used in synchronous optical networking and telecommunications.
-
Why convert from IDE (UDMA mode 1) to OC1?
-
Conversion helps translate legacy PATA transfer rates into modern optical carrier units for benchmarking, network provisioning, and compatibility analysis.
