What does OC12 represent?

OC12 is a SONET optical carrier rate that carries data at a nominal rate of 622.08 megabits per second and is used in high-capacity fiber-optic telecommunications networks.

How is terabyte/second (SI def.) defined?

A terabyte per second (SI definition) represents the transfer of one terabyte, or 10^12 bytes, each second, equal to 8 × 10^12 bits per second.

Why convert OC12 to terabyte/second?

Converting OC12 to terabyte/second helps translate telecom optical rates into units meaningful for computing, data center bandwidth, and high-performance data processing.

Does this conversion consider network overhead?

No, the conversion is based on nominal OC12 rates and does not factor in overhead, framing, or actual throughput variations.

Is the terabyte/second unit using decimal or binary bytes?

The unit uses the decimal (SI) definition of bytes, which differs from some binary byte conventions.
