What Is This Tool?
This converter transforms data transfer values between OC48, a high-capacity optical transmission rate used in networking, and IDE (UDMA-66), a legacy Parallel ATA storage transfer mode. It helps users compare advanced network speeds with older storage device throughput.
How to Use This Tool?
-
Enter the value in OC48 units you want to convert
-
Select IDE (UDMA-66) as the target unit
-
Click convert to see the equivalent data transfer rate
-
Review the result to compare modern network speeds with legacy storage throughputs
Key Features
-
Converts data transfer units from OC48 to IDE (UDMA-66) and vice versa
-
Supports standardized high-speed optical transmission definitions
-
Includes legacy Parallel ATA transfer mode measurements
-
Easy to use for both telecommunications and computer hardware contexts
-
Browser-based tool requiring no installation
Examples
-
1 OC48 equals approximately 4.71 IDE (UDMA-66)
-
3 OC48 equals 14.14 IDE (UDMA-66), calculated as 3 times 4.7127272727
-
Use the formula: 1 OC48 = 4.7127272727 × IDE (UDMA-66) for manual conversions
Common Use Cases
-
Comparing advanced optical network data rates to legacy storage transfer speeds
-
Evaluating backbone fiber link capacities versus hard drive throughput
-
Configuring or diagnosing legacy IDE storage device performance
-
Interpreting benchmarks related to older PATA drives in terms of modern data transfer standards
Tips & Best Practices
-
Always verify the unit context since OC48 is a network rate and IDE (UDMA-66) is a storage burst mode
-
Use this converter for relative comparison rather than precise performance evaluation
-
Consider implementation limits and overhead when interpreting results
-
Apply conversions to understand technology transitions between telecommunications and storage hardware
Limitations
-
OC48 measures network transmission rates while IDE (UDMA-66) reflects storage device throughput, so contexts differ
-
IDE (UDMA-66) speeds are theoretical maximums and actual rates depend on hardware and overhead
-
OC48 is a continuous optical transmission, but IDE operates in burst mode tied to controller and device capabilities
Frequently Asked Questions
-
What is OC48 used for?
-
OC48 defines a high-speed optical transmission rate commonly used in backbone fiber links, ISP uplinks, and metro ring transport networks.
