What does OC3 represent in data transfer?

OC3 is an optical transmission rate of 155.52 megabits per second used in synchronous optical networking for long-distance and backbone transport.

How is a kilobyte per second (SI) defined?

A kilobyte per second (SI definition) equals 1000 bytes transferred each second.

Why might actual data throughput differ from OC3 conversion results?

Because OC3 includes overhead from framing and protocols, the actual usable data rates may be lower than the raw conversion.

Common Use Cases

Converting backbone optical link speeds to kilobyte per second for traffic analysis
Measuring throughput of leased WAN circuits in enterprise networks
Reporting file download or upload speeds using SI units in applications
Specifying data rates for embedded devices or serial communication links
Describing storage I/O or backup transfer speeds with SI prefixes

Tips & Best Practices

Ensure you select the correct unit definitions to avoid confusion between SI and binary prefixes
Use this conversion for high-level optical network speed analysis and practical data throughput metrics
Remember that OC3 rates may include protocol overhead affecting actual usable data speeds
Confirm that your application context requires SI-based kilobyte units rather than binary kibibytes

Limitations

The tool uses SI kilobytes (1000 bytes), which differ from binary kibibytes (1024 bytes), possibly causing minor discrepancies
OC3 is an optical transmission rate and may include framing and protocol overhead that reduces actual data throughput
This conversion does not account for different network protocols or physical link conditions impacting speed
