What is OC3 in data transfer terms?

OC3 is a SONET optical carrier rate of 155.52 megabits per second used in synchronous optical networking for long-distance fiber transmission.

How is gigabyte per second (SI def.) defined?

A gigabyte per second (SI definition) quantifies data transfer as 1 billion bytes per second, using decimal-based units rather than binary multiples.

Why convert OC3 to gigabyte/second (SI def.)?

Converting OC3 to gigabyte per second helps compare optical transmission rates with standard data throughput measurements used in modern networks and computing.
